The Research On Customization Platform Of Forestry Application System

The construction of forestry informationization is an important part of modern forestry construction. It is of paramount importance to promote the scientific development of forestry. To accelerate and promote forestry informationization is beneficial to build up forestry information system that cover the forestry department at all levels, and also has important significance to improve the level of forestry information service and to promote the scientification of forestry information service. Viewing the present situation and the existing problem of forestry informationization, We need to research and develop a fast, high efficient, convenient forestry application system customization platform to implement application system highly integrated in each forestry department. Which promote the forestry sustainable development is of important theoretical and practical significance.The research of this paper is an important part of a major project "Guangzhou Digital forestry and trees of wood protection system construction projects"(GZIT2010-ZB0533) which is charged by my mentor as the total technical director. This paper takes the system science, information science, management science, and forestry science and othe theory as an instruction, conduct complehesive study of forestry application system customization platform. During the course of the study, the research progress at home and abroad on forestry informationization and application system customization platform, and so on, are reviewed. I studied the three following aspects which are the supporting technology of customization platform, the whole design of forestry application system customization platform, the design of WebGIS developing framework of forestry application system customization. Based on this, I applied it on a case system. This paper focused on the following points in details:(1) Combined with the characteristics of forestry information system, this paper studied the related theory and technology of forestry application system customization platform. And using the WCF service technology, Silverlight technology, components technology constructed the technology architecture of forestry application system customization platform.(2) Using the theory of computer software engineering, this paper analyzed the forestry application system customization platform. Based on this, the paper comducted the function demands, design principles, and the overall framework of this platform.(3) Taking advantage of the.NET platform technology, Window Comunication Fundation (WCF) technology and Silverlight technology, the paper developed the parsing system of Web framework, system structure, function module and system service of forestry application customization platform, and constructed the prototype of platform at last.(4) Using ArcGIS for Silverlight technology and Silverlight technology, this paper constructed the WebGIS developing framework of forestry application customization platform, and designed the basic function, query function, and spatial analysis function, and finally, realized map zoomin, zoomout, pan, lengh and area measuring and the map dynamic overlap with tiled map services, dynamic map services, and image map services, and map layer of content, and thematic map of content.(5)Taking Guangzhou digital forestry platform as an example and "business applying in Non-Commercial forestry" Approvals of Non-Commercial forestry system as a business function, the research realized the customizing of data table architecture, form, workflow, portal and previlege setting and rule extension, and finally realized the business applying approval within Non-Commercial forestry.Customizing application system is a new arisen manufacturing and producing mode based on information system, and network technology, and is gradually becoming the mainstream of the IT industry production mode. Forestry application system customization platform researched and optimized on the existed customization platform technology, and merged the charactoristics of forestry application system to develop personalized forestry application system production platform. With the rapid development of science and technology, new theory, new method, new technology will apply in forestry application system customization platform further. Forestry information management and services will also step into a new level.
