The Design And Development Of The Conversion Cultivated Land Into Forests Management Information System

The conversion cultivated land into forests, is one of the key of the our country ecosystemenvironmental protection and the constructions, is the important measure that can improve theecosystem environment, guarantee and promote the region to keep on the development.It also isvalid form that supports the poverty to take it by storm and improve the ecosystem environmentknot to put together, and benefit the crowd who live in the poor region takes off the poverty toamass a fortune. Being one of the six greatest forestry projects, it's constuct result have the directrelation with carrying out the development of the forestry .Having maked experiements since 1999, the project of the conversion cultivated land intoforests has already obtained the obvious result. But with the expanding continuously of theengineering scope and the strengthing continuously of project, the traditional management modeand meanses of the project can't adapt the more and more huge and complicated managementdemand of a system project. The county class project of the conversion cultivated land intoforests especially is the key. The means fall behind, the level is lowly, and the existent problemis also more and more obvious, such as: The means of programming design fall behind, and theproject mission is hard to carry out. It result in the programming design been out of accordancewith construction homework; The information is hard feedback and renewal in time, conduct theactivity to check before acceptance the result and can't enter the information managementprocess in time; The information between the all levels project management section can't deliverin time, and is hard to carry out information share etc.. The existence of these problems, lead themanagement and supervisions of the conversion cultivated land into forests to be in difficulty,affected the programming and managing, supervising and controling, making policy, evaluatingand analyzing of the project.Therefore, making use of the modern calculator and the information technique meanses,resolving the management problem and raising the level of the county class project of theconversion cultivated land into forests is urgent.On this demand foundation, the national forestry bureau, Chinese forestry science resourcesinformation graduate school, Peking zondy science and technology limited company decide todevelop the national county class conversion cultivated land into forests managementinformation system.This file is close to the topic of the management information system, to the analysis andresearch that the design and developments of the system, as follows:(1)The study is carried on for the problem in present condition, particularly the county classmanagement present condition.These problems synthesize to reflect the necessity.of the systemconstruction according to the geographic information system. At the same time, we also discussthe benefits with the CFMIS development.(2)According to the characteristics of the geographic information engineering, we studiedthe software engineering mode of the construction, and put forward the detailed developmentproject.According to the actual county class project management need within work, we designed thesystem structure, carried on the thorough analysis to the module structure, the dataprocess...etc..These are all the foundation of the project construction, and they can guidenormally the project construction to carry on. (3)Carried on the research to the system structure of the geographic information systemfoundation platforms, include the data management, the space entity and its data organizationetc.. (4)Through the thorough research to the conversion cultivated land into forestsmanagement information system characteristics, the decisive technique of system researches tomanufacture the process is carried on. For the actual application, the key techniques such as thedesign of the data dictionary, the editting of data record, the data browse, the data formatconversion and the data manifestation are carried on researching. This file acquires the following result: (1)Designed and developped the national county class conversion cultivated land intoforests management information system. The county class project of the conversion cultivatedland into forests management is in most foundation. It still mainly adopt the way with writtingrecord, and all data building the volume in traditional management mode. With the project of theconversion cultivated land into forests, tradition management mode and means can't satisfyusually need of transact the business, affected the engineering and management, supervision andcontrol, evaluation and analysis of the project. This system not only broke the traditionalmanagement mode, but also had characteristics of combining the business process, strict designaccording to the business process, obeying the standard, searching vividly the function, printingthe sketch and the form and list methods strictly vivid, the good system safe mechanism etc.. Atthe same time, this system filled up the blank of the automation management software in theproject of the conversion cultivated land into forests. (2)The research and realizations of the system key technical. The data dictionary is thefoundation module of the system. The success that it design or not affect the success or failure ofthe whole system directly. The main function of the data dictionary is to translate and explain thedata. This is an important function that the customer concern mostly. The data editting is the paththat the customer import the data. Its design relate directly to the satisfaction of the customer andthe accuracy of the databases. When editing data, the system adopt the function of the logiccheck and compute automatically. The logic check can guarantee the importation of the datacorrectly. Thus it can ensure the accuracy of the data in whole database. Automatic calculation,can help customer reduce many workloads, and avoid the importation of the mistake data. Thedata format conversion, is the function that the customer concern mostly. So the conversion of...
