摘要
以洪泽湖周边地区(包括淮安市淮阴区、洪泽县、盱眙县,宿迁市宿城区、泗洪县及泗阳县)1996、2005年的土地数据为基础,采用Costanza生态系统服务价值计算公式,参照谢高地的生态系统服务单价,评估了洪泽湖周边地区1996—2005年土地利用变化对区域生态系统服务价值的影响.结果表明研究期内洪泽湖周边地区土地利用变化显著,并造成生态系统服务价值减少691·06×106元,水域和草地减少是生态系统服务价值下降的主要原因.因此,今后应控制减少占用水域、草地的行为,以提高生态系统的服务能力.
Based on the land data of 1996 and 2005 two years, the paper analyzes land use change in surrounding Hongze Lake region. Using the Costanza ecosystem service value (ESV) calculation formula and according to the Xiegaodi ecosystem service unit price, We evaluate the ecosystem services value change affected by land use change in surrounding Hongze Lake region from 1996 to 2005. The research indicated that the total ESV decreased 691.06 × 10^6 yuan. The decrease of the ecosystem service values was mainly responsible to the reduction of water bodies and grasslands. Therefore, in order to improve the service ability of ecosystem, we should be controlled to take water bodies and grasslands.
