Flood Water Resources Utilization Mechanism Based on Spatial Configuration of Typical Karst Landform:A Case Study of Guizhou Province
摘要
Abstract
Flood Water Resources Utilization (FWRU) is an effective way to solve the serious water shortage problem in Karst areas. This paper selected 40 basins in Guizhou province as the samples to extract the typical Karst landform types by using the supervised classification method of object-oriented technology, and analyzed the characteristics of those sample areas. Then the paper used the method of systematic cluster to classify the sample areas into six basin types, which are:Karst low-medium mountain type (Ⅰ), peak-cluster valley type (Ⅱ), mixed type (Ⅲ), peak forest basin (rongyuan) type (Ⅳ), peak-cluster depression type (Ⅴ), and peak forest landform type (Ⅵ). With the correlation analysis method, the paper analyzed the effects of different landform spatial configurations on the flood runoff characteristics values (i.e. the flood runoff coefficient and flood runoff modulus), explored the allocation and loading rules of landform spatial configurations on floods, and researched the realization of FWRU under different landform spatial configurations from the view point of basin structures. The results show that:1) the curves of Flood Runoff Modulus (FRM), Flood Runoff Coefficient (FRC) and Coefficient of Variation (Cv) presented“double-peak type” distribution, and at the peak-cluster valley basin (Ⅱ) and peak-cluster depression basin (Ⅴ) they reached the maximum values;2) the descending order (unit:billion cubic meters) of the total amounts of flood resources utilization for different basin types is Ⅴ(0.622)>Ⅰ(0.288)>Ⅵ(0.149)>Ⅱ(0.134)>Ⅳ(0.125)>Ⅲ(0.055); 3)the total amounts of underground flood resources for all the basin types, except type II and type III, are greater than that of surface flood resources.关键词
