Abstract:
The purpose of this paper is to explore the spatial agglomeration characteristics and influencing factors of cultivated land reserve resources around the class,providing theoretical basis for the development and utilization of cultivated land reserve resources,by statistical methods,including Gini coefficient and the trend analysis method. The result demonstrated that(1)the agglomeration of cultivated land reserve resource varies widely in different classes,reclaimable coastal beach>reclaimable wetland>reclaimable sand-strewn area and reclaimable mining field>reclaimable inland beach and reclaimable saline and alkaline land>reclaimable bare land>other reclaimable grass.(2)Reclaimable coastal beach mainly gathered in the mid-latitude zones along the east coasts,reclaimable wetland and mining field are located particularly in east-northeast areas and reclaimable sand-strewn area is mainly in the northwest region.(3)Natural factors lay the basic pattern of spatial distribution,demographic factors on the combined effect play role in shaping and economic factors are involved as a cofactor,but its position of great influence on cultivated land reserve resources’ sustainable utilization is improving. It is concluded that spatial distribution of cultivated land reserve resources is revealed and quantized by Gini coefficient and the trend analysis method,which interpret the agglomerative characteristics and provide a scientific basis for the exploitation measures.
