Based upon a review on foreign regionalization work, this paper summarized the characteristics of the regionalization work in different stages, gave a brief introduction to the methodology in the regionalization of China, and discussed some issues on the regionalization work. Since the latter half of the 20th century, the regionalization in China has entered a stage of systematic research and all-around development. The main characteristics of the regionalization work in this stage are as follows. First, the various regionalization schemes are based on their historical background respectively. They are the scientific work closely related to the economic development and social demands at the time. Roughly speaking, research on the regionalization in China had mainly served agricultural production since the 1950s. Since the 1980s, the research had been concentrated on economic development. Since the 1990s, the regionalization work has been focused on sustainable development. Second, the work was mostly static and was not able to reflect the dynamics of the changing natural and social factors. And several important boundaries were identified with some assumption and presumption. In recent years, some trends of overemphasizing models and quantification have appeared in regionalization studies. Third, the regionalization studies were inclined to physical geography. The economic geographical regionalization studies were relatively weak. Moreover, current physical and economic regionalization studies are not well related, which has become a limitation to the research of regional sustainable development. Fourth, current regionalization studies focus on terrestrial system, and haven't paid enough attention to marine system. Fifth, the confirmation of regionalization schemes is not institutionally assured yet. So the research results have not been well absorbed by the economic planning of local governments, and the purpose of serving the sustainable socio-economic development has not been realized. Finally, the necessity and importance of carrying out comprehensive regionalization in China was analyzed, and some key scientific issues related with the comprehensive regionalization of China were discussed. The paper pointed out that as a new growing point of regionalization researches, comprehensive regionalization with an integration of natural and social factors will be an important contribution of the human-earthsystem research to the sustainable development.

在回顾国内外区划工作基础上,总结了我国区划工作各个发展阶段的特点,简单概述了我国区划工作中的方法论,讨论了区划工作中存在的若干问题。20世纪后半叶起,我国的区划研究进入系统研究和全面发展期。这期间我国区划工作的主要特点可归纳为:(1)众多区划方案的提出都有其深刻的历史背景,既是科学的总结,又与我国当时经济发展的水平和需求相关;(2)区划工作多是静态的,不能及时反映变化了的自然和人文要素;(3)现有区划工作未能将自然区划和经济区划很好地结合起来;(4)区划工作大多集中在陆地系统,对海洋系统的关注不够;(5)在区划方案的认定上,没有制度化的保障。为此,有必要在我国开展综合区划研究,并就编制我国综合区划方案中存在的一些关键科学问题进行探讨。

The rise of integrated physical geography in China is not an accidental event. It was closely connected with the construction of the related theory system, the fostering of domestic professional scholars, the inheritance of academic history both at home and abroad, and the demand of social development in China. Specifically speaking, it was influenced by the spread of Western modern geography in the early 20th century, and the traditional harmony theory of Chinese ancient geography; it was also associated with the geographical intensive Sino-Soviet academic communications in the 1950s, as well as the needs of economic development in China. All in all, as a branch of physical geography, the integrated physical geography is a practice-oriented subject, focusing on comprehensive perspectives of natural regionalization, land change, and landscape service. The main contents of integrated physical geography studies in China have developed from agricultural regionalization and ecological regionalization to integrated regionalization; from land type, land source to land system; from landscape pattern research to landscape function and service research. Along with the change of the study theme, this subject kept on improving and deepening. Faced with the growing challenges such as rapid urban expansion, serious environmental pollution, and the natural resource exhaustion, the integrated physical geography in China is trying to explore new integrated approaches in accordance with the transformation of the time background. It chooses coupled human and natural systems as its study object, considers the synthesis of processes interaction at different regional scales, makes landscape sustainability as its key research field, and uses big data and high technology as its methodology.

综合自然地理学作为自然地理学的一个独立分支在中国的兴起并非“伊萨钦科讲学”的偶然,而是与之相关的理论体系构建、专业人员培养、中外历史传承及社会实践需求的综合结果。中国综合自然地理学发展一直以实践性为宗旨,围绕着自然区划、土地变化、景观服务等不同的综合视角,经历了从农业区划、生态区划到综合区划研究,从土地类型、土地资源到土地系统研究,从景观格局到景观功能与服务研究等主题的演进,学科体系不断完善和深化。新形势下,综合自然地理学将以人地耦合系统为研究对象,以过程耦合、区域集成为综合方向,以景观可持续性为重点领域,以大数据及高新技术为方法支撑,探索新的综合途径。

