Study On Chaharyouyihouqi Ecological Protection Engineering Information System Based On 3S

Today "3S" technology in all aspects of society and economy is an increasing role, which is changing our work and life. In order to adapt to the requirements of environmental protection development in the banners and counties, and ChaHaryouyihouqi practical needs of ecological protection engineering, establish ChaHaryouyihouqi ecological protection engineering information system what has become urgent."ChaHaryouyihouqi ecological protection engineering information system"can be divided into three parts: data processing, system designing, and programming. Previous work is to all sorts of data gathering, collection, processing, arranging, analyzing, classifying, storing, etc; Mid-term work is geographical spatial database was established by domestic GIS software super map, including basic geographic information platform and various professional geographic information platform, and using this database software SQL Server 2005 attribute database and document picture database were established, the processing and the processed, audio and video database stored in a database; Finally object oriented programming language Visual Basic 6.0 will be used and through Superman Object5.2 controls will be called by programming, and Server2005 database will be lilted to friendly interface SQL, at last the whole system compilation will be completed. System realizes the spatial data and attribute data connection integrated visualization, the storage of electronic document, picture, audio and video data, of basic operation and editing functions electronic map, data classification calls and correlation of calls, all kinds of data query, statistics, analysis, management, and so on. It Improve the management of ecological engineering of ChaHaryouyihouqi, to provide scientific basis for the government decisions of Beijing and Tianjin Sandstorm Source Control Projects. The system has accomplished the 2001 to 2010 years of ecological protection engineering data acquisition, processing, analysis and management; Using GPS and remote sensing monitor the ecological project engineering, meanwhile, combining the engineering data examine the completion of the ecological engineering, and whether there will be a repeat work; Using multiple buffer and superposition analysis predict desertification dangerous area; Different environment special charts production have been completed, what provides basis and direction for ChaHaryouyihouqi scientific and reasonable, protection and utilization of the sustainability of ecological environment and resources, in the mean time, what provides the reference information toChaHaryouyihouqi other project.
