【摘要】 结合漓江的水文和水质特点,综合利用数学建模、V isualBasic高级语言编程、AC-CESS数据库技术、图形图像处理技术,初步开发了漓江流域水污染控制软件系统.该软件系统包括电子地图平台、水质模拟模块和水环境容量计算模块.针对中小型河流的特点,选择Streeter-Phelps模型微分式的托曼(Thomas)修正式,建立了漓江水质模型.水环境容量的计算同时考虑稀释、迁移和净化作用.该软件系统可为漓江流域水污染控制规划、决策、设计提供科学合理的依据,对其他流域的水污染控制提供借鉴.尽管软件功能尚显单一,但由于该系统提供了可自由拓展的接口,因此可根据实际需要随时添加相应的模块,使该软件系统在实际应用过程中不断得以完善,可极大提高流域水污染控制的效率和管理水平.更多还原

【Abstract】 Based on the water quality and hydrologic characteristics of the Lijiang River,a water pollution control software is developed by math analysis and model,Visual Basic software,ACCESS database technology,graph and image treatment technology.The software includes an electronic map interface,a water quality simulation module and a water environment capacity calculation module.The water quality simulation module is based on Thomas revision of the Streeter-Phelps model.The water environment capacity calculation module includes dilution,transportation and purification.This software is useful for the management and design of water pollution control in the Lijiang valley,as well as in other valleys.Although the function of this software is simple,it can promote the efficiency of water management of valley because it can be developed according to the changed situation.更多还原