As is well known, there exist similarities and differences among geographical regions, and zonality is a universal theorem governing geographical patterns. Physio-geographical regional system is a hierarchical system, which is formed by division or combination of natural features based on geographic relativity and geographic zonality. Researches on physio-geographical regional system aim at observing and studying natural complex of the earth’s surface, revealing rules of regional differentiations and exploring formation, development, division, combination, relativity and demarcation of natural regions at different scales, from a regional point of view. As a radical method to obtain geographical information, physio-geographical regionalization has always been studied and widely used by geographers. Studies on physio-geographical regionalization in China have made great progress in principle, methodology, and theory since the 1930s. It could provide a scientific basis for social and economic development and planning, and conservation, improvement and rational utilization of natural environment. Based on brief review of physio-geographical regionalization at home and abroad, the paper summarizes the characteristics of researches in recent years: various types of elements; distinct ecologicalization in comprehensive natural regionalization; a complete series of spatial scales; scarce creativity in technology and methods; emphasizing regionalization methodology; enhancing application of regionalization schemes. Then, the paper analyzes academic problems in the present researches: lack of epistemological study; weak methodological study. Finally, the paper explores the prospects of physio-geographical regionalization: continuous increase in requirement at the national level; strengthening the standardization of regionalization, and raises several trends in geographical regionalization.

依据自然地带性和区域分异规律进行自然区划历来是自然地理学的重要研究内容。它不仅是获取地理知识的重要途径，而且可为拟定和实施社会经济发展规划以及保护、改良和合理利用生态与环境提供必要的科学依据。本文在简要回顾国内外自然地理区划研究发展历程的基础上，总结了中国近年来自然地理区划研究工作的特点：区划要素类型多样、自然综合区划“生态化”明显、区划空间单元及其尺度系列完整、区划技术方法鲜有创新、区划方法论有所重视、区划方案应用指向进一步强化。分析了当前自然地理区划研究工作中存在的学术问题：认识论研究欠缺、方法论研究薄弱。最后，对自然地理区划的未来发展进行了展望：持续增加的国家需求、不断规范化的区划工作，并提出了地理区划的几个发展趋势。

A new scheme for climate regionalization in China was established based on the daily observations for 609 meteorological stations during the period 1971-2000.During regionalization,current basic theories,classification methodologies and criteria system were used,besides,five principles were taken into consideration,mainly included zonal and azonal integration,genetic unity and regional relative consistent climate integration,comprehensiveness and leading factors integration,bottom-up and top-down integration,spatial continuity and small patch omission.The new scheme consists of 12 temperature zones,24 moisture regions and 56 climatic sub-regions.

根据全国609个气象站1971-2000年的日气象观测资料,遵循地带性与非地带性相结合、发生同一性与区域气候特征相对一致性相结合、综合性和主导因素相结合、自下而上和自上而下相结合、空间分布连续性与取大去小等5个基本原则,在充分吸纳已有气候区划基本理论与区划方法的基础上,参照中国科学院《中国自然地理》编辑委员会制定的气候区划三级指标体系,对我国气候进行重新区划;结果将我国划分为12个温度带、24个干湿区、56个气候区。与先前区划方案相比发现:20世纪70年代以来,中国气候带、区的总体格局并未发生明显变化,但一些重要的气候分界线却出现了一定程度的移动。其中亚热带北界与暖温带北界均出现了北移,北方地区的半湿润与半干旱分界线也出现了不同程度的东移与南扩,同时中温带、暖温带、北亚热带和中亚热带的三级气候区也出现了一定程度的变动;这种变化可能主要是因为20世纪80年代以后我国大多数地区出现不同程度的增暖及北方一些区域出现干旱化而引起的;且与本区划所采用的资料站点和部分区划原则有一定更新有关。

Ecological regionalization is the basis for understanding the spatial heterogeneity of ecological types, structures, processes, functions, and ecosystem services. In this study, we investigated the schemes of ecological regionalization in China. Three types of ecological regionalization were summarized according to systematic reference review:ecological features and types, ecological geography and pattern, and ecological function and ecosystem services. These regionalization schemes have different focuses on evaluating differences and characteristics of an ecosystem, and identifying countermeasures for restoring a degraded ecosystem. We generalized the objectivities, indices, methods, and characteristics for each ecological regionalization scheme. The advantages and shortcomings were also provided by comparing different schemes. Generally, current studies lack regionalization schemes which focus on ecosystem services, particularly for the supply, demand, and flow of ecosystem services. On the other hand, the cartography of ecological regionalization is short of the generating and updating based on remote sensing and big data. Finally, we proposed four potential improvements for ecological regionalization for future studies. First, ecological regionalization should focus on a specific object, such as for scientific theories or management strategies. Second, we need to quantify human demand in the ecosystem service assessment. The tradeoff between supply and demand of ecosystem services should be the basis of ecosystem service mapping. Third, ecological regionalization would be improved by combining the ecosystem services and global change scenarios. The mapping of ecosystem services based on climatic backgrounds and scenarios may be helpful for guiding the adaptation to climate change. Four, modern technologies are important tools in the improvement of ecological regionalization. We need to develop a standard procedure for data collection, processing, storage, and mapping during ecological regionalization. Lastly, current regionalization schemes are useful to ecosystem management even if they are not designated as ecoregions. We need to integrate related regionalization schemes within the framework of ecosystem management and protection.

