摘要： 运用GIS和RS技术,基于2000—2010年遥感数据分析了新疆6个国家级自然保护区的土地利用变化状况,并对不同时期的生态系统服务价值进行评估.结果表明: 2000—2010年,研究区水域和草地面积有所减少,林地、农田、湿地、未利用地和建设用地面积均有所增加,2000—2005年间土地利用变化速率较快,约为2005—2010年间变化速率的2.4～6.3倍.水域、草地、林地生态系统价值构成了研究区生态系统总价值量的主体,约占93%.研究期间, 除草地和水域生态系统服务价值有所降低外, 其余地类的生态系统服务价值均有所增长;生态系统服务总价值先升高后降低,整体呈降低趋势,降低率为1.2%.在西部大开发过程中,需要更加重视自然资源的保护和生态系统修复,以实现西部地区资源、环境与社会经济的可持续发展.

Abstract: With GIS and RS technology, characteristics of land use change and ecosystem services value of different years in six national nature reserves in Xinjiang, China were analyzed with remote sensing image of the year 2000-2010. Results showed that the area of water body and grassland decreased while the area of forest, farmland, wetland, unused land and construction land increased in 2000-2010. Variation rate of land use change in 2000-2005 was faster, as 2.4-6.3 times as that in 2005-2010. The total ecosystem services value mostly consisted of that of water body, grassland and forest, accounting for 93% approximately. During the study, the values of all kinds of the ecosystem services increased except for grassland and water body, the total ecosystem services value increased firstly and then decreased, and overall emerged as a reducing trend with the rate of 1.2%. In the process of the development of the west regions, it is necessary to pay more attention to the protection of natural resources and ecosystem restoration, so as to achieve sustainable development of resources, environment and social economy in the western regions.
