Abstract


This thesis focuses on the current water quality data quality management and technical personnel to rely on long-term accumulation of experience , lack of modern methods and means of the issue , trying to establish an environmental management system to achieve water quality data for the batch audits and management , as well as to achieve the dynamic evaluation of water quality . The use of water quality physical and chemical concepts and mathematical statistics methods, combined with study area pollution characteristics , the establishment of water quality indicators relationship between test water quality indicators to time test and water quality spatial relationship test methods for water quality data quality management to provide reasonable inspection methods and means. In Delphi and SQL2000 database development platform, combined with the secondary development of MapX control ; reasonableness test methods in the data based on the research , the establishment of a common set of water quality monitoring data checking management and water quality evaluation of water environment management system . Water environment management system design and development, management and monitoring tasks were established water environment assessment system model , water quality monitoring data will be checked against the various functional modules are integrated into the monitoring task management system model, the evaluation of different objects by the Water Quality Assessment system model to achieve. Reasonableness of the data during the inspection , using GIS thematic maps and changes in water quality trend test the correctness of human judgment . Reasonableness test in the data , based on the reasonable evaluation of water quality data . Evaluation results to report in the form of thematic maps and GIS output . In this thesis, the Taihu Lake Basin , water quality data verified the reasonableness test the feasibility and practicality of water environment management system .
