摘　　要：为了探讨如何实现建设用地的科学开发,以江苏省103个县域单元为研究对象,基于2017年土地变更调查数据,采用加权求和、熵权TOPSIS和模糊综合评价法,从建设用地开发程度、开发效益和开发潜力3方面构建评价指标体系,并应用耦合协调度模型分析三者之间的协调度。结果表明:(1)江苏省建设用地开发程度、开发效益和开发潜力的空间差异显著,苏南各县区建设用地开发综合指数最高,苏中次之,苏北普遍较低;(2)103个县域单元的建设用地开发均处于协同演进状态,开发程度、效益和潜力三者耦合协调指数较高,并呈现由南到北依次递减的空间分异规律;(3)两两维度间的协调性差异较大,建设用地开发效益和开发潜力之间的协调性最佳,开发程度和开发效益、开发程度和开发潜力之间的协调性稍弱,两两间的耦合协调空间分异特征与总体协调性分布相对一致。总之,江苏省建设用地开发情况由优到劣排序大致为苏南>苏中>苏北,应参考各地区建设用地开发现状和自身开发潜力评估结果,因地制宜对土地规划政策进行调整,从而为优化国土空间格局提供科学参考。In order to explore how to realize the scientific development of construction land,taking 103 counties units in Jiangsu Province as the research objects,based on the land change survey data in 2017,using weighted sum,entropy weight TOPSIS and fuzzy comprehensive evaluation method,we constructed an evaluation index system from three aspects of construction land development degree,development benefit and development potential,and analyzed the coordination degree among the three by using the coupling coordination degree model.The results show that:(1)the spatial differences of construction land development degree,benefit and potential in Jiangsu Province are significant;the comprehensive index of land development in southern Jiangsu Province is the highest,followed by the middle of Jiangsu Province,but the northern Jiangsu Province is generally low;(2)the construction land development in 103 county units in Jiangsu Province belongs to the state of collaborative evolution;the coupling coordination index of construction development degree,benefit and potential is high;the index shows the spatial differentiation pattern of decreasing from south to north;(3)the coordination between the two is quite different;the coordination between the development benefit and development potential of construction land is the best,while the coordination between the development degree and the development benefit,the development degree and the development potential is slightly weak;the spatial differentiation characteristics of coupling coordination between the two are relatively consistent with the overall coordination distribution.In conclusion,the development situation of construction land in Jiangsu Province from good to bad levels is in the order:southern Jiangsu Province>middle of Jiangsu Province>northern Jiangsu Province.We should adjust the land planning policy according to local conditions,so as to provide scientific reference for optimizing the land spatial pattern by referring to the current situation of construction land deve