National-or regional-scale comprehensive geographical regionalization, including the designation of biogeographical regions, can provide foundational data designed to enhance the conservation of biodiversity and the construction of a nature reserve system and so provide a scientific basis for the establishment of policies related to local biodiversity. The comprehensive geographical regionalization supporting natural conservation has become an important aspect of the field of natural geographical regionalization with the development of nature reserves. Meanwhile, China's nature reserve system has been preliminarily established and is developing rapidly. However, no national geographical regionalization system is in place that designates biogeographical regions, considers both biotic factors (such as plant, animal, or vegetation) and abiotic factors (such as climate, soil, or landform), and is also designed to provide a basis for biodiversity conservation and the establishment of nature reserves. This study uses a geographic information system (GIS) to first divide the territory of China into 3489 basic geographical units based regional climate, soil and geomorphology. A regionalization of various aspects of biogeography such as climate, soil, flora, animal distribution, and vegetation was conducted for this study. Then, the spatial information used to create biogeographical regions was compiled and converted into attribute information that could be used to analyze the differences between all the basic geographical units using GIS10.0. Next, the entire set of data supporting these geographical units was studied using TWINSPAN and PC-ORD4.0. Finally, a natural conservation comprehensive geographical regionalization scheme designed to conserve and preserve natural resources was proposed based on the classification results; data from the vegetation regionalization and geomorphologic regionalization were included. Data analysis included quantitative and qualitative analysis during the course of the study. This comprehensive geographical regionalization system resulted in the designation of three major types of natural conservation biogeographical areas, including eight zones, 37 areas, and 117 subareas. A comprehensive geographical regionalization should consider an ideal combination of various elements of the landscape including soil, landform, climate, plants, animals and vegetation to support comprehensive natural area conservation, based on the zonal distribution of various ecological factors and eliminating the interference of intrazonal characteristics. Certainly, the boundaries of a comprehensive geographical regionalization system cannot be determined by the boundary of a single aspect of biogeography, and the biogeographical regions created here will be very different from other previous classification systems because this research integrates the expression of a wide variety of ecological factors in geographical space to consider the needs of biodiversity conservation and provides baseline information in support of the establishment of nature reserves. The features of the comprehensive geographical regionalization system include: (1) A geographical regionalization method that was based on the numerical taxonomic methods of TWINSPAN and GIS, used innovative technology and methods, and provides a new approach for research related to geographical regionalization; (2) Quantitative criteria that are proposed in combination with the existing special regionalization in this study; these criteria helped researchers avoid artifacts in the data that were based solely on one aspect of the data such as unique characteristics of the animal and plant indices, resulting in poor selection of biogeographically-based polygons; additionally, the quantitative criteria can comprehensively reflect natural ecological characteristics in a particular district and can provide good direction to land managers concerned with biodiversity conservation and nature reserve construction; (3) Quantitative analysis was used to ensure that the geographical regionalization system was constructed objectively, while qualitative analysis was used to avoid obvious errors and to improve the accuracy of the classification.

综合自然地理区划可以为生物多样性保护和自然保护区体系建设等提供基础资料，为区域生物多样性政策的制定提供科学依据。随着我国自然保护区事业的不断发展，自然保护综合地理区划成为自然地理区划的重要研究内容之一。虽然我国自然保护区体系已经初步建立，但仍然没有一个同时依据生物因素和非生物因素分布规律，确定的自然保护综合地理区划方案，为生物多样性保护和自然保护区建设服务。利用GIS技术和PC-ORD4.0软件中的双向指示种分析（TWINSPAN）方法，将中国版图划分出3489个基本地理单元，并对这些地理单元进行了数量化分类。然后，根据这个分类结果，参考植被区划和地貌区划等，提出了中国自然保护综合地理区划方案。中国自然保护综合地理区划方案包括了8个自然保护地理大区、37个自然保护地理地区和117个自然保护地理亚地区。该区划具有以下特点：（1）利用TWINSPAN的数量分类方法进行地理区划的探索是区划方法上的创新，为自然地理区划的研究提供了新的研究途径。（2）选取的数量化指标是在结合已有专项区划资料提出的，有助于避免动植物分布指标的人为选择偏差，可以综合反映区域自然地理特征，对生物多样性就地保护和自然保护区体系建设具有较好的指导作用。（3）量化分析保证了地理区划的客观性，同时定性分析避免了量化分析过程中的误差，使区划结果更准确。

