Study of setting up County Forest Resource Management Information system based on Web and GIS As information age is coming, a serial of strategic measures, such as digital earth and digital forestry and so on, are brought into effect, moreover network technology becomes maturing and has been used widely and widely, all forest management information system can be integrated seamlessly by network technology, WebGIS can be used to publish data to web, which all can realize forest resource information to be shared, transferred, computed through the network, so all units and researchers’ recollecting data and rebuilding information is avoided, and all data which have been obtained can be used sufficiently; at the same time, forest resource information system based on web provides a new way for the public to obtain forest information, concern about forestry, and participate in forestry decision, which arouse the public to accelerate forestry healthy developing and environment improving. Setting up forest resource information system based on network and GIS can resolve the above problems in forest resource management, this kind of system is development trend [6]. 3. Research Region Introducton Ningshan county is located in south of Shanxi province, the forest units in Ningshan county are classified subject-units and unsubject-units, subject-units like forestry farms, which are managed by contractor or by collectivity; unsubject-units like Huoditang farm, Ningdong forestry bureau and lots of mine etc.(Fig. 1 ). This research selects investigating data, stock map, relief map etc. of Huoditang farm and Ningdong forestry bureau in 1992 as test data  Fig 1 Ningshan country foresty unit relation model 4. System Project 4.1 System Development Model and GIS Developing Software The development methods of thematic GIS are three [7], namely: independence development, simply-secondary development and integrated secondary development. independence development doesn’t depend on any tool software from data gathering, editor treatment, data analysis and result exporting, all algorithms are designed independently by the developer, it is too hard; simply-secondary development is development based on language which GIS software has, the development is always not satisfied because the language is not convenient to develop; Integrated secondary development is a trend to develop thematic GIS, It can not only integrate the function of GIS, such as management spatial data and strong spatial analysis but also take advantage of the high efficiency & convenience of the OOL, so it can improve highly the efficiency, moreover the function of system is strong and the interface of system is beautiful & friendly. This research is based on MapXtreme for NT Version at B/S model. MapXtreme, WebGIS software, is WebGIS map application server of MapInfo Company which main technology is Active component of MapX (Fig 2). The system integrates the function of MapInfo and MapX with Asp and script language, so administrator only need install MapXtreme on Web server, users can request MapXtreme and use the function of MapXtreme[8][9];C/S model is developed with OOL Delphi. 4.2 System Configuration 4.2.1 System Software (1) Server Web/ application server software configuration Operation system: windows 2000 Advance server, Web publishing and site management: IIS 5.0 Map application server: MapXtreme For NT 3.0 version (2) Data Server Software Configuration Operation system: windows 2000 Advance server Database management system: Microsoft SQL Server 2000 Map data server: MapXtreme NT 3.0 version Client software configuration Operation system: Win98/win2000/winxp Browser:Microsoft IE/Netscape

MapXtremer application model 4.2.2 System Hardware Configuration Server: 512M memory, 40G hard disk, doubles CPU 4.2.3 Network Environment With the fast development of the computer technology, word wide web enter every home, the public can browse web through dialing the phone, so shared data can be obtained easily; with the prevalence of ADSL broadband, broadband provides a better way to visit the database. Forest sub-unit can browse web through ADSL technology. |
