岩溶生态脆弱性研究

The Research of Karst Ecological Fragibility

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。

As a fragile ecosystem, ecological environment in Karst region associate not only with its special hydrologic and hydrogeologic features but also with unreasonable destructive human activities,which causes diversity of ecosystem tending to simplification,which makes soil continuously eroding and becoming deserdfication. Accordingly, ecosystem gets into a vicious circle of environment ecological fragibility-poverty. Therefore, the aim of research fragibility of ecosystem in the karst region has important practical significance in renewing and reestablishing ecosystem, In this paper fragibility of ecosystem is studied through analyzing each ecological factors,
