植被对水源地在防风保土、涵养水源等生态效能方面起着关键作用。但西山水源地由于地处南山风口,风灾频发,多年的过度放牧和不合理利用,使得区域内水土流失严重、荒漠草场植被盖度降低、生态与环境退化严重。为解决以上问题,需在生态防护功能优先,生态环保安全的前提下,提高生物多样性和景观异质性;充分利用种质资源,以乡土植物为主;合理利用水资源,建立免灌溉植被系统;提升生态效益、经济效益和社会效益。
Vegetation plays an important role in the conservation of water and soil. There are some ecological problems in Xishan water source protection area because of is located in Nanshan where have frequen and unreasonable use of land. The main problerns are: serious soil erosion, lower cover of t wind disasters, excessive grazing vegetation, serious degradation of ecology and environment. In order to solve these problems, we need to give priority to ecological protection and safe runetions.We should improve the biological diversity and heterogeneity in landscape; rational use native plants, germplasm resources and water source;established the vegetation-free irrigation system; considering environmental ecological results, soeial and economic benefits. Built the modes of vegetation construction and the measures are; give priority to conservation resume, and put corridor restoration as supplement.
