喀斯特断陷盆地石漠化演变及治理技术与示范

岩溶断陷盆地区是国家石漠化综合治理工程、生态安全屏障、连片特困区,同时也是石漠化治理科技投入薄弱。针对断陷盆地盆-山共存的环境地质结构分异,及水土资源不匹配和石漠化严重等问题,在滇东蒙自、建水、泸西为重点区,开展"喀斯特断陷盆地石漠化演变及综合治理技术与示范(2016YFC0502500)"项目的国家重点研发活动,阐明流域尺度石漠化演变机理,以水土资源高效利用为基础、生态服务功能提升为核心,研发石漠化综合治理技术,形成生态治理-生态产业协同发展模式,为生态富民和生态文明建设提供技术与示范。形成喀斯特断陷盆地石漠化机理识别-治理技术研发-生态产业模式构建-综合效益评估-国土资源空间高效利用对策等系列成果,培养一支高水平创新团队。

Rocky desertification evolution, treatment technology and demonstration in Karst faulted basins,Southwest China

Karst faulted basin area is ecological security shelter and contiguous poverty zone with paying rare attention to science and technology in comprehensive rocky desertification treatment of national engineering. Many problems like the geologic structure basin-mountain coexistence, water and soil resources in separation and serious rocky desertification still exist there. And these problems have a great influence on regional ecological security shelter function. Based on the National Key Research and Development Program of China "Rocky desertification evolution, integrated control technologies and demonstration in karst faulted basin area, Southwest China", Mengzi, Jianshui, Luxi in the eastern Yunnan are selected as the key study area, the mechanism of rocky desertification evolution at the basin scale would be illustrated, with the enhancement the utilization efficiency of water and soil resources, the ecological service function increasing,will be undertaken. We also build collaborative development model both ecological management and ecological industry, and provide technology and demonstration for ecological enriching people and ecological civilization construction. The expected outcomes of our investigation and research, are the mechanism of rocky desertification in karst faulted basins, technologies on integrated control, models of ecological industry, comprehensive benefit evaluation, and efficient space utilization of land resources, as well as high level of innovation team.
