摘　　要： 围绕保障土地资源可持续利用的目标,基于主成分分析法和协调发展模型,利用广州市1995-2007年统计数据对其土地利用与生态环境协调发展状况进行了实证分析。结果表明：研究期间广州市土地利用与生态环境以强势协调发展模式为主,总体经历了土地利用滞后型强势协调发展模式到土地利用超前型强势协调发展模式再到土地利用超前型弱势协调发展模式的演化过程;土地利用与生态环境的动态协调度整体呈现出下降的态势,二者逐渐在偏离协调发展的轨迹;最后提出了相关政策建议及不足之处。 According to the target of the sustainable utilization of land resources,this paper conducted an empirical investigation between land use and eco-environment coordinated development situation based on the method of principal component analysis and the coordinated development model,utilizing annual data of Guangzhou from 1995 to 2007.The results showed that： the dominant model of the studied period was strong-coordinated,changed from the lagging land use period to the advancing land use period of strong-coordinated development model and then the land use advancing weak-coordinated development model;the dynamic coordinated degree between them showed the declining trend as a whole,and both gradually deviated from the track of coordinated development;finally,relevant suggestions and the defect were proposed.
