【摘要】：以北京绿地生态系统作为研究对象,利用2000、2006及2012年的遥感影像数据,在GIS的支持下,对2000—2012年北京绿地生态系统服务价值的时空变化规律进行了研究,结果表明:2000、2006以及2012年北京市绿地生态系统的服务价值差异较小,生态服务价值分别为:369.03、371.86和370.85亿元。其中林地与耕地的生态服务价值占绿地生态系统服务总价值的95.27%,林地生态服务价值2000—2006年增加较显著,增幅为6.5%,2006—2012年增幅较小,增幅为0.7%;耕地生态服务价值呈逐年降低趋势,且降幅显著,2000—2006年生态服务价值降幅为21.2%,2006—2012年降幅为7.3%。2000—2006年时间段,绿地生态系统服务价值减少区域主要集中在北京市东南部的平原区域、延庆东部、怀柔中西部以及昌平西北地区,增加区域主要集中在北京北部山区和西南部山区,在延庆、怀柔以及昌平区均有分散性显著增加区域。2006—2012年时间段,北京市大部分区域绿地生态系统服务价值均呈减少趋势,增加区域相对较少且呈零星点状分布。绿地生态系统所提供的各项服务价值的大小顺序为,土壤形成与保护气体调节生物多样性水源涵养气候调节废物处理原材料食物生产娱乐文化。2000—2006年北京绿地生态服务价值增加缓慢,2006年以后呈现出下降趋势。此研究成果可对北京城市管理、规划、建设及环境保护提供科学依据。
[Abstract]:Taking Beijing greenbelt ecosystem as the research object, using the remote sensing image data of 2000.2006 and 2012, with the support of GIS, the temporal and spatial changes of the service value of Beijing green space ecosystem from 2000 to 2012 were studied. The results showed that there was little difference in the service value of the green ecosystem in Beijing between 2006 and 2012, and the value of ecological service was respectively 37.085 billion yuan and 369.03371.86 yuan. The ecological service value of forest land and cultivated land accounted for 95.27% of the total value of green land ecosystem service, and the value of forest land ecosystem service increased significantly from 2000 to 2006, with an increase of 6.5% and a small increase in 2006-2012. The value of ecological services of cultivated land decreased year by year, and the value of ecological services decreased significantly from 2000 to 2006 by 21.22.The decline of the value of ecological services in 2006-2012 was 7.3.2000-2006. The areas where the value of greenbelt ecosystem services are reduced are mainly concentrated in the plain areas in the southeast of Beijing, in the eastern part of Yanqing, in the central and western Huairou regions and in the northwest of Changping. The increasing areas are mainly concentrated in the northern and southwest mountains of Beijing, and in Yanqing, Huairou and Changping increased significantly in the period from 2006 to 2012. The value of green space ecosystem services in most regions of Beijing showed a decreasing trend, and the increasing areas were relatively small and distributed sporadically. The order of the value of the services provided by the greenbelt ecosystem is, Soil formation and gas conservation water conservation climate regulation waste treatment raw material food production recreation culture. The value of ecological services of Beijing green space increased slowly from 2000 to 2006 and showed a downward trend after 2006. The results can provide scientific basis for urban management, planning, construction and environmental protection in Beijing.
