Study on Water Resource Conservation Function of Vegetation and Its Selection in Huangqian Reservoir Area

Through investigating the current vegetation types in Huangqian reservoir area and analyzing the role of main forest types to conserving water resource and soil, the paper makes comprehensive assessment on these vegetation types from aspects of ecological effect and economic effect. The results show that during the vegetation building in Huangqian reservoir area, considering ecological effect and economic effect together in remote mountain and high slope and upper mountain area there should mainly be water resource conservation forest such as locust forest; in the midst area of slope and remote mountain with better stands there should be mainly nut forest such as diospyros kaki forest and Chinese chestnut forest and jujube forest; in the midst and lower part of nearby mountains with better soil condition, there is great potentiality to develop economic forest such as cherry forest and forest apricot forest.
