The Study Of The Silviculture Information Management System Of Guangzhou

This article synthesis the software engineering methodology, computer technology and GIS technology, in view of current actual situation of the management of Silviculture technical of Guangzhou and our country present stage and recent years forestry informationization trend of development and the demand, through to forest, information, management science, economic, systems science correlation domain thorough research,By use of 3S technologies and the integration technology, data bank technology, network and dynamic homepage technology, management information system establish one based on current mainstream TCP/IPT and the Internet networking, realizes to builds the forestry work regulation the cross platform management. This system structure interior local area network uses the C/S pattern, the foreign information inquiry counts and issued uses the B/S pattern the architecture, this may both use the forestry bureau interior network effectively, provides the realization complex function for the user the interactive function, the realization Silviculture technical information material and resources sharing, and may guarantee the modern forest management department opens the information environment to the demand, When the enhancement and outside relation needs through Internet development network on service.the kind of patterns displays the superiority.This Subject is to build forest management of technology and carry on research of the city of Guangzhou, mainly solve the problem of information-based management of the forest technology, including structure one reasonable effective long-range administrative system and the kind of technology realize the management information system.1)This system is designed by the object, operational activity, user's needs, monitor and evaluation criterion for the management information system.according to the building of the forest technologically, afforest, close hillsides to facilitate afforestation, the transform of the low quality less effective forest, the young growth foster room cut down, mend, plant, apply fertilizer all technological all characteristic of activity plant into the systems, combined with each management of all kinds of activities, is beneficial to building the harmony that the forest worked.2) This system can be followed and built by the characteristic of different activities while the working of forest, design, develop, collect, the built of forest project recommendation manage, the built of feasibility research of forest manage, the Silviculture plan, the design, the construct control, the inspection approval, the project verification, the statistical report form and the condition inquiry, the special chart inquiry and the output in a body network Silviculture technical management information system amony, and the resources dynamic renewal and so on the various links information production, the maintenance, the use and the renewal mechanism integrates, is a more comprehensive forestry control principle system.3)In the 3S technology and the computer technology, forms the forest resources foundation database, in the spatial database foundation in the forest resources management information system and in the ORACLE9i database platform, to establish the Silviculture activity type special-purpose database. Through to Silviculture technical management information systemseven big functions:data integrated management, multiple source data, method, knowledge library integration andinquiry, data generalized analysis,,specialized charting and Cheng Tu, remote sensing image analysis, vector data analysis processing and three dimensional visible resultdemonstration and inquiry, causes it to realize each management process information.4)This system is the application system which is completed by the development of the forestry database of Guangzhou, its data besides.comes the self-management afforestation technicalmanagement special-purpose database, still needs (for example forest resources management informationsystem) center gains the data from other systems;This system make use of the register hand, network transmission and remote sense carries out the renewal on the data for ensuring that the information accuracy.5)The system of that data base administration adopt the operation environment allocation, consumer managing, distributing within the power of and so on to the data base to be in progress interpose. Run an environment and run a parameter by optimizing a data base,assign consumer extent of authority rationally and make use of mechanism, by the view of the mechanism, the consumer write down the two steps to the administration that the consumer authorizes to carry out administration on its data base completeness coming managing, using the fire prevention wall and so on, to guarantee the data's compatibility and security.6)How to solve this problem that many data based on share, keep each data bases fixing and the renewal extent of the authority and the secret working reaching, and in the operation, the project still have many job to compose.
