摘　　要：实现社会经济效益和生态环境效益的均衡发展,是全面协调可持续发展的必然要求。在深入分析土地利用效益评价等有关理论的基础上,结合武汉市土地利用现状,从土地产出的综合效益均衡角度,形成了由社会经济效益和生态环境效益两个子系统构成的评价指标体系,采用主成分分析法确定各指标权重,对武汉市土地利用社会经济效益和生态环境效益进行评价;再构建武汉市土地利用的社会经济效益与生态环境效益的耦合模型,辨识两者之间的协调关系,分析两者之间的协调程度。研究结果显示,1996—2010年武汉市土地利用社会经济效益与生态环境效益均呈上升态势,其中社会经济效益表现出起点低、增幅大、速度快的特征,而生态环境效益则呈现出起点较高,增幅较大,在波动中稳定上升的特点。土地利用社会经济和生态环境效益耦合度评价结果显示,在1996—2010年,武汉市城市土地利用社会经济效益与生态环境效益的耦合演化进程近似于对数曲线,从形成初期的不协调至激烈博弈后的利益分化,之后经历相对最佳协调后,又逐渐向不协调发展并呈现新的演化特点。Enhancing the land use comprehensive benefits is an inevitable requirement of sustainable develop- ment. Based on the data of land use and socio economic development in Wuhan City during the period from 1996 to 2010, the evaluation weight system of socio-economic and eco-environment benefits was established. And the weight of each indicator was evaluated using principal component analysis （PCA）, and then the so- cio-economic and eco-environment benefits of land use from 1996 to 2010 were evaluated. In order to deter- mine the coordinated degree between socio-economic and eco-environmental benefits systems, a coupling model on two systems was built by the method of system science theory. The result showed that land use so- cio-economic benefits and eco-environment efficiency had increased in Wuhan City during the period from 1996 to 2010. The socio-economic benefits underwent the process of low beginning, fast speed and large in- crease. However, the trend of eco-environment benefits showed the process of high beginning, and the process of larger increases and steady fluctuation rise. The results of coupling degree showed that the trend of coupling degree was similar to a logarithmic curve in Wuhan from 1996 to 2010, which differentiated from the interests of the early formation of incongruity to the intense game, and then experienced relatively coordi- nation, gradually uncoordinated development and presented a new evolutionary feature.
