No. 6843 The projects of Yunnan University and other units passed the evaluation of scientific and technological achievements

　　On October 29, 2021, the third-party professional scientific and technological achievement evaluation agency, the Zhongke Hechuang (Beijing) Scientific and Technological Achievements Evaluation Center, organized experts to jointly complete the "Soil Erosion Mechanism and Land Degradation Early Warning of the Southwest Plateau Mountainous Area" jointly completed by Yunnan University, Yunnan Provincial Water Conservancy and Hydropower Research Institute and Yunnan Provincial Soil and Soil Conservation Ecological Environment Monitoring Station in Kunming in accordance with the relevant provisions of the "Science and Technology Evaluation Measures" of the Ministry of Science and Technology, in accordance with the standards and procedures for the evaluation of scientific and technological achievements, and in line with the principles of science, independence, objectivity and justice. The project conducted an evaluation of scientific and technological achievements.

　　The expert committee on the evaluation of the results was composed of Cai Qiangguo, researcher of the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences, Liu Guobin, researcher of the Institute of Soil and Water Conservation of the Chinese Academy of Sciences and the Ministry of Water Resources, Liu Baoyuan, professor of Beijing Normal University, Chen Liding, researcher of the Research Center for Eco-Environment of the Chinese Academy of Sciences, Ning Duihu, senior engineer of the International Sediment Research and Training Center, Shi Zhihua, professor of Huazhong Agricultural University, Zhang Zhiqiang, professor of Beijing Forestry University, and Chen Hongsong, researcher of the Institute of Subtropical Agroecology of the Chinese Academy of Sciences. Nanjing University Professor Zhang Yongguang and other experts are composed.

　　After expert review, it is believed that the project is aimed at the bottleneck of regional soil erosion intensity in view of the special geographical environment of the mountains of the Southwest Plateau, and the key impact factors of soil erosion, the investigation method of regional soil erosion, the impact of erosion on soil productivity and the early warning of land degradation are systematically studied, and the main results are as follows: the spatial and temporal differentiation characteristics of rainfall erosion, soil erosion, terrain and soil and water conservation measures factors in the mountains of the Southwest Plateau are elucidated. It was found that soil erosion in plateau mountains is actively sensitive to soil and water conservation measures and catchment water surfaces, and the process and mechanism of soil erosion in the complex environment of plateau mountains are revealed; the automatic extraction technology of soil and water conservation engineering measures factors is developed, the high-precision soil erosion topographic factor extraction technology is developed for the mountainous terrain characteristics of the southwest plateau, the calculation method of rainfall erosion force of plateau mountains is revised, and a high-precision and full-coverage plateau mountain soil erosion survey technology system is formed, which is widely used in soil erosion survey in Yunnan Province The influence mechanism of mountain erosion on soil productivity in the Southwest Plateau is revealed, and the parameters of the internationally common soil productivity index model (PI) are revised, which significantly improves the application accuracy of the model in this area, and provides an effective means for evaluating the impact of erosion on soil productivity, quantitatively calculating the allowable soil erosion and early warning of land degradation The first atlas of soil and water conservation engineering measures with an accuracy of 1:5000 at the provincial scale and the first topographic factor database with spatial resolution of 5-10m at the provincial scale in China have been established. The project has published 2 monographs, 1 atlas, 51 academic papers, 5 authorized invention/utility model patents, and 1 software copyright, and the project results have been widely used in the Ministry of Water Resources and Yunnan Province in soil and water conservation and ecological construction, with remarkable benefits. The project has reached the leading level in China, and has reached the international advanced level in the relationship between soil erosion mechanism and erosion and soil productivity in plateau mountainous areas. After comprehensive review by the expert group, the participating experts unanimously agreed that the project of "Soil Erosion Mechanism and Land Degradation Early Warning in the Mountainous Area of the Southwest Plateau" passed the evaluation of scientific and technological achievements.
