| 摘 要： | 岩溶生态环境作为一种脆弱型的生态系统,不仅由自身特殊的水文地质条件所决定,还由于人们不合理的经济活动而导致生态系统多样性趋向简单化,造成水土不断流失,从而陷入“环境生态脆弱—贫困”这样的恶性循环中。因此,研究岩溶生态脆弱性为生态恢复及重建提出相应的改进措施具有重大的现实意义。本文通过分析各生态因子对岩溶生态的作用来研究其脆弱性。

| Abstract: | As a fragile ecosystem,ecological environment in the Karst region is associated not only with its special hydrologic and geohydrologic features but also with anthropogenic activities unreasonable,which causes diversity of ecosystem to tend to simplification,and makes soil continuously erosion and desertification.Accordingly,ecosystem gets into a vicious circle of environment ecological fragility-poverty.Therefore,the aim of the research on fragility of ecosystem in the karst region has important practical significance in renewing and reestablishing ecosystem.In this paper fragibility of ecosystem is studied by analyzing each ecological factors. |
