摘　　要：通过文献查阅和专家咨询方式,选取生态适宜度分析指标,基于规划区土地的不同利用功能,运用ArcGIS9.0系统对区域的规划图进行数字化,实现了评价过程的可视化;利用GIS中栅格运算功能,将不同指标赋予不同属性的图层进行叠加运算,得到不同颜色的区域,根据评价结果的分类原则,进行重新分类,将区域分成不同颜色表示区域开发的生态适宜程度。利用评价结果对规划区土地进行用地功能调整,可以为开发区的合理规划提供决策依据。Through literature reviewing and expert consultation, selecting ecological suitability indicators, based on different land utilization functions of planning area, digitization was conducted on planning map by using AreGIS9.0 system, visualization of assessn^nt course was real- ized; using grid computing function in GIS, images of various indicators endowed with different properties were calculated, different color＇ s re- gion were obtained. According to classification principle of evaluation results, different color indicate ecological suitability degree. Using evalua- tion results to adjust land use can provide decision-making basis for proper planning of development area.
