Research And Application Of Data Fusion Technique And GIS In Management Information System Of Water Quality

Water quality assessment is the brief name of water environment quantity assessment.Its purpose is according to use and physics, chemistries,biology of character of water.According to data fusion, quality standard and method of assessment, Proceed to assess to water quality with method of qualitative analysis or quantitative analysis.The information fusion is direction of a new system science research that it spreads modern information technique and synthesizes many subjects to be invented.Because it already has emerged vast valid application and theories foreground at the military and public realm, the domestic and international scholar and numerous actual the expert in engineering realm have paid attention to it.lt involves mathematics tool, research method, existent problem and the way of thinking of these problemses are all a very hot scholarship research realm.The geography information system( GIS) is an new technique subject.it is a brink subject cross the geoscience,informat -ion science and space science, is a computer technique system to appropriation to handles geography space information .It can gather, store , analysis and rea ppear the space information availably, in order to search,analyzes the space geography inform -ation fast, attain the purpose that proceed to describe, imitate ,forecast to the research object.This text is to synthesize above every kind of technique. Assess water quality primarily with information fusion direction, binding assessment result data to property data of GIS, making use of Delphi7.0 and MapX develop tool establishes water quality management information system.The full text is divided into five main chapters, the contents is as follows:Chapter one A general outline is a research to introduce this thesis background to say and a technique for applying to all.Chapter two Water quality fusion and assessment, divide two section, have primarily: Water quality assessment method to summarize;Data fusion technique, the in common use data fusion arithmetic at application of water quality assessment.Chapter three introduced the geography information system( GIS) technique, having primarily below of three section:GIS general outline and current in common use software tool;GIS basic theories. The Component technique of MapX.Chapter four GIS was applied to water quality management information system.End part, to the summary of the full text and from now on the outlook that work.
