摘　　要：分析了生态环境影响评价指标体系的建立方法,并在此基础上,探讨了以Arc/Info为平台,使用矢量数据建立生态环境影响评价模型的方法,并与使用栅格数据的评价模型进行了对比分析,得出使用矢量数据的评价模型具有运算结果精确度高、修改方便、效率高、操作过程简单等优点。This paper discussed the establishment of method for the index system of ecological environment impact assessment. Then it studied the methods of building ecological environment impact assessment model using vector data, with Arc/Info as platform. Contrastive analysis was conducted between this model and that of raster-based model. It concluded that the vector- based model showed more advantages such as high accuracy, convenience for modification, high efficiency, simple operation etc.
