摘要
在分析了脆弱生态环境的性质、退化过程以后 ,从西南岩溶山地脆弱性的成因出发 ,探讨性地将其划分为基底性脆弱、界面性脆弱、波动性脆弱 ;三种脆弱性综合起作用 ,但在不同时空尺度、不同岩溶地貌类型区有主次之分。在此基础上 ,提出了需进一步研究的问题。
Based on the analysis on the characteristics and degrading processes of the vulnerable eco-environment, this paper suggests that the fragility of eco-environment in karst mountain should be divided into matrix fragility resulting from karstification, interface fragility resulting from complicated transition of ecotone landscape, and fluctuation fragility resulting from the spatial-temporal differences of climate; and these different fragile characteristics have a comprehensive effect and affect each other, but one of them may be the major in different scale and different karst geomorphic types. At last, this paper expounds the problems for further studies.
