Other Abstract



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.
