| 摘 要： | 基于CA原理,结合GIS与RS技术,在ArcGIS平台中进行二次开发,构建了GIS-CA模型系统.以营口市为研究区域,对其城市用地扩展进行了模拟和预测.研究表明:GIS与CA集成,增强了GIS的时空动态建模功能,CA模型和GIS耦合是研究城市扩展动态模拟与预测的较为可行的研究方法；利用GIS-CA模型模拟和预测了营口城市用地变化趋势,对营口城市用地扩展模拟的结果比较合理,模拟的精度达到70％以上.

| Abstract: | At present,most of the cities in our country are at the initial stage of fast expanding,more and more construction land will be needed.Therefore a new technique should be introduced to forecast the increasing of construction land of a city,and help the managers to make reasonable decisions.Based on CA(cellular automata),and combined the techniques of GIS and RS,this paper designed a model named GIS-CA on the platform of ArcGIS,to simulate and forecast the expansion of Yingkou’s construction land.Conclusion can be classified into followings:firstly,the integration of GIS and CA is a feasible method for simulating urban expansion;secondly,by using GIS-CA,we forecast the changing tendency of urban land use of Yingkou,and the result is reasonable,and the simulation accuracy reaches 70%. |
