Constitution and Application of the Regulations for Table Structure and Symbol of Water Quality Database 《水质数据库(WQDB)表结构与标识符规定》制定与应用
We established water quality information database of29 water quality test points in Panshi city based on ArcGIS, and evaluated the groundwater environment quality by using the gray clustering method. 目前地下水环境质量评价的方法很多,主要有单因子法、综合指数法、层次分析法、模糊数学法、灰色系统评价法等。
This paper introduces how to manage and inquire water quality information and plot the image of water quality information by inquiring database based on Matlab GUI; 介绍了在MatlabGUI环境下,通过访问数据库,如何对水质信息进行管理,读取水质信息,作出水质信息图像;
Realization of Water Quality Evaluation in Surface Water Database System 水质评价分析在地表水水质数据库(WQDB)系统的实现
The software comprises five modules, i. e. water quality estimation, water quantity balance calculation, chemical reagent consumption and expense calculation, water quality data management, assistant query database. 软件包括水质分析与判断,水量平衡计算,药剂消耗及费用计算,水质数据管理及辅助查询五个模块。
