Other Abstract

 以小流域为基本单元,采用灰色关联及统计分析方法,结合地理空间技术识别岷江上游不同植被类型及覆盖度与山洪灾害的关系特征,结果表明:1在不考虑植被覆盖时,岷江上游山洪灾害潜在危险性较高,并存在空间分异,干流及一级支流的中下游潜在危险性较高,而干流上游及小姓沟、黑水沟部分区域其值较低;2根据灾害发生实际情况,该区域的植被具有减洪能力,缓解程度与潜在危险水平存在相关性;3不同植被类型及覆盖下,植被的减洪能力也存在差异,并与覆盖度存在不同程度相关性。

A favorable eco-environment has a function of reducing flood,while vegetation cover is an important index to measure the eco-environment quality. Researching on small watersheds,using grey correlation analysis and statistical method combined with GIS,this paper analyze how various vegetation types and different vegetation cover reduce flood in upper Minjiang river basin. The results show that: ( 1) Generally the potential risk of flood in upper Minjiang river basin is relatively high,and exists spatial difference,the high value is mainly distributed in middle and lower reaches of main channel of Minjiang river and its first tributaries,the low value is mainly distributed in upper reaches of main channel of Minjiang river and region of Xiaoxinggou,Heishuigou and so on; ( 2) According to the actual happens of disasters,vegetation in the region have flood reduction ability,there is an association between flood reduction ability and potential risk of flood; ( 3) Under different vegetation types and coverage, flood reduction ability is different,and there is a different degree of correlation with coverage.
