摘    要:快速城市化背景下,定量评估土地利用/覆被变化对生态系统服务的影响对区域生态环境建设具有重大意义.本文以典型华北平原农区商丘市1990—2015年3期土地利用分类图为基础,对商丘市土地利用和生态系统服务进行时空动态变化分析,并通过构建影响程度评估模型将各类型土地利用变化对生态系统服务的影响进行定量研究.结果表明: 1990—2015年,耕地和建设用地面积占研究区总面积的95%以上,变化量最大,分别为-104.38和201.59 km2;林地、草地和水域面积变化幅度最大,分别是79.3%、-73.7%和-24.2%;生态系统服务总价值持续下降10.05亿元,其中,水文调节服务价值下降最多,生态系统服务价值(ESV)在空间上呈现出“西增东减”的趋势和以市区为中心东西向延伸的“高-低-高”分布格局;耕地和水域对生态系统服务总价值贡献率达95%以上,对生态系统服务的影响最大;商丘市土地利用和ESV变化的主要驱动力是人口压力、经济增长、区域政策和城市规划.在未来的城乡发展规划中,需更加重视自然资源保护,合理调整土地利用结构,实现经济社会与生态环境的可持续发展.

Abstract:Under the rapid urbanization, quantitatively assessing the impacts of land use and cover change (LUCC) on ecosystem service is of great significance for regional ecological environment construction. Based on the land use maps of Shangqiu City (as the typical agricultural area of North China Plain) in the year of 1990, 2005 and 2015, the spatio-temporal dynamics of land use and ecosystem service were analyzed, and the impacts of LUCC on ecosystem services was quantified with the impact assessment model. The results showed that, from 1990 to 2015, farmland and construction land area, which covered more than 95% of the total area of the research area, changed the most in quantity as -104.38 and 201.59 km2 respectively, while forestland, grassland and water area changed the most by 79.3%, -73.7% and -24.2%, respectively. The total value of ecosystem service continuously decreased by 1.005 billion yuan, among which the value of hydrolo-gical regulation service suffered the most. The value of ecosystem service (ESV) presented an increasing trend in the west and a decreasing trend in the east. Extending from the center of the city to the outside, the value of ecosystem services was “high-low-high” in the east to west direction. The rate of farmland and water area contributed more than 95% to the total ecosystem service value, which had the greatest impact. The main drivers for the changes of land use and ESV in Shangqiu were population pressure, economic growth, regional policy, and urban planning. In the urban and rural development planning of Shangqiu City, more attention should be paid to the protection of na-tural resources and rational adjustment of the land use structure to realize sustainable development based on the harmony of economy, society and environment.
