DOI: 10.19388/j.zgdzdc.2021.02.01
Water is the most active and crucial factor in nature, and it is the main bridge and link among each of the Earth’s circles and natural elements. Besides, water is also the bridge and link connecting various resources in the resource system. The author in this paper has proposed to enhance the observational study of water effect in the natural resource elements observational study, from the perspective of the development of ecological hydrology. The essence of ecological, resources and environmental observation and monitoring research has also been pointed out, from the scientific connotations of three terms, namely ecological balance, ecological environment and resource environment.

LIAO Xiaohan, SHI Chunxiang, WANG Bing
DOI: 10.19388/j.zgdzdc.2021.02.02
The construction of a comprehensive observation system for natural resource elements is an important measure for the Ministry of Natural Resources to fully implement Xi Jinping’s ecological civilization thought, fulfill the development concept of a life community of mountains, waters, forests, farmland, lakes and grassland, and conduct the “two unification” management of natural resources. This basic, public welfare, and urgent construction project is of significant importance in solving the problems of the shortage of long-term and continuous positioning observation research of natural resources, predicting the insufficient support of resources and environmental data, realizing the comprehensive division of natural resources as the management units, evaluating the comprehensive carrying capacity of resources, studying the process of coupling and balance among resources, prejudging the ecological evolution trend of resources and environment, and optimizing the spatial structure of natural resources. Natural resources survey, monitoring and observational research are the main means to obtain the current situation of natural resources and predict the future status. The natural resource survey and monitoring system is relatively complete, while the observational research system is relatively unsystematic, and data accumulation is relatively insufficient in China. In order to preferably build a comprehensive observation system for natural resource elements, the authors in this paper have put forward some suggestions from UVA remote sensing observations, data fusion and natural resources value. The UVA remote sensing observations and oblique photogrammetry should be fully utilized for stereoscopic observation of natural resources. The data fusion of natural resource elements should be developed based on the fusion experience of the research on precipitation, land surface, sea surface and 3D cloud meteorological multi-variate data. Besides, the asset value account of natural resources should be based on the evaluation experience of forest resource ecological service value. These suggestions could provide some reference for the comprehensive observation system of natural resource elements.

DOI: 10.19388/j.zgdzdc.2021.02.03
The coupling effect among the earth system elements has a great impact on our basic activities in order to maintain the stable development of human society, including the development and utilization of resources, the supply of food and living space, and disaster prevention and mitigation. Therefore, the construction of the Earth Observation System (EOS) engineering has been a major task in earth science. The EOS engineering includes three interrelated functional modules, namely, interpreting the coupling mechanism of the earth system elements, improving the prediction ability of development and change trend of the earth system, and providing decision makers with clear action-oriented earth intelligence. Recently, China and the United States have put forward the strategic concept of future EOS. The authors in this paper have compared and analyzed the conception and practice process of the EOS between China and the United States, summarized their similarities and differences, and in the end put forward some implications to China about the EOS work based on the experience of the United States.

YUAN Chengcheng, GAO Yang, LIU Xiaohuang
DOI: 10.19388/j.zgdzdc.2021.02.04
Unifying the connotation of all categories of natural resources and building a unified classification system for natural resources are the prerequisites for achieving the unified management of natural resources. The authors in this research have adopted the literature review method to analyze the basic connotations of natural resources, list all the categories of identified natural resources, and systematically sort out the insufficiency of current natural resources classification systems. Besides, the authors have put forward the consummate suggestions for promoting the unified classification system for natural resources. The results show that the existing natural resources classification systems mainly have three problems, that is focusing on academic classification, defective classification systems, and the absence of comprehensive and systematic enumeration. Based on the challenges above, three suggestions have been put forward. Firstly, the holistic natural resources system should be built, which includes land, geological minerals, forest, grassland, marsh, water and sea. Secondly, the theoretical research on natural resources classification system should be enhanced. Thirdly, the natural resources classification system should be built facing the three dimensional investigation. This research could provide some references for the establishment of China’s natural resources classification system, which will serve the unified management of natural resources.

