Stem Analysis Information Processing System Based On The J2EE Technology Of Browser/Server Structure

Stem analysis is to determine the individual tree diameter at breast height,tree height and volume growth and other factors the most accurate method.Individual tree stem analysis results can also stand the past,present,and future growth,also estimate and speculate to understand the stand of individual groups and the growth of trees changes.Therefore,it is widely applied in calculating the growth,in the process of the preparation of growth forms and other items of index table in forestry production and research work..It become the basic method in studying the process of tree growth.Take Forestry Bureau in Jilin Province Wangqing's stem analysis data as an example.I built the information of querying and administrating system of stem analysis system based on the technology of J2EE of Browser/Server structure.The sytem is the realization of the environment on the Internet of information on stem analysis information's Processing,query,statistics and dynamic updates,and a good resolve to meet the user demand for information-sharing.This paper introduces the stem analysis in forestry research.Computer is in the application of stem analysis to investigate the status and developments.On the design and development of stem analysis information Processing system of forestry is important for workers and researchers of forestry.This system achieve better standardization of the system development.I have to collate information on stem analysis data.Stem analysis module is divided into the following ten categories:Stands of forest condition module,Tree characteristics module,Crown projection module,Adjacent to tree module,Growth over the past five years module,Analysis of records of the trunk module,Volume records module,Tree growth process module,Growth curve module,Tree profile chart module.I design and development of each module and completed the various functions required by users:Stands of forest condition table,Tree characteristics table,Crown projection table,Adjacent to tree table,Growth over the past five years table,Analysis of records of the trunk table,Volume records table,Tree growth process table,Growth curve table,Simulation curve equation,Curve,Curve bar,Tree profile chart and so on.System would offer to forestry researchers to provide accurate,timely,comprehensive information and processing results and raise the stem analysis data processing efficiency.This system based on the technology of J2EE of Browser/Server structure is based on Java platform, and uses lightweight framework combination:struts+Spring+Hibernate,which also used in the research and development of Web-based Stem Analasys information Processing system.Meanwhile,the system also employs Ajax to construct more dynamic and sensitive web applications.The combination between three frameworks and Ajax lets J2EE development has better scalability and maintainability; can fully play their respective advantages,and realizes the LCN of Web-MIS development and good user experience.Therefore,this system has very good prospect.
