【摘要】 本文以干旱寒冷地区草型富营养化湖泊乌梁素海作为研究对象,针对乌梁素海日益严重的污染现状以及管理现状,以管理信息系统(MIS)理论、地理信息系统(GIS)理论和数据库系统(DBS)理论为依据,结合较成熟的水质评价理论、趋势分析模型和水质模型,借鉴国内外水质管理的成功经验,分析湖泊水质管理工作需求,遵循科学性、实用性、统一性、扩展性等设计原则,以面向对象的程序设计语言Visual Basic6.0、集成开发数据库Access2003和地理信息系统MAPGIS6.6为工具,建立基于GIS的乌梁素海水环境管理评价信息系统。本系统以乌梁素海2006年实测的野外及室内实验数据(22个海上取水采样点的20个物理指标、化学指标、生物指标)为基础数据,用Access2003建立水质指标数据库;以VB6.0为开发工具,集成水质现状评价模型(指数评价模型,模糊综合评价模型);集成MAPGIS的部分图形编辑功能,建立乌梁素海水环境管理评价信息系统。使其具有数据浏览、数据查询、数据管理、水质现状评价、GIS等功能。并应用水质评价模块对2006年5～10月的海上水质进行了模糊综合评价,对总N、总P进行了DTM分析。根据评价及分析结果为湖泊管理监控部门提供切实可行的决策支持系统。更多还原

【Abstract】 Taken plant-type eutrophic Wuliangsuhai lake as a research object in drought and cold area,based on management information system(MIS)theory、geography information system(GIS)theory、database system(DBS)theory,combined with skilled water quality assessment theory、trend analysis model and water quality model, referenced domestic and abroad successful experience of water quality management,analyzed work need of lake water quality management,comply with design principle of science、practicability、unity、expansibility,using object-oriented Visual Basic 6.0,Access 2003,Mapgis 6.6,the thesis established water environmental management and assessment information system in accordance with the condition of serious water pollution and management in Wuliangsuhai lake.Based on the data of measured and experiment in 2006 in Wuliangsuhai lake(22 monitoring points data of physical indexes、chemical indexes、biologic indexes),established water quality indexes database; taken VB6.0 as the development kit,integrated water quality present condition assessment model(index assessment model, fuzzy assessment model);integrated mapgis 6.6 part graphics compile function,finally established water environmental management and assessment information system that possesses the functions of date scan,date query,date management,water quality present condition assessment and GIS etc.The thesis integrated with database、GIS、water quality assessment model,developed water environmental management and assessment information system which is same with wuliagsuhai lake and achieved all kinds of functions modules.Then synthetically assessed water sample of in 2006 in Wuliangsuhai lake by water quality assessment module and analysed N,P element with DTM.The thesis can offer practical feasible decision-making support system for lake management departments based the assessment and analysis result.更多还原
