摘　　要：土地的高效利用和配置优化是城市化进程的现实需求,探究如何提高土地利用综合效益,从而实现对地区土地利用可持发展具有重要意义。从经济、社会、生态环境效益三个子系统构建土地利用效益评价指标体系,利用熵值法探究海峡西岸城市群2008—2017年的土地利用效益及其时空演化过程和耦合协调关系,进一步识别限制各城市耦合协调关系提升的主要因素。结果表明(:1)海峡西岸城市群城市土地利用综合效益存在持续上升的时序特征,空间上表现为"东高西低",高效益单元主要分布于沿海门户城市及中心城市,且趋于聚集,低值单元主要长期分布于内陆城市和南部沿海城市,且范围不断缩减。(2)城市土地利用经济效益在时序上表现出持续上升的特征,空间上表现为"中高西低",西部低值区范围明显变小;社会效益小幅增长,中东部形成"环状"中效益区;生态效益整体较低,中部低效益区范围扩张显著。(3)各城市土地利用"经济-社会-生态环境"效益耦合协调度呈不同程度增长趋势,近年以协调发展为主,耦合协调程度表现出由沿海向内陆城市递减的空间异质性,土地利用耦合协调发展主要受复合因素制约。It is of great significance to explore how to improve the comprehensive benefits of land use so as to realize sustainable development of regional land use. In this paper, a land use benefit evaluation index system is constructed from three subsystems of economic, social and ecological environmental benefits. The entropy method is used to explore the land use benefits of urban agglomeration on the west coast of the strait from 2008 to 2017, as well as its spatiotemporal evolution process and coupling and coordination relationship, so as to further identify the main factors that limit the improvement of coupling and coordination relationship among cities. Results show that, in the west coast urban agglomeration, high benefit units of comprehensive benefit of land use are mainly located in the center of the coastal gateway cities and city,and tend to be gathered, low units mainly gathered in the inland city and the southern coastal cities, and over the studying period, the number of low units had been shrinking. The economic benefits, social benefits and ecological benefit of urban land use showed continuous rise over time. The spatial patterns of the benefits were "high in the middle, and low in the west". The coupling and coordination degree of "economic-social-ecological environment" benefits of land use showed a trend of different degrees of growth. In recent years, the coupling and coordination degree had been increased, but the spatial heterogeneity of decreasing had shifted from coastal cities to inland cities, and the coupling and coordination development of land use is mainly restricted by complex factors.