DOI: 10.19388/j.zgdzdc.2021.02.06
In order to study the coupling and coordination process and laws between natural resources and social economy in the Lower Heihe River Basin in recent 40 years, the authors have taken Ejina Banner as the research object. According to the natural resources and social economy data in the Ejina Banner Statistical Yearbook (1990-2015), the authors have established an indicator system to study the comprehensive development level. The coupling and coordination degree between natural resources and social economy have been analyzed based on the coupling coordination degree model, and the coupling and coordination degree from 2020 to 2030 has been predicted. The results show that the comprehensive development level of natural resources in Ejina Banner has increased from 0.160 0 in 1990 to 0.811 5 in 2015 with an obvious increasing trend. The comprehensive development level of social economy has increased from 0.115 0 in 1990 to 0.713 8 in 2015, also with a continuous increasing trend. Overall, the comprehensive development level curves of the natural resources and social economy are similar. The degree of coupling and coordination between natural resources and social economy has shown an upward trend, which transferred from severely unbalanced economic gain and loss type in 1990 to highly coordinated development synchronization type in 2015, through the antagonistic, development and running-in phases. The coupling and coordination degree between natural resources and social economy would improve in the next 10 years, based on the prediction by the gray theory GM(1,1) model.

DOI: 10.19388/j.zgdzdc.2021.02.10
In order to intuitively reflect the impact of the Nature Forest Conservation Project (NFCP) on the conservation of water and soil function in forest ecosystems and present the ecological benefit, according to the assessment standards of the People’s Republic of China(GB/T 38582-2020 Specifications for assessment of forest ecosystem service in China), the researchers in this paper have taken the key state-owned forest districts in Inner Mongolia Area of China as examples to quantitatively analyze the conservation of water and soil function in forest ecosystems of two stages, including Before NFCP (1988) and After NFCP (2018). The results show that the forest ecosystem in key state-owned forest districts in Inner Mongolia Area of China has an annual value of 950.16×108 yuan in 1998 and 1 341.32×108 yuan in 2018 for water conversation, 563.49×108 yuan in 1998 and 760.11×108 yuan in 2018 for soil conversation. The top three forest bureaus with highest values of forest water conversation before and after NFCP are Genhe, Moerdaoga and Wuerqihan, while the top three forest bureaus with highest values of soil conversation are Genhe, Wuerqihan and Jinhe. The spatial pattern distribution of these two conversation values generally decreased from middle and northern parts to southern part.

TANG Yulei, WU Yangyang, JIANG Xingzheng, FENG Liang, GAO Yang
DOI: 10.19388/j.zgdzdc.2021.02.11
Natural resource indicator data with high spatio-temporal resolution are essential for large-scale natural resource dynamic observation and trend assessment. The large amount of multi-source data under big data era could provide the possibility for efficient utilization and fusion of data. Taking the Normalized Difference Vegetation Index (NDVI) in Hanjiang Basin as an example, the authors in this paper have built a spatio-temporal big data processing underlying architecture for natural resources based on PostgreSQL, and integrated three types of methods, including data-level fusion, feature-level fusion and decision-level fusion. Besides, the intelligent fusion system of multi-source heterogeneous data has been constructed based on the machine learning algorithms to achieve efficient utilization of multi-source data and feature spatial preference. Meanwhile, the year-by-year NDVI 1 km dataset of Hanjiang Basin from 2000 to 2019 has been reconstructed to comprehensively reflect the dynamic changes of vegetation in Hanjiang Basin. These results could provide some scientific reference for the efficient extraction and simulation analysis of spatio-temporal big data in earth sciences, and provide a more accurate and convenient technical means for quantitatively accounting the scale of forest and grassland resources endowment and exploring the spatio-temporal evolution of ecosystem.

LAI Ming, WU Shuyu, ZHANG Haiyan, LIU Jiufen, WANG Xinhua, CHEN Xizhuo
DOI: 10.19388/j.zgdzdc.2021.02.12
In order to study the characteristics of natural resources dynamic changes in Southwest China, the authors in this paper have taken the forest and cultivated land natural resources region of Southwest China as the research object and identified the factor indicators and their weights, based on the results of the first-level regionalization of China’s comprehensive regionalization of natural resources. The second-level and third-level natural resources comprehensive regionalization of this region have been carried out according to the regionalization scheme, and 6 natural resources sub-regions (second-level) and 11 natural resource districts (third-level) have been divided, with the analysis of the characteristics of natural resources dynamic changes within the regions. The natural resources in the study area are mainly forest, cultivated land and grassland, and the natural resources changes mainly focused on the transformation among forest, cultivated land and grassland. The transformation between forest and cultivated land was mainly distributed in Guizhou and Chongqing, while the transformation between forest and grassland and between cultivated land and grassland was mainly distributed in Yunnan and Shaanxi. The area of construction land has increased significantly, mainly distributed in provincial capitals and municipalities directly under the Central Government. All kinds of resources have changed obviously, but the whole area has basically kept a dynamic balance, which means the natural resources have changed within a reasonable range. The cultivated land in Sichuan Basin and the forest in Western Guangxi have been well protected. The superior resources in each division are obvious, and the change characteristics between divisions are different, which can provide some decision support for the unified management of natural resources such as natural resource allocation and land spatial planning.

