摘要
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”。
A method of calculating synthetic specific yield by applying modern software tool is discussed in this paper. Based on the database of groudwater,it is introduced in detail how to process and analyse the data information from the database with MapGIS and VB language, thence the synthetic specific yield of fluctuation belt of water table and regional synthetic specific yield are obtained. It has been appiled for calulating groundwater resources of North China plain, and compiling ＂distribution graph of synthetic specific yield of fluctuation belt of groundwater in North China plain＂.
