| 摘 要： | 淮安市地处黄淮平原和江淮平原，境内河湖交错，水系纵横，是江苏省北部的农业大市。研究其耕地时空变化特征及其驱动因素可为保障粮食生产和农业可持续发展提供指导。基于2000、2010和2018年3期土地利用数据，综合土地利用转移矩阵、土地利用动态度和多元逐步回归分析等对2000—2018年淮安市耕地的时空变化特征进行分析，并结合社会经济指标研究其驱动力。2000—2018年耕地减少速度不断加快，减少面积主要集中在清江浦区北部，与城乡工矿居民用地相互转移面积较多。耕地变化受经济发展和收入水平的影响，第三产业是耕地变化的核心驱动力。淮安市在发展经济的同时，需更加重视保护耕地资源，加大土地整治力度，提高土地利用效率，优化土地资源的利用与配置，确保耕地资源可持续利用。

| Abstract: | Huai′an City is located in Huanghuai Plain and Jianghuai Plain，which is a big agricultural city in the north of Jiangsu province.The study on spatial and temporal characteristics of cultivated land and its driving factors can provide guidance for ensuring food production and agricultural sustainable development.Based on land use data of 2000，2010 and 2018，spatiotemporal change characteristics of cultivated land in Huai′an City from 2000 to 2018 were analyzed by integrating land use transfer matrix，land use dynamic degree and multiple stepwise regression analysis，and driving forces were studied combined with social and economic indicators.Decreasing speed of cultivated land area has been accelerating from 2000 to 2018.Reduced area of cultivated land was mainly concentrated in the northern part of Qingjiangpu district，and transfer area between cultivated land and urban and rural industrial and mining residential land was more.Change of cultivated land was affected by economic development and income level，and tertiary industry was core driving force of cultivated land change.While developing economy，Huai′an city should pay more attention to protection of cultivated land resources，strengthen land consolidation，improve efficiency of land use，optimize utilization and allocation of land resources，and ensure sustainable utilization of cultivated land resources. |