The study on the dynamic change of comprehensive regionalization of natural resources in North China can help researchers grasp the distribution law and evolution trend of natural resources in detail and provide technical support for the unified management and decision-making of natural resources. Based on the previous regionalization of grassland and cultivated land region in North China, the authors in this paper have selected the land surface natural resource classifications of forest, grassland, wetland, water resources and the closely related factors such as topography and climate, and adopted the grid assignment method to divide the 1990-2018 comprehensive regionalization into 11 secondary natural resource sub-regions and 18 tertiary natural resource regions. Besides, the distribution and dynamic changes of the grassland and cultivated land region natural resources in North China were analyzed on this basis. The results show that the main change of natural resources in the southern sub-region is the conversion of cultivated land to construction land from 1990 to 2018, while the main change of the some northern sub-regions is the conversion of grassland to forest, cultivated land, and desert. The further regionalization of natural resource region in North China is of great significance to the fine management of natural resources and the grasp of the dynamic characteristics of natural resources in typical regions in North China.

DOI: 10.19388/j.zgdzdc.2021.02.14
Based on the study of natural environment, geography and natural resources, the comprehensive regionalization of natural resources is conducive to fully understanding and analyzing the internal natural resources environment status and its dynamic change, which could also provide some decision-making basis for the investigation and supervision of natural resources, the sustainable development and planning of regional economy. In this paper, the authors have adopted the environmental geographical elements and natural resources as the basis to divide different regions and carry out the comprehensive regionalization. The scientific understanding of regional differences and the dynamic change of natural resources could be strengthened through the comprehensive regionalization, which has important guiding significance for the rational development and utilization of natural resources. Through difining the dominant division and auxiliary decision-making elements of the regionalization units, the authors have used the principal component analysis and cluster analysis method to preliminarily divide the comprehensive regionalization of natural resources into three level system. The secondary regionalization includes seven natural resources subregions, while the tertiary regionalization includes 14 natural resources districts. Besides, the temporal and spatial dynamic characteristics for natural resources from 1990 to 2018 at all levels were also quantitatively analyzed. The results show that the overall change of the dominant resources is the decrease of forest resources and the significant increase of cultivated land resources. The specific changes is the transformation from forest to cultivated land and the transformation from grassland to cultivated land.

109 Theories and practice of the comprehensive regionalization of natural resources at a long time scale: A case study of Qinghai-Tibet Plateau
HUANG Li, LIU Xiaohuang, LIU Jiufen, LIU Xiaojie, ZHANG Haiyan
DOI: 10.19388/j.zgdzdc.2021.02.15
Comprehensive regionalization of natural resources is the basis of unified management and utilization of natural resources, and its dynamic change is an important scientific basis for the sustainable utilization of natural resources. Due to the high altitude and cold climate of Qinghai-Tibet Plateau, the largest glacier remains are distributed here except the Polar Regions. The extreme environment and climate have a great impact on the distribution of natural resources. With remote sensing and geographic information system technology, the authors in this paper have selected 14 indicators including glacier snow cover, and used the K-means clustering algorithm to cluster the comprehensive index of natural resources to determine the regionalization range. By using the combination of "top-down" deduction method and "bottom-up" induction method, the division grade was determined. Besides, the comprehensive division of natural resources in the study area was established to discuss the dynamic division changes of the comprehensive division of Qinghai-Tibet Plateau from 1990 to 2018 and analyze the dynamic change characteristics and spatial differences of natural resources. The research results could help researchers to clearly understand the relationship and evolution trend of natural resources in Qinghai-Tibet Plateau, and provide a case for the interdisciplinary application of regionalization.
