摘要
生态系统服务时空变化研究能够为自然资源管理与土地利用规划提供指导。基于忻州市2000,2010年土地利用数据,分析了忻州市土地利用与生态系统服务价值时空变化,探究了土地利用对生态系统服务价值的影响。结果表明,2000—2010年忻州市土地利用变化整体表现为耕地与湿地减少,林地、草地、水体与建设用地增加的趋势;耕地主要转变为草地,林地主要转变为草地与耕地,草地主要转变为林地与耕地。生态系统服务降低的区域(集中于西南部)占忻州市总面积的1.66%,而增加的区域(集中于中部)占2.45%;代县、繁峙、偏关、五台、忻府与原平生态系统服务表现为增加趋势(忻府与原平增加幅度最大),其他县区表现为降低(静乐与岢岚降低幅度最大)趋势。食物生产主要由耕地、建设用地与草地的变化引起,原材料生产主要受林地控制,气候调节与土壤保持等调节、支持与文化服务主要受林地、草地、湿地与水体变化控制。未来应加强自然资源保护,继续实施退耕还林(草)等恢复政策。
T he study of ecosystem services(ESs) temporal and spatial variation can provide guidance for natural resources management and land-use planning. The land-use map of Xinzhou city in 2000 and 2010 was selected, and the land-use and ecosystem services temporal and spatial variation were analyzed. The results showed that during this 10 years, the cropland and wetland decreased,and forest land, grassland, water body and construction land increased. The cropland was mainly transferred to grassland, forest land was mainly transferred to grassland and cropland, grassland was mainly transferred to forest land and cropland. The region that ESs was reduced, which was mainly distributed in southwest, accounting for 1.66% of Xinzhou area, whereas the region that ESs increased was mainly distributed in the midland, accounting for 2.45% of Xinzhou area. The ESs in Daixian, Fansi, Pianguan, Wutai, Xinfu and Yuanping showed increasing trends(the increased range of Xinfu and Yuanping was the highest), and the ESs in other counties showed decreasing trends(the decreased range of Jingle and Kelan was the highest). Food production was mainly influenced by the change of cropland, construction land, and grassland. Raw material production was mainly influenced by the change of forest land. The other ESs were controlled by forest land, grassland, wetland, and water body. In the future, the conservation of natural resources must be strengthened, and the Grain-for-Green Program must be implemented furtherly.
