摘　　要：定量研究城市土地利用效益之间的耦合规律,是建立有效协调机制的关键,为城市土地利用总体规划的制订和城市的可持续发展提供重要依据。土地利用效益包括土地利用社会经济效益与生态环境效益,以哈尔滨市域为研究区,运用多指标综合评价法计算2000—2009年哈尔滨市土地利用社会经济效益与生态环境效益综合值,基于系统理论建立了二者之间的耦合模型,用耦合度来表达这两种效益之间的协调程度。结果表明:哈尔滨市土地利用效益的耦合度演化分为3个阶段,2000—2002年,土地利用效益耦合度从-30.62°快速增长到67.28°,从低级共生到协调发展,2002—2005年,耦合度从67.28°上升到85.14°,即从最佳协调状态向不甚协调状态发展。2005—2009年,耦合度为85.14°～86.85°,土地利用效益的协调程度有所下降。Quantitative study on coupling relationship between land use benefits is the key to establish effective coordination mechanisms and provide an important basis for urban land use planning and sustainable development.Land use benefit includes social economic benefit and ecological environment benefit.Harbin City was selected as the study area in this paper.The multi-index evaluation method was used to calculate comprehensive value of social economic benefit and ecological environment benefit from 2000 to 2009 of Harbin City,then the coupling between the two models through theory-based system was established and expressed this by coupling degrees between the two benefits.The results show that the evolving processes of coupling degree of land use benefits can be divided into three stages in Harbin City,the coupling degrees increased rapidly from-30.62° to 67.28° during the period of 2000—2002,the land use benefits were not very coordinated during the period of 2002—2005,the coordination extent of land use benefits decreased during the period of 2005—2009.