Agriculture consolidates the process of natural reproduction and economic reproduction. Spatial pattern of agricultural region is comprehensively influenced by factors such as natural geography, economic and social development and advances in technology. Along with the changes of these influencing factors over a long period, agricultural pattern and agricultural function present regional differentiation and spatio-temporal evolution. This lays a scientific foundation for comprehensive agricultural regionalization. China is currently experiencing a new period of coordinated development of industrialization, urbanization, informatization and agricultural modernization. This paper firstly investigates spatio-temporal changes and dynamic characteristics of modern agriculture development conditions in China. Then, it puts forward the coupling measure index system of agricultural natural factors and regional function, zoning principles and scientific method of modern agricultural regionalization under the new development background. Using cluster analysis and qualitative analysis, it carries out a comprehensive research and puts forward China's modern agriculture regionalization scheme in the new era, which divides China into 15 agricultural first-grade regions and 53 agricultural sub-regions. After doing a comparative analysis with the new scheme and the previous one, which was published in 1981, the paper makes a systematic interpretation on current producing situation, regional function, spatial pattern changes and agricultural development trend of each agricultural region and the whole country at last. The results of this research provide scientific basis for strategic structural adjustment and development of modern agriculture in each region. At the theoretical level, this paper provides a research reference for the development of modern agriculture and rural geography. At the application level, it promotes integrated geography research to serve the rural revitalization and national development strategic needs in the transition period in China. The regional agriculture is a natural, economic and technological complex system, with the characteristics of complexity, dynamics and high risk. As such, based on the congnition of spatial differentiation of modern agriculture development patterns, it is necessary to deeply analyze the regional differentiation of agricultural endogenous power, agriculture and rural territorial types, to improve observational research of agricultural geographical engineering and technology, and the economic, ecological, climatic integrated effects of regional agriculture transformation, to summarize systematically regional agricultural models and regional transformation patterns, to explore the early warning mechanism of modern agricultural complex system, and to study continuously the theories and strategic decision-making for promoting agricultural modernization and rural revitalization.

Aims Our objectives were to consider a new scheme for vegetation regionalization of Northeast China, especially for vegetation in the Songliao Plain, and to illustrate the distribution pattern of vegetation as determined by altitude. Methods We clustered the sites from Inner Mongolia steppe, east forest and central Songliao Plain with temperature, precipitation, soil types and underground water depth using principle component analysis (PCA). We also analyzed the physiognomy, topography of Northeastern China using GIS, vegetation types and soil types of Songnen Plain. Important findings The dominant vegetation of Songliao Plain is meadow, an unzonal vegetation type. The Stipa communities, an indicator of the zonal vegetation type, mainly distributed on the second mesa in Songnen Plain, are a sandland vegetation type that is distributed discontinuously among meadow vegetation. Therefore, the vegetation of Songliao Plain should be regionalized as an area of temperate broad-leaved deciduous forest, and the east boundary of temperate steppe region should be moved toward to the west of the Da Hinggan Mountains. The vegetation distribution of Northeast China shows a vertical zonation determined by altitude.

Studies on spatial-temporal characteristics and influencing factors of flash floods are key contents to the assessment and management of flash flood. Based on the historic flash flood data in southwest China from 1960 to 2015, the spatial and temporal distribution of flash flood and its influencing factors were analyzed by using the linear regression model, standard deviation ellipse, spatial autocorrelation, and logistic regression model. The results show that: (1) The annual frequency of flash floods in southwest China shows an exponential growth trend, and the annual variation reveals a stable, slow and rapid increase fluctuation during 1960-1980, 1981-1998 and 1999-2015, respectively; the monthly characteristics are obvious and precipitation is mainly concentrated in June, July and August. (2) The obvious spatial difference of flash flood is observed in the study area, and the high-density areas are mainly concentrated in central Yunnan plateau, Sichuan Basin and their surrounding mountainous areas. The flash flood distribution has a significant spatial positive correlation and spatial agglomeration (Moran's I index is 0.127, Z = 5.784, P = 0.007). (3) The gravity center of historical disasters has a distinct trend of moving to the west during the year. The standard deviation ellipse angle gradually weakens, the long axis gradually lengthens, and the short axis gradually shortens. (4) Rainfall factors have the maximum impact on flash floods, followed by human activity factors, and the minimal is surface environmental factors. Among the rainfall factors, the one-hour rainfall has the strongest impact on flash floods, and its dominant ratio reached 3.654. The results can provide techinical support for research on forming mechanism, monitoring and early warning, and implementation of disaster prevention and mitigation measures of flash floods.
