摘 要:本文建立了四川省草地生态系统服务价值评价指标体系,初步估算其年度服务价值,并通过确定人为破坏率来评估四川省草地生态系统破坏损失价值。结果表明,目前,四川省由于人为破坏造成草地生态破坏损失达到370.55亿元,占2010年全省地区GDP的2.16%,其中,水土保持贡献率最大,达到34.52%。过度放牧是造成四川省草地生态系统破坏的重要原因。In this paper, the evaluation index system of service value for grassland ecosystem in Sichuan Province was established. Its annual service value was preliminary estimated. By determining the man-made damage rate, the loss value of grassland ecosystem damage in Sichuan Province was estimated. The results showed that the losses from grassland ecosystem damaged by human in our province amounted to 37.055 billion RMB, accounting for 2. 16 percent of the regional GDP of Sichuan Province in 2010. The highest proportion contributed by the respect of soil and water conservation, account for 34.52%. Overgrazing was found to be the important factor to damage the ecosystem of grassland.
