该文探讨了一种应用现代软件工具计算综合给水度的方法,即以地下水数据库为基础,用MapGIS的空间分析功能和VB语言编程来处理和分析提取的数据资料,从而求得水位变动带综合给水度和区域综合给水度。该方法在“华北平原地下水资源可持续利用调查评价”项目的水资源计算中得到应用,并计算和编制了“华北平原地下水变动带给水度分布图”。
This paper explores a method of calculating the integrated water supply using modern software tools, that is, based on the groundwater database, using the spatial analysis function of MapGIS and VB language programming to process and analyze the extracted data, Water supply and regional integrated water supply. The method has been applied to the calculation of water resources in the project of “Investigation and Evaluation of Groundwater Resources Sustainable Utilization in North China Plain” and the “distribution map of groundwater change in North China Plain” has been calculated and compiled.
