The Design And Development Of The System For Regional Water Resource Management That Based On Webgis

As a kind of special mine, water resource is a regeneration resource. However the renovated and compensatory water from nature is limited in regional unit time. Meanwhile, the water resource is a fundamental element of the ecological environment. The rational management of water resource is an important measure of protection and improvement of ecological environment.Our country is the one of the 50 nations and areas that the most poverty of water resource of the world, the average person possession of water is only 2500 m3, just as the one quarter of the world's. Shanxi is a quite shortage of water resource in our country. The average person possession of water is only 466 m , just as 17% of our nation's, 4% of the world's. With the highly economical development in our nation, the need for water is greatly exceedingother resource. The rational exploiture and continual utilization became the important precondition of continual development of country economy , then get the highly regard increasingly. Therefore, duly and dynamic knowing and holding the information of regional water resource and conferring the variable tendency of regional water resource in sometime has the vital meaning in dynamic management for regional water resource, protection in continual economical development.With a plenty of investigation and research, the paper focused on the limitation of the conventional water resource management, combined the building of the management information system for Zhangze reservoir in ShanXi, and then chose the experimental unit in Zhangze drainage area for applying research. Based on Internet support, through the technology of GIS, database ,Asp variable network and so on , combined the elements of geologic, physiognomy, hydrological and otherwise , used the gigantic information and predominance of freedom in terrain of Internet, breakthrough the conventional limitation, realized the long-distance and interact data access in client, built the netlized , digitalized ,intellectualized decision-making system which combined the data process and manage. Furthermore, it integrated the hydrological data, fundamental geographical data, weather data into one database, linked the data from database and model of drainage area hydrology, processed the scene analysis and hydrological systematic simulation. The system is used to refresh, inspect and forecast the information of regional water resource from web net, realized variable management of water resource, made the availability attempt for the informationalization, mobilization, modernization of the water resource management.
