摘　　要：高原湖滨区域经济可持续发展及城市化必须控制城镇村建设用地规模,节约集约土地,保留足够的生态用地和绿色空间,才能维持湖泊流域生态系统的良性循环。以滇池流域为例,通过生态约束下的城市扩张与土地集约利用情景模式的理论构架,设计了自然发展、生态约束、集约利用发展和生态约束下的集约利用发展四种城镇村用地模式,运用SLEUTH模型进行了CA情景模拟实证研究。研究结果表明:生态约束下的集约利用发展模式是高原湖泊流域城镇村土地集约利用和生态环境保护相协调的的最佳模式,并给出了滇池流域城镇村发展相关政策建议,从土地利用角度探索了高原湖滨城市化地区经济发展与湖泊生态保护的新途径。The sustainable development of regional economy and urbanization in Plateau Lake basins must limit the scale of City-Town- Village（CTV）, conservation and intensive land, keep the ecological land and green space, in order to maintain a sound ecological system of Plateau Lake. In this paper, taking Dianchi River as an example, through constructing a theory framework that the ecological constraints of urban sprawl and land intensive use model, designning four scenario model of CTV＇ land use：the natural development, ecological constraints, intensive development, and the ecological-intensive development , using SLEUTH model to make empirical study. The results shnw： the ecological-intensive development scenario model is the optimal model, which coordinates the CTV＇ land intensive use and protection of the ecological environment in a plateau lake basins , and presents the relevant policy suggestions for the developnlent of CTV in Dianchi basin. From the view of land use to explore a new approach of economic development and ecological protection in plateau lake urbanizing area.
