GIS Construction And Application Research Of Forest Disease And Pest Management Of Heilongjiang Land Reclamation

The paper mainly elaborates"Forest Disease and Pest Management Information System Construction and Application of Heilongjiang Land Reclamation"development process and realization method,has completed 2 subsystem's design and construction and development work.2 subsystems:forest disease and pest essential data processing subsystem and Forest plant disease network issue subsystem.It is very perfect to use advanced GIS technology, module technology,database technology and network technology together,and using the Suihua sub-bureau of bureau of Heilongjiang Province Land Reclamation have carried on the test to system.The system has following character:1.The system uses VB6.0+ArcSDE+ArcObjects+SQL_Server development way,the developing platform is windows2000 Server,the simply fast merit with VB6.0 development system.Moreover,transfers ArcObjects framework storehouse conveniently,the system needs each kind of GIS operation mainly completion by ArcObjects framework storehouse.Through ArcSDE spatial data engine,inducts spatial geography data and disease and pest attribute data to SQL_Server database,satisfies disease and pest data reserves to be big,data frequently visit as well as data expands need conveniently,has provided technical support for the system.2.The system issues platform uses ArcIMS as geography information's network,uses Weblogic 8.1 as Web server,ArcSDE was used as spatial data engine,using ArcIMS provides Java Connector,carries on WebGIS development,Uses Java as Web development language, merges complex alternately systematic JavaBean+JSP+Servlet's MVC pattern and B/S design structure into one organic whole,constitutes perfect network issue system.Issues 22 kinds of disease and pest information of Heilongjiang Province Land Reclamation frequently and seriously on-line,causes basic unit forest protection personnel through browsing forest disease and pest picture,distinguishes forest disease and pest's type,discovers forest disease and pest's prevention method promptly.3.In the essential data processing subsystem,has used the C/S structural design,has completed the data organization and processing,the contact surface expression and the interactive function,Carry on plant disease functions accurately and so on.information input, data fast inquiry and statistics,all previous years reexamination and year investigation,analysis, inquire the reclamation area to have 22 kinds of plant disease information fast,plant disease investigates number seriously,the distributed situation,the harm degree,to have the area and so on,prevents and controls for the reclamation area forest plant disease,provides the policymaking basis. 4.The system used Asp the module to complete the common 22 kinds of plant disease picture to upload to the database function realizes.It realizes the process to divide into the client side and the server two parts.Client side execution picture browsing and designation function;The server end completes the picture to save by the JPG form to the system database, for plant disease information network issued that has provided the material.5.System design network report form function.The network report form aims at the complex form the report data and Web the report form development,henceforth,got rid of the traditional report form the malpractice which supports with difficulty generally to the multidata sets,raises the manufacture report form efficiency.6.In order to assure the data security,the system designs three levels of users:Super user, high-quality and general user.The super user is bureau,the high-quality user is sub- bureau,the general user is farm.In view of the different user is different,the super user has the biggest jurisdiction,may increase user,may change user's information,may delete user.High-quality increases and changes respective farm user's information.The general user can only revise own information and password,cannot revise other user's information.Like this,protects bureau, sub-bureau and farm's knowledge achievement and intellectual property rights effectively, provides the possibility for the data security.7.Looking from system's design performance,the system uses the general high-level programming languageunion geographic information system module,is the forestry carries on the geographic information system development one quite good integrated re-development way. Using the general programming language to be possible quite convenient to carry on the system function and the contact surface development.But uses the geographic information system module to be able to avoid the complex geographic information system first floor function development work,Both reduced the development cycle,reduced the development work load,has guaranteed system's stability and the reliability,and may realize system's seamless integration.The system uses the confirmation through Heilongjiang Province Land Reclamation bureau Suihua sub-bureau forest disease and pest management work.this system has very good application prospect and use value.
