The Design and Implement of River Valley Water Pollution Prevention and Cure GIS System

摘要

The planning of river valley water pollution prevention and cure involves in much spatial information and attribute information, so it needs to build spatial assistance decision support system which includes GIS technologies, mathematics model technologies and the leaders' decision and experts' knowledge. The system can realize information sciencilization, modernlization and standardization. This paper has discussed a system method to build GIS system for river valley water pollution prevention and cure planning, and realized an instance research on hanjiang river valley. This system includes spatial geographical location information, water information and human being and economical information of the whole valley and main cities and towns in the valley. the model-base system includes river's 1-D model, river's 2-D model, artificial neural network water quality appraise model and etc. The method-base mainly provide some essential algorithm for those models. It is a very important step to select appropriate models based on the practical need and information and manpower which can be provided. The knowledge-base provides effective assistance decision support for the planning of water pollution prevention and cure.
