中文摘要：[目的]基于经济社会发展转型视角,探究长江中游地区土地利用变化的总体特征、过程特征和轨迹特征.[方法]通过分析变化幅度、变化速度和地学信息图谱等特征.[结果](1)2000-2018年,长江中游地区经济社会发展可划分为"由初级产品生产阶段Ⅱ期向工业化中期转型,城镇化缓慢发展与人口严重外流期"和"由工业化中期向工业化后期转型,城镇化稳步发展与人口持续回流期"2大阶段.(2)就变化总体特征而言,以耕地面积持续减少,水域和建设用地面积持续增加,林地、草地、湿地面积明显减少,未利用地面积保持相对稳定为主.(3)就变化过程特征而言,2000-2010年以耕地和林地相互转化,耕地向建设用地和水域转化,以及水域向湿地转化为主;2010-2018年以耕地和建设用地相互转化,林地向建设用地和耕地转化,以及湿地向水域转化为主.(4)就变化轨迹特征而言,以前期变化型为主,后期变化型和反复变化型次之,持续变化型所占比例较小.[结论]长江中游地区土地利用变化阶段性特征明显,主要表现为不同经济社会转型过程中由区域内不同土地利用类型转化规模与方向所导致的土地利用数量与空间结构变化.

外文标题：Stages Division and Characteristics Measurement of Land Use Change in the Middle Reaches of the Yangtze River

外文摘要：[Objective]From the perspective of socioeconomic development transition,this study aims to explores the spatiotemporal characteristics of land use change in the middle reaches of the Yangtze River(MRYR).[Methods]The method of change range and change speed of land use change,as well as geographical information map were employed.[Results](1)The socioeconomic development stage of the MRYR have undergone two transition processes during 2000-2018.The first is from the primary production stage Ⅱ to the middle industrialization stage,with slow growth of urbanization and serious outflow of population.The second is from the middle industrialization stage to the late industrialization stage,with steady growth of urbanization and continuous return of population.(2)In terms of overall characteristics,the cultivated land area continues to decrease,the water area and construction land area continue to increase,the woodland,grassland and wetland area obviously decrease,and the unused land area remains relatively stable.(3)In terms of process characteristics,in 2000-2010,cultivated land and forest land were transformed into each other,cultivated land into construction land and water area,and water area into wetland were the main change types.In 2010-2018,cultivated land and construction land were transformed into each other,forest land into construction land and cultivated land,and wetland into water area were the main change types.(4)In terms of trajectory characteristics,the early change type is the main type,followed by the late change type and repeated change type,and the proportion of continuous change type is small.[Conclusion]The stage characteristics of land use change in the MRYR are obvious,which is manifested in the change of land use quantitative and spatial structure caused by the scale and direction of transformation between different land use types in different transition periods of socioeconomic development.
