黄前库区流域植被水源涵养功能及植被类型选择的研究

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

通过对黄前库区流域现有植被类型的调查和主要类型的涵养水源保持水土作用分析,从生态效益和经济效益两方面对各种植被类型进行了综合评价。结果表明,在黄前库区植被的建设中,从生态和经济效益两方面全面考虑,远山、陡坡和山上部可以刺槐林等水源涵养林为主;山坡中部和管理不便的立地条件较好的远山可以柿树、板栗、枣树等干果林为主;近山中下部土壤条件较好,樱桃和杏树等经济林具有较大的发展潜力。

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.
