摘　　要：在构建山东省城市土地利用效益综合评价指标体系的基础上,采用熵值法确定各指标权重,运用综合指数模型对山东省17个地级市2006—2016年的土地利用综合效益的时序特征进行研究,用耦合协调度模型对各城市的土地利用效益协调度的空间差异性进行分析。结果表明,各城市在2006—2016年土地利用程度相差较大,土地利用综合效益呈现出高、中、低的分层局面且在时间上展现出不同的发展趋势,其差异性主要表现在与经济有关的指标上;各城市土地利用社会经济效益和生态环境效益之间的耦合协调度差异很大,其中协调度最高的是青岛市,达0.85,协调度最低的是菏泽市,仅为0.42;在空间上,山东省东部沿海城市的协调度较高,西部内陆城市的协调度相对较低。Based on the construction of the comprehensive evaluation index system of urban land use efficiency in Shandong province,the weight of each index was determined by entropy method.The time sequence characteristics of the comprehensive land use efficien⁃cy of 17 prefectural-level cities in Shandong province from 2006 to 2016 were studied by using the comprehensive index model,and the spatial difference of the coordination degree of land use efficiency in each city was analyzed by using the coupling coordination model.The results showed that the land use degree of each city was quite different from 2006 to 2016,and the comprehensive land use benefit presented the situation of“high,middle and low”stratification and showed different development trends in time,and the differ⁃ences were mainly reflected in the indicators related to economy.The coupling coordination degree between the social and economic benefits of land use and the ecological and environmental benefits of each city was very different.Among them,Qingdao city had the highest coordination degree,reaching 0.85,while Heze city had the lowest coordination degree,only 0.42.In terms of space,the coor⁃dination degree of eastern coastal cities of Shandong was relatively high,and that of western inland cities was relatively low.
