Based On Mapx County Air Environmental Information System Development And Research

The geography information system (GIS) is the technique system which carries on collecting, storing, managing, operating, analyzing, showing and describing the space data on the support of calculator software & hardware. The ability of data integration, simulation and evaluation is technical advantage of GIS. Environmental control through the GIS is an important trend on the current.Based on the GIS, on the background of the atmosphere environment of Qi jiang County, it is established the county atmosphere environment information system according to the MapX. The system can complete the renewal, result inquirement, analysis and graphics management of the normal atmosphere quality in Qi jiang.It is realized the management and visualization of various atmosphere environment data, the special analysis of various pollutant and the valuation of atmosphere quality in the district carried on the management of data of polluting source and monitor point. It provides the technique support and decision basis for governor and decision maker The development of system is chosen two kinds of development methods matching the system terrace of the geography information and geography information system control. On the basis of mapinfo7.0, it has completed map numeral and the establishment of space database. On the basis of Basic6.0, function of the connection of attribute & space data and the space analysis of the data is completed by MapX control. The System can be used in the LAN or the World Wide Web, data sharing and accelerating the flow of information can bing ture.First, it is discussed the domestic and international development condition and hot research of environment information system, objected the constitute of environment information system, development terrace, development principle and module type GIS principle, introduced the development tool MapX. Then, it is analyzed air pollution characteristic of Qi jiang county. In the end, it is discussed the design of the system, the establishment of database, main function and technique contents. The system comes to anticipant purpose and the request through the data examination. It is satisfied the daily demand of environment information governor. So, the system has strong operability and important practical value.
