中文摘要：

以北京市海淀区为例,在对区域土地利用现状进行划分的基础上,基于格网尺度估算了区域生态系统服务价值,并根据价值分布状况将区域划分为不同的生态系统服务价值分区,基于GIS和FRAGSTAS软件,分析了不同分区的土地利用结构和景观格局状况。结果表明：海淀区格网的生态系统服务价值处于-234.56-207.97万元之间,并呈现明显的从南部到西北部增加的趋势;不同生态系统服务价值分区土地利用结构差距较大,高值区的土地利用类型主要为城市绿地,中值区土地利用类型面积较大的为耕地和城市绿地,低值区建设用地的面积较大;不同生态系统服务价值分区的景观格局指数变化较大,从高值区到低值区,景观格局的破碎化程度逐渐增加,人类活动对生态环境的影响不断加剧,人类活动对景观的干扰程度加大。研究结果可以为精细化评估区域生态系统服务价值提供参考,并能服务于区域土地利用结构调整和可持续利用及生态景观建设。

英文摘要：

The regional ecosystem service value of Haidian District in Beijing was estimated in the 500 m ×500 m grid scale by using present regional land use data. The research area was divided into different types of sub-regions according to the distribution of ecosystem service values. The land use structure and landscape pattern of different sub-regions were analyzed through the software of GIS and FRAGSTAS. The results showed that the ecosystem service value of Haidian District was ranged from -2.35 million yuan to 2.08 million yuan, which was increased from the south to northwest. The land use structure and ecosystem service value were different in different sub-regions. The main land use types were urban green space in high value regions, cultivated land and forest land in mid value regions and construction land in low value regions. There were also large differences of landscape pattern index among different sub-regions of ecosystem service value. The fragmentation of the landscape pattern was gradually increased from low value regions to high value regions, indicating that the influence of human activities on the ecological environment was increased, and the disturbing of human activities on the landscape structure was also increased. The results of this research can provide a reference for the intensive evaluation of regional ecosystem service, and serve as a scientific basis for the structure adjustment, sustainable utilization of regional land and ecological landscape construction.
