摘要
摘要:以江苏省为研究区，利用1990—2018共4期土地利用数据，借助ArcGIS技术，综合运用生态系统服务价值当量修正法、热图聚类分析、弹性分析、IDW统计分析等方法，分析了江苏省土地利用与生态系统服务价值的时空动态变化特征，探讨了研究区特定土地利用类型动态变化对其所提供的生态服务产生的细微差异．结果表明：1990年以来，江苏省耕地、林地、滨海湿地、河流湿地面积逐渐减少，湖泊湿地、未利用地、建设用地面积不断增加，其中，耕地面积减少最多（9.23×10⁵ hm²），2018年耕地面积为6.50×10⁶ hm²，建设用地面积增加最多（8.59×10⁵ hm²），2018年建设用地面积为1.93×10⁶ hm²；1990—2018年江苏省总生态系统服务价值不断升高，1990年总生态系统服务价值为1.61×10⁴亿元，2018年为1.68×10⁴亿元；耕地、滨海湿地、湖泊湿地对总生态系统服务价值的贡献率较高，研究期内耕地、林地、滨海湿地与河流湿地的生态系统服务价值减少，湖泊湿地与未利用地生态系统服务价值增加；土地利用/土地覆盖(LU/LC)变化决定了生态系统服务价值弹性变化并影响生态系统服务价值，特别是价值系数比较高的土地利用类型，其弹性变化对LU/LC变化的响应更为明显．

Abstract:Land use data from 1990-2018 in Jiangsu Province were analyzed for temporal-spatial dynamics in land use / land cover changes and ecosystem services．Variations in ecosystem services induced by particular land use were revealed．Specifically, ArcGIS was applied for analysis of ecosystem service value equivalent correction, heat map clustering, EEL elasticity and IDW．From 1990, total areas of cropland, forestland, coastal wetland and river wetland in Jiangsu Province were found to have decreased gradually, but areas of lake wetland, unused land and construction land increased continuously．Cropland showed a maximum reduction of 9.23×10⁵ hm², construction land area showed a maximum increase of 8.59×10⁵ hm²．Areas of cropland and construction land in 2018 were 6.50×10⁶ hm² and 1.93×10⁶ hm², respectively．Total ecosystem service value in Jiangsu Province was found to have continuously increased from 1.61×10¹² yuan in 1990 to 1.68×10¹² yuan in 2018．Cropland, coastal wetland and lake wetland have been found to be critical to total ecosystem service value．The ecosystem service value of cropland, forest land, coastal wetland and river wetland were found to have decreased in the study period, but that of lake wetland and unused land have increased．Land use/land cover determined the elastic changes in ecosystem service values and affected total ecosystem service values．Land use type with high value coefficient was found to be more responsive to changes in land use/land cover．
