Evaluation of construction suitability of gentle slope based on geological survey: A case study of Jianyang central district of Nanping City in Fujian Province
Abstract：In order to construct the suitability evaluation system of gentle slope, and reasonably delimit development suitable area, general suitable area and forbidden construction area, the authors take the central district of Jianyang City in Fujian Province as the study case for scientific development and utilization of gentle slope resources. Based on comprehensive geological survey, the authors used small watershed as basic evaluation unit, and denudation terrace as a replacement for slope and fluctuation to conduct the evaluation of land resources with urban construction function. Geological hazard risk was assessed according to main indicators, including topographic slope, soil thickness, consistency of slope aspect and stratum occurrence, lithological construction and vegetation type. A multidimensional system of ecological protection importance and construction suitability was constructed to evaluate the construction suitability of gentle slope. The results show that the gentle slope suitable for urban construction in the central urban area of Jianyang is rich, mainly distributed in first-grade degradation terrace with little geological risk, including Yandun, Xinling, Xingtian, Jiangkou, Nanlin, Chi'an, Qinkou and other areas, which can be developed and utilized step by step according to the way of cluster development. Jianyang central district belongs to non-prone geological risk area, but the second-grade and third-grade degradation terrace in Xi'an and Shuiwei watershed have thick soil mass and steep slope with lanceolata and moso bamboo. Once the development boundary is unreasonable, these areas are easy to cause landslide and collapse and should be paid attention to. This research has some guiding effect on the rational development and utilization of low hills and gentle slopes in China.
