| 摘 要： | 石漠化是岩溶地区脆弱的岩溶地质基础上形成的一种荒漠化现象,它的产生与岩溶环境条件直接相关。通过对流域内的岩性、地貌、岩溶形态、表层岩溶带、地下管道在岩溶水系统中构成的水文网络及动态变化等岩溶环境特征的调查研究,论述了不同环境条件下,对生态环境影响程度及其产生的后果。根据石漠化的分布现状与岩溶环境特征之间的关系,分析石漠化的发展趋势。

| Abstract: | Rock desertification is a certain desertification phenomenon developing in the Karst areas with vulnerable environments,the involvement of which has direct correlation with Karst environment conditions.The influence degree and the subsequent posteffect of rock desertification to entironments were discussed by means of investigation on such characteristics of Karst environments as lithology,physiognomy,Karst configuration,epikarst development and regime change of hydrologic networks formed by subterranean conduits.Moreover,the development trend of rock desertification was analyzed according to the connection between its present distribution situation and characteristics of Karst environments. |
