Study And Application On Evaluation Information System Of Parcelland Price Based On Land Grading And Evaluation

The evaluation information system of parcelland price accomplishes the processes of land pnce valuation and analysis with computer system. At present, most of parcelland price evaluation information systems still lag behind in technology. The systems didn't use GIS, or they integrated with GIS loosely. Especially, they couldn't make fully effective use of the results of new round national land and resources investigation. Along with the development of GIS technology and the publicity of government information data, it is possible to develop the evaluation information system based on land grading and evaluation by GIS technology. In this paper, the author accomplishes the development and application of the system by using development language VB and geographic information systems software Maplnfo.On the basis of explaining the relevant connotation of parcelland price evaluation, the author analyses the background and significance of system construction, and discusses the way of evaluation information system of parcelland price design and development strictly according to regulations for valuation on urban land. At last, the author accomplishes the system's software development, and takes Jiangsu Wuxi chaoyang (group) limited company reform of enterprise evaluation as an example, and achieves anticipate purpose.In Section A, firstly the author expounds the meanings of evaluation of parcelland price and benchmark land price. Secondly, the author expatiates the background and significance of system construction. Finally, the author brings forward the thought of the evaluation information system of parcelland price, which is based on land grading and evaluation.In Section B, the author discourses on the systems analysis, which consists of user definition, requirements analysis, feasibility analysis, data analysis, etc.In Section C, the author discourses on the process of the construction of the information system, which consists of general target, function design, data flow, software and hardware design, evaluation model, data dictionary, main functions realization, interface design, flexible system design, system integration, etc.In Section D, the author introduces the tests and the applications of the system, taking Jiangsu Wuxi chaoyang (group) limited company reform of enterprise evaluation as an example.In Section E, the author draws his conclusion and puts forward several pieces of suggestion on further study of evaluation information system.In the course of study, the author follows the principle of the relationship of theory to practice and expounds his own opinions. The study results are as follows:1. Strictly following national regulations, the author designed and accomplished the evaluation information system of parcelland price based on land grading and evaluation.2. Using the system, the author accomplished more than seventy parcelland price evaluation of Jiangsu Wuxi chaoyang (group) limited company, which offered a successful example by using the advanced technology for parcelland price evaluation.
