The Research On Evaluation Of The County Reserve Land Resource And The Strategy Of Exploitation Based On GIS

An area's economical development creates the demand pressure inevitably to the land resource,therefore the reserve land resource's development use appears especially important. The reserve land resource appraisal for the territorial management, the land development, uses, plan and land utilization system's aspects and so on formulation provides the scientific basis. It is advantageous in realizes the reserve land resource reasonable use, the promotion land resource sustainable development, for other local research reserve land resource's development, the use and the protection provide certain theory reference.In this paper, and foreign reserve land resources evaluation of the progress, defined the research methods and ideas. Read a lot in the literature on the basis of the study clearly the true meaning that the principle of scarcity of land, rent theory, people coordination theory, dynamic equilibrium theory, systems engineering theory, and so constitute a reserve of land resources evaluation of the theoretical basis. In research methods, learn from their predecessors many of the results of research on reserve land resources evaluation index screening principle that follow the principle of comprehensive, guiding principles, the principle of stability, the difference of principle, the principle of regional and operational principles.In the expert analysis of common research method (DELPHI), the minimum standard deviation, correlation analysis and principal component analysis, and other targets identified on the basis of the ultimate method of determining the use of expert research method (DELPHI) indicators for the integrated system and the internal factors External factors≥10℃effective temperature, altitude, irrigation conditions, geographic conditions, the effective thickness of soil, soil texture, organic matter content of these seven factors. And in the light of experience of previous research results on the basis of indicators threshold, the delineation of indicators to evaluate and determine grade-level indicators points. The right to re-establish indicators of the importance of considering the level of comprehensive analysis and ranking of the advantages and disadvantages, this level of analysis used to determine index weight.District adopted the method of superposition evaluation unit in the evaluation process is an important basic work. The first step, use mapgis, MapInfo, AutoCAD, and other cartographic mapping software evaluation of classification maps and graphics give the corresponding attribute; second step, Mapgis software in the use of spatial analysis functions in the area superposition functional evaluation to 49,187 units Each evaluation unit contains the evaluation of the property value, the third step, Mapgis the management of the properties in the output attribute data, compiled by VF in the program, the evaluation unit to calculate the total score; fourth Step, Mapgis attributes management will evaluate the unit and evaluation unit carried out scores of links to the fifth step, through Mapgis statistical analysis of the space distribution of the total units, with greater frequency in the points classification as the interval , The total score will be divided into four, as reserve land resources development potential of a potential area, two potential areas, three potential areas and four potential areas; fifth step, through the graphics editor will be graded display Out and analyze the potential level of composition and spatial distribution.In this paper, taking into account the development of reserve land resources must be integrated strategy for the development of various factors. Land development potential reflects only the conditions of their own land, the land development process also need to consider the economic, ecological, social benefits in three areas, so by comparing the various options, the highest-elected eco-efficiency, high economic efficiency and social benefits of the highest - Three options. Make use of the methods of multi-objective planning. Finally, I decide to make the first goal is maximum ecological benefits of the program. In accordance with this program and set the development of reserve land resources in the overall goal. In order to better achieve the development goals, for worship County reserve land resources and the distribution of potential levels will be divided into a potential key development zones, divided into two divisions optimize the potential of development zones, divided into three potential zoning restrictions on development, Divided into four potential prohibition of the development and focus on protected areas and to develop the district development objectives and strategic focus.After verification, the paper set the development objectives and strategic focus with the local "11 ? 5" basically consistent with the plan, so the door can be developed for the Ministry of Land and Resources under a general land use planning reference. For the development process of the main problems, constraints, such as developing security measures for the smooth implementation of the strategy of developing protect.
