| 摘 要： | 本文以贵州乌江流域的42个县(市)为例,论述了喀斯特地区生态环境脆弱性区划的主要原则,探讨了脆弱性区划的指标,并进行了量化。在此基础上,用灰色关联度分析并确定了各影响因子(即区划因子)的权重,经过综合评判,笔者把流域内生态环境脆弱性划分为五种类型。并提出了相应的防治对策。

| Abstract: | karst mountain areas are widely distributed in Guizhou province where the eco-enwironment is fragile. This paper, taking 42 counties (or cities) in the Wujiang Basin as examples, deals with the main principles of rcgionalization of the eco-environmental fragility in karst area, discusses and quantifies the index of the fragility regionalization. On the basis of these, the factors affecting fragility-regionalization of the eco-environmetal system are weighted through the analysis of grey correlativity. Finally, five types of the eco-environmental fragility of the Wujiang Basin are divided through comprehensive judgement; extreme fragility region, intense fragility region, intermediate fragility region and potential fragility region, corresponding countermeasures are also suggested. |
