摘要
以山东省为例,利用GIS技术建立了一套海水入侵灾害危险性评价信息系统。通过对多因素的综合分析,获取了各评判单元海水入侵灾害综合危险性指数,求得了各地海水入侵的平均距离,从而实现了山东省海水入侵灾害危险性区划,并能以地图或数据的形式快捷的显示处理结果。
Taking Shandong Province as an example, a risk evaluation system for the sea water invasion is established based on GIS technology. Through the comprehensive analysis of multi-factors, the comprehensive risk index of sea water invasion disaster is obtained and the average distances of sea water invasion in each region are calculated. So, sea water invasion disaster zoning of Shandong Province is made. All the processed results can be quickly displayed in the form of map and figures.
