| 摘 要： | 运用GIS和RS技术,分析了2000年、2010年广东省11个国家级自然保护区的土地利用变化特征,并采用修正的生态系统服务价值系数结合土地利用面积,对不同时期保护区的生态系统服务价值进行了计算. 结果表明:2000─2010年,广东省自然保护区草地、农田、湿地、水域和建设用地面积均有所增加,分别为18.58、81.24、1.91、86.47、70.79 hm2,而林地、未利用地面积则分别减少了166.25、92.75 hm2. 不同土地利用类型的生态系统服务价值量均发生变化,除未利用地外,其余生态系统服务价值均有所增加. 其中,水域和林地2类生态系统服务价值分别增加了728.07×107和463.90×107元,增加最显著. 自然保护区内各项生态系统服务价值均有所增加,其中,维护生物多样性价值、水文调节价值和废物处理价值增加最为显著,食物生产价值增加最少. 2000─2010年广东省11个自然保护区生态系统服务价值增加了1 199.70×107元,增长率为28.02%,表明自然保护区保护和管理成效较好.

| Abstract: | With GIS and RS technologies, the characteristics of land use change in 11 national nature reserve areas in 2000 and 2010 in Guangdong Province were analyzed. Combining the modified coefficients of ecosystem service value and land use area, ecosystem service values of different years were estimated. The results showed that from 2000 to 2010, the areas of grassland, farmland, wetland, water body and construction land increased by 18.58,1.24,1.91,6.47 and 70.79 hm2, respectively, while the areas of forest land and unused land decreased by 166.25 and 92.75 hm2. Except for unused land, all ecosystem service values increased, among which ecosystem service values of water body and forest land increased by 728.07×107 CNY and 463.90×107 CNY, respectively. Multiple ecosystem service values increased, among which values of biodiversity maintenance, hydrological regulation and waste treatment increased most while values of food product increased least. Ecosystem service values in nature reserves increased by 1199.70×107 CNY from 2000 to 2010 (a rate of 28.02%), indicating that the protection and management of the national nature reserves were well conducted in Guangdong. |
