Design Of The Drought-relief Decision Support System Of ChuZhou

In recent years, with the increasing of population and the development of industry and agriculture.the contradiction between water supply and need become more and more severity. Rapidly collect the information,accurately evaluate the drought degree and make reasonable decision become more and more important. The drought-relief decision support system is designed to provide support in the drought-relief decision.The DRDSS system collect various kinds of data from different areas through the computer network . do analysis according to the mathematics model which already Established and make decision to relieve the drought according to the actual circumstance. The DRDSS system includes the following contents: Geographic Information System,which storage and handling of the Geographic data .Database System, which storage and processing of the information about the drought.The drought assessment subsystem, which do analysis of drought situation According to its well-established model, the system interface,which offer tools to users to operate the system.This article expatiates the design theory ,the contents, the develop tool and the design philosophy of this four subsystem .it also supplies some source code of this system.
