摘要
玛曲县是黄河上游地区的主要水源涵养地,草地生态系统服务价值巨大。近几十年来由于全球气候变化和人为因素的影响,草地退化严重,不仅明显制约了牧区经济的发展和当地藏族群众生活水平的提高,而且直接威胁到黄河流域的生态安全。在分析玛曲草地退化现状及发展趋势的基础上,根据生态恢复学原理,探讨了退化草地生态修复的途径,并提出了巩固治理成果的对策。
Maqu County is the main water conservation region in the upper Yellow River and with great value of grassland ecosystem services. In recent several decades,the grassland is severely degraded because of global climatic change and artificial factors,which not only obviously restricts the economy development of pastoral areas and the improvement of living standard of local Tibetan people,but also directly threatens the ecological security of the Yellow River basin. The paper discusses the way of ecological rehabilitation of degraded grassland and puts forward countermeasures for consolidating treatment effect based on the analysis of present status and development trend of grassland in Maqu Country,according to the principles of ecological rehabilitation.
