1990-2015年长三角城市群土地利用转型与生态系统服务功能变化
|
摘要
基于1990—2015年多时序土地利用现状遥感监测数据,分析了长三角城市群土地利用转型过程及其引起的生态系统服务功能变化。结果表明:1990—2015年,耕地、林地和草地面积显著减少,建设用地、水域和未利用地面积显著增加;耕地—建设用地、耕地—林地之间的相互转化是长三角城市群土地利用转型主要模式;生态系统服务价值空间上呈现南高北低分布格局,时间上从1990年的1 717.01亿元减少到2015年的1 682.67亿元;在生态系统二级服务功能中,水文调节功能、美学景观功能持续增强,其他二级服务功能有所减弱;森林、农田、水体生态系统对各单项生态服务价值贡献较大;以耕地—建设用地、林地—耕地为主的土地利用转型模式是引起生态系统服务功能变化的主要动力。
Based on the remote sensing monitoring data of land use from 1990 to 2015,we analyzed the process of land use transition and the changes of ecosystem service function in the urban agglomerations of Yangtze River Delta.The results indicated that during the period from 1990 to 2015,farmland,woodland and grassland significantly reduced,and construction land,water bodies and unused land increased significantly;the mutual transformations of farmland and construction land,farmland and woodland were the main patterns of land use transition in the urban agglomerations of Yangtze River Delta;with respect to the spatial distribution pattern of ecosystem service value,ecosystem service value was higher in the southern area than that in the northern area,and decreased from 171.701 billion yuan in 1990 to 168.267 billion yuan in 2015;in the two-level ecosystem service function,hydrological adjusting function and aesthetic landscape function continued to improve,while other two-level service functions diminished;forest,farmland and water ecosystem made great contribution to single ecosystem service value;the land use transitions of farmland-construction land and farmland-woodland were the main drivers of changes in ecosystem service function.
