西南岩溶石漠化区水资源承载力研究——以贵州省清镇市为例

在分析岩溶石漠化区生态环境特点的基础上,构建了岩溶石漠化区水资源承载力评价指标体系和概念模型,强调岩溶石漠化区水土流失及石漠化综合防治等生态环境需水。以贵州省清镇市为例,以相关统计数据为基础,对清镇市现状和未来10年水资源承载力进行了评价预测,并分析了其水资源供需的现状和未来趋势。预测结果表明:清镇市水资源处于不可持续发展状态,供需矛盾越来越突出。

Carrying Capacity of Water Resources of Karst Desertification Region in Southwest

It builds evaluation index systems and conceptual models of carrying capacity of water resources and emphasizes the eco-environmental water demand in relation to soil and water loss and desertification,based on the analysis of characteristics of ecological environment in karst desertification region.With the related statistic datas,it evaluates and predicts the carrying capacity of water resources of present and the coming 10 years in Qingzhen where is taken as an example,and analyzes the present status and future trends of supply and demand of water resources.The outcomes show that the water resources of the city are unsustainable and the contradiction of supply and demand will become more and more outstanding.
