摘要
根据云南省岩溶地区石漠化土地空间分布特征和各区域地质地貌、气候、水文、岩溶土壤和森林植被分布,结合碳酸盐岩的类型、岩性组合特征、不同岩溶地貌对区域环境和水土资源的制约、石漠化在不同地貌条件下的形成和发育特征,统筹考虑岩溶生态系统的完整性、地理单元的连续性和经济社会发展的可持续性等因素,将全省88 个岩溶监测县划分为 6 个治理区,并就各分区地理区位、地质地貌、成土母岩、水文、气候类型、森林植被类型分布以及各石漠化区不同类型岩溶土地面积占比等进行描述.
Abstract
Based on the spatial characteristics of rocky desertification land in Yunnan karst areas and the distribution of geological landforms,climate,hydrology,karst soil and forest vegetation in various regions,the types and lithological combinations of carbonate rocks,the constraints of different karst landforms on regional environment and water and soil resources,the formation and development characteristics of rocky desertification under different geomorphic conditions were studied.88 karst monitoring counties in the prov-ince were divided into 6 governance areas considering factors such as the integrity of karst ecosystems,con-tinuity of geographical units,and sustainability of economic and social development.The geographical loca-tions,geological landforms,parent rocks,hydrology,climate types,distribution of forest vegetation types,and the proportion of different types of karst land in each rocky desertification area were described.
