摘　　要：耕地作为人类不可替代的自然资源的基础,其数量和质量的特性决定着一个国家或地区社会经济的可持续发展.通过对重庆都市区(1996-2004年)耕地面积变化与经济发展的相关性分析,将都市区分为三种类型:①经济增长超前,耕地减少滞后;②经济增长与耕地减少同步;③经济增长,耕地减少超前.总体上,都市区的经济增长模式仍属于资源消耗型.重庆都市区耕地面积减少量与GDP增加量比值的差别较大,说明被转用的那部分耕地的利用效益在不同的区域之间存在较大的差异.Cultivated land was the base of indispensable natural resources, its quantity and quality decided the sustainable development of an county or disti＇ict.
