A Study On DianChi Basin Water Pollution Controlling Simulation System

The wate envirInnen of DianChi Basin is a gian system, in thes paPe,SySteIn SWation and GIS are aPplied tO study the POllution of the system and aset of comPuter sAnulation syStem is deve1oped called DianChi SedationSySteIn. The sdriulation syStem is of great prachtal vaIue, and by means ofsedating the whole wate environment and qUantitative analysis on the basis ofexhaustive data, the rule of the distribution of Waer qUanity and the condition ofwater quality of DianChi Basin is gOt. Therefore the sedation system lay thefotmdation of utilizing water resouree rationally and cothelling water pollutionNely for the decision makr.Went ndysis is the basis of the development of a software system,While system design is the bridge to conneCt the goal with the bolemenboon. Inthe paper, both sides are discussed in detail. Data is the basis of sAnulation.relational data model and ~al datu modl are described, and itS realhation isdiscussed, tOO. The author also solve the PrOblem of managing sPatial dain andPrler data consistCny by using ArcSDE. Besides, it is bortan tO recotwthe for of data ffies in DianChi Sedation System..The Water source SUbsystem is the tw pat of the whole system. andalso lay the foUndaon for wate souree PrOgrannning. The water resourceMutin course is djscussed and the water controlling rule is focused on thereedW W "IImer boe" and "Outer W' and ny tO ashieve it.New tWqUeS will be adOPted in the process of developing, the aUthrintodUed theIn and aiso give the readr a vista of the W of DianChiSinnilthen SysteIn.
