青海高寒牧区土壤荒漠化现状及防治对策的研究

THE STUDIES ON THE ACTUALITY OF THE GRASSLAND AND THE PROTECTIVE MEASURES IN THE PASTORAL AREA OF QINGHAI

草地是具有重要生态、经济功能和价值的自然资源。草地的天然牧草通过家畜转化,可为人类提供乳、肉、皮、毛等廉价畜产品,从而使草地畜牧业成为牧区经济和农牧民赖以生存和发展的支柱产业;草地作为陆地最大的生态系统,具有涵养水源、调节气候、防风固沙、美化环境、净化空气等生态功能,对维持生态平衡,维系生物多样性,保护人类生存环境发挥着巨大作用;与此同时,草地的自然景观和区域人文景观还具有重要的开发利用价值。因此,加强草地生态环境的保护和建设,不仅是经济发展的需要,而且对于提高人类的生存质量有着重要的意义。为此,本文对青海草地土壤荒漠化现状、原因、危害进行了初步的探索,提出了防治土壤荒漠化的基本思路及措施对策。
