摘要
借助地理信息系统利用离散点插值扩展法对大连湾海域的水质污染空间分布情况进行了环境评价，通过计算污染区域的面积得出了各类水质的海域空间分布，克服了以往逐点评价海域的片面性。
This article assesses the quality of sea water in Dalian Bay by combining geographical information system (GIS)with insert data between scattered dots. and find out the distribution of pollutant in space,overcome the shortcoming of assessing some area with calculating dot by dot.This way has a great meaning for controlling pollutant in sea.
