摘要
喀斯特流域是由可溶性岩石组成的有独特地貌、水系结构及水文过程组成的地域综合体。对河流径流影响因素是错综复杂的,除气候条件外,下垫面也是重要影响因素。通过对贵州省19个喀斯特流域为研究样区,以1991～1995年水文资料和遥感解译数据为基础。运用灰关联度和关联维分析方法,分析土地利用类型、岩石组成类型、植被类型对喀斯特枯水径流的影响识别。
The valley is composed of soluble rock and the landforms is unique, water and hydrological process on the structure of the geographical complex in Karst. The river run-off factors are complex, with the exception of the climate, surface factors of the landforms also affect an important factor. Study plots to 1991-1995 hydrological information and interpretation of remote sensing data as a basis, 19 Karst valley, in the Guizhou province. Using Gray correlation analysis and correlation dimension method research land-use types, composed of rock types, vegetation types of Karst, the impact of low water runoff.
