Study On The Planning And Design System Of Land Consolidation Based On GIS

Since the 1970s, the population of human beings has been growing rapidly. At the same time, the urbanization and industrialization has expanded with it, so as to cause many problems, such as land use, the decrease of land and the clash between man and land. The implementation of sustainable development policy deals with the problems of population, resources, environment, and land. Land, especially farmland as scare resources, is important to the implementation of sustainable development policy. Forever, land consolidation plays an important role in the adjustment of the relationship between man and land, the means of the optimization of land resources and the achievement of the balance of land use. And it also shows great potential.Geography information system (GIS) is an important part of information technology. This system can process geographical space data in the way such as collecting information, storing, accounting, and analysis etc, under the assistance of computer system. Since the 1960s, GIS technology has developed dramatically, and is used in many different fields. Currently, it is used wildly in resource management, traffic control, environment protection, and natural disaster monitor etc. And the technology is focused on 3S, 3 dimension GIS, virtual reality, Grid GIS client-oriented GIS.By using the theories, technology and methods of GIS, combing with the characteristics and standards of land consolidation, the planning and design system of land consolidation based on GIS is established. Therefore, the land consolidation planning and some data collection such as compiling, organization, managing has a guarantee to high quality planning.Based on research both home and aboard, this thesis discusses the feasibility and significance of establishing the planning and design system of land consolidation, and propose the contents and the characteristics of the research and some new ideas of the author. After analyzing the principles of design, the author explains the structure, function and data base of the system and also analyses the platform MapInfo, the programming language MapBasic, and the environment of software and hardware. This system consists of basic function modules (login module, main module, data management module, information chose and inquiry module) and specialized function modules (plan designing module, project designing module, maps drawing module, earthwork calculating module and budget computing module). In the fourth chapter, the detailed description of the modules is given. In the sixth chapter, the specific example-land consolidation of Xiaoling county, Shaping Chongyang village,Chongyang town, Hubei province is analyzed. It conclude that the system not only easily operated but also efficient.
