| 摘 要： | 贵州省境内土地石漠化现象严重。结合贵州省岩溶生态环境分析表明 :贵州省土地石漠化形成的地质背景是地壳的持续隆升运动和沿断裂破碎带的深切作用 ,使正、负地形高差对比越来越不平衡 ,碳酸盐岩广布为石漠化的广泛发育奠定了物质基础 ;支离破碎的地形地貌给土壤侵蚀提供了有利条件 ,导致严重的水土流失和石漠化 ,独特的气候条件是石漠化发育的主要外营力 ;不合理的人类活动加速了石漠化的进程。

| Abstract: | The phenomenon of land rocky-desertification is severe in Guizhou Province.According to the karst eco-environment characteristics, the main causes of the land rocky-desertification are as follows: (1) its geological background is the continued bulging movement and the slice action of fracture zone;(2) The wide-ranging development of carbonates lays the materialization foundation;(3) The fragile hypsography provides some favorable conditions to the soil erosion;(4) The weather condition of Guizhou Province is the outer power of rocky-desertification;(5) The irrational activity of human beings is accelerating the process of land rocky-desertification. |
