摘　　要：岩溶地区土壤和植被是生态环境中最为敏感的自然环境要素,不同土壤类型塑造了不同的土地利用类型和植被景观。文章分析了重庆岩溶形成的地质背景,土壤类型分布特征及其不同土地利用下石漠化程度,论述了植被演替规律;并在此基础上提出了适生植物树种及其重庆岩溶地区土壤-植被生态系统恢复与建设的可行性措施。The soil and vegetation of karst region are the most sensitive element of natural environment in ecological system. Different soil types shaped different soil utilization type and vegetation view. This paper analyzed the geological background which leads to the formation of Chongqing karst region, the distribution characteristics of soil type and the degree of stone desertification under different land utilization and elaborated the vegetation succession rules. Based on above, it put forward some plants and trees species which are suitable for the land and workable measures for restoration and construction of ecological system of Chongqing karst region.
