As slogan of digital earth is being brought out, and strategic measure, digital forestry is being brought into effect, people concern about forestry development more and more; but forest management of our country presently can not meet the need of setting up the mechanism of modern production of our country forestry, the methods of memory, query, statistics, analysis and share forest resource information also can’t satisfy the forestry production, management and macroscopical decision [1] On the other hand, a lot of methods have already been proved ripper with information technology development; for exmple, the Land Grading Information System of Zhengjiang City based on component GIS[2],state water enviroement information system based on WebGIS [3],Dengguang, Leizhangyu, workers of forestry sciense institute, study the application of WebGIS in forest resource information share and set up the information system based on WebGIS [4], we can use those methods to set up forest resource management which can meet the need of forest resource management in new age. On this background, this research selects Ningshan County as representative region in order to set up forest resource management information system base on WEB and GIS to meet the need of forest management today.
1. The Necessity of setting up County Forest Resource Management Information system based on WEB and GIS
Forest resource is the base resource of forestry, it is key thing for forestry to realize forest sustainable development, but there are some problems in forest resource management.
- The memory medium of Forest resource attribution data and map is paper, so it is very slowly to update data and the information’s credibility and veracity is bad, it is hard to compute, manage and share data. The value of data can not be used completely.
-
Forest resource management information system based on file or database technology can not meet the need of modern forest resource management.
The traditional information system based on artificial management or file technology didn’t satisfy the modern enormous data management, the system based on database technology can query, insert, delete, and edit data & words, but the forest resource information include attribute and spatial data, its character is territoriality, multi-dimension and dynamic so forest resource management system must processes not only figure and word information but also graphic information[2][3],information system based on database technology can not deal with those, and can not provide foundation for decision.
- Today, most of forest resource management information systems almost are singer computer software; it does not use network’s superiority, such as data share and transfer data, so a lot of human resource, things and money are wasted due to rebuilding information system.
- Forest information system is only used by forest unit, so it can not meet the public with obtaining, concerning forest resource information and participating in forestry decision.
2. Forest Resource Management Information system based on WEB and GIS is Development Trend
As RS and GIS technologies are widely used, forest resource investigation method is improved highly, the scope of investigation is wider and wider, and the cycle is shorter and shorter, abundant of information has been obtained, where the information is memorized and how to be memorized is the problem of standing in the breach which all forestry workers have to face as information age is coming, managing forest resource data with new technology is already a crucial thing [5]. GIS has strong function of managing and analyzing spatial data, can picture vividly the space-time distribution of resource and find out the changing principle of resource, Moreover, it provides a simple and prompt way to browse the models and relations of resource information GIS being used in forest resource management realizes modern forest space-time adjusting, predicting, decision, inspecting and evaluating, which provide a scientific foundation for realizing forest resource sustainable development and classification management.
