摘要
在西南地区分布着以贵州为中心的、面积约 5 4万km2 的碳酸盐岩山区 ,它是我国喀斯特地貌最发育的地区。同时也是石漠化最严重的地区。石漠化的产生与发展既有自然方面的原因 ,又有人为方面的原因 ,究其根本原因 ,是其岩溶生态系统中土壤这个关键因子的脆弱性所致。
Karsts mountains are distributed wildly around Guizhou province in the southwest of China, and its square is about 540 000 sq.km. Karst landforms developes completely in this region. It is also the most serious land rocky desertification. The article regards rocky desertification as co_impact by karst natural proceed and human activities, but it is fragility of soil that is essential for land rocky desertification. On the basis of these the thesis expatiate the reasons and control of rocky desertification, some concrete countermeasures are put forward.
