喀斯特地区枯水资源承载力评价及空间分布研究

Study on the carrying capacity estimate and spatial distributing of low water resources in karst region

利用地理信息系统的空间分析功能和遥感的快速、准确获取有效信息的功能,并结合灰灰关联度分析对贵阳地区的枯水资源承载力进行了分析评价,这种评价方法避免了喀斯特地区枯水资源承载力评价标准还不确定的因素,仅用到了各评价指标的原始量化值,评价结果更为直观、科学,对枯水资源承载力的评价具有较大的参考价值。

The research of low-flow water resources carrying capacity has increasingly given rise to high concern of karst region and the non-karst areas. The use of spatial analysis functions of GlS,rapidly and accurately attain effective information functions of remote sensing, and combining with the analysis of the grey related degrees, analysed and evaluated the low-flow water resources carrying capacity of Guiyang,gray areas in Guiyang. This evaluation methods avoid such a uncertainty indicators which we determine the evaluation criteria of the karst low water resources carrying capacity,and only used the original evaluation indicators, the result is more intuitive, scientific, this has more greater reference value on the evaluation of low water resources carrying capacity.
