| 摘 要： | 对地理信息系统（Geographic Information System，GIS）技术在地表水环境影响评价中的应用进行了系统分析，指出了应用GIS的技术优势。通过实例研究，提出了基于GIS的区域地表水环境影响评价的方法步骤。在环境监测数据的基础上，利用计算机软件ArcView对BOD5和COD两个评价参数的监测值在水域中的空间分布进行分析，绘制区域等值线，结合地表水评价标准，进行水质评价，确定不同等级水质的空间分布区域。最后对应用GIS应注意的问题进行了分析。

| Abstract: | The application of geographic information system(GIS)technology in environment impact assessment of surface water was analyzed systematically,and its advantages were pointed out.By case study,the steps for environment impact assessment based on GIS were put forward.The computer software ArcView was used to analyze the spatial distribution of the two assessment parameters of BOD_5?COD in water bodies with environmental monitoring data,and to draw regional isolines.The water quality was assessed according to Chinese Surface Water Standards and the spatial distribution regions with different grade of water quality were confirmed.At the end,the key issues for GIS application were narrated. |
