The Study Of Idle Land Utilization Based On Multivariate Statistical Analysis And GIS Spatial Analysis

The utilization of idle land based on land suitability and land capability plays an important role in promoting the construction of resource-saving society and the land using efficiency, Using the principal component analysis, cluster analysis methods, and spatial analysis methods such as Spatial interpolation, Space partition, to understand the impact of the pilot area of idle land, land suitability characteristics and land potential, and give comments on how to improve the efficiency of land use proposals idle.The formation of idle land using has regional differences, and the factor which influence the idle land is difference, that can be mainly summarized as follows:social factors, economic factors, and government factors. In different regions, the proportion among the three is different, The management and utilization should be adapted to local conditions. The pilot area of idle land suitability divided into 5 classes:the first class belong to the appropriateness of commercial land, Second class is more appropriate for commercial and residential land, Third class belong to the appropriateness of residential land, Four other places are more suitable for residential and industrial land,The five class belonging to the suitability of industrial land.Different land uses such as industrial, commercial, residential, etc., can lead to differences in the potential of idle land, in the same time, the phenomenon of land store have revealed the internal factors that have significant economic benefits of land prone to idle, especially that in the areas with high yield is easy to become the objects which developer want to store. According to different income levels, Potential of the pilot area of idle land is divided into four grades. And take appropriate use of measures according to different levels.Establish a good warning system is imperative, through the evaluating the potential of idle land, establish the warning system of land classification, and give management and supervision from different idle land. The pilot area was divided into four early warning:serious warning area, a high alert warning area, moderate areas, low warning zone.According the pilot area of idle land distribution to give the prevention and treatment recommendations.
