Analysis On The Economic Potentiality Of Cultivated Land Reserve Resources In YuJiang

Under the background of industrialization and urbanization, population growth and the rapid development of social economy, make the demand for land resources in various regions become more and more obvious. Under the basic state policy of people oriented,our first priority is food security, which is an important way to solve this problem in the current society, the rational use of cultivated land reserve resources. For the evaluation of the economic potential of arable land reserve resources, can for cultivated land accounted for compensation balance, land consolidation, land planning and development and utilization of provide the basis, is advantageous to the resources of the rational use of, is conducive to the layout of the overall development of the region and on regional food security safeguard and the resources the sustainable and stable development is important.In Yujiang County as an example, based on the theory of land supply, from the perspective of the physical supply of land to the land of natural appropriate tillage is evaluated, to determine the scope of Yujiang County of arable land reserve resources; at the same time, the land economic supply angle of reserve resources of cultivated land economic potential evaluation and analysis referring the research results of domestic and foreign experts and scholars on the land evaluation to determine its economic potential value. The natural land suitability assessment mainly in accordance with the requirements of related regulations, the "limiting factor" method to determine land suitability, identified a total of 1210.78 hectares, involving 830 maps can be reclaimed reserve resources; on this basis, from the perspective of sustainable development theory, location theory, resource endowment theory construction, evaluation factors with Yujiang County cultivated land reserve resources and economic potential, and the use of land development project in Yujiang County for years as the sample data, the correlation between the factor screening and verification, economic potential, finally established the natural potential, water conditions, traffic conditions, in the town of famous distance, the rate of land reclamation rate, input and output the economic potential of the revised index as a total of 6 factor ratio.By analytic hierarchy process AHP analysis method to determine the weight of each index,GIS technology will use the basic data vectorization, and on the assessment unit, spatial analysis, obtain evaluation index value data, by weighting for law and economic potential of 830 block reserve resources of cultivated land value is obtained, and the potential level is divided into three levels, including a potential area 309.15 hectares, secondary potential area 449.35 hectares, three potential areas 452.28 hectares, and economic feasibility of Yujiang County of arable land reserve resources development were discussed, and put forward some suggestions according to the present situation of Yujiang County.
