摘　　要：受喀斯特特殊地质环境的影响,滇东南岩溶区的生态环境相对脆弱,这些地区土壤先天总量不足,土被分布不连续,水土流失后常常会出现土地石漠化。本文通过对滇东南岩溶山地地区不同条件(包括地形、海拔高度和植被情况)下土壤厚度和植被覆盖度等植物生长状况的调查,分析了该地区植被类型、覆盖度与土壤厚度的关系。Affected by the special geological environment, the ecological environment of the karst region in southeast Yunnan is relatively fragile. Due to innate soil insufficiency and discontinuous distribution of regolith, stony desertification often appears after water and soil erosion. Through investigation of the soil thickness and vegetation coverage and other plant growing condition under different conditions （terrain, elevation and vegetation） in the karst mountainous regions in southeast Y-unnan, this article analyzes the relationship between vegetation type, coverage and soil thickness.
