赣南苏区可利用土地资源空间分布特征分析

The Analysis to the Space Distribution Features of Available Land Resources in Jiangxi South Soviet Area

可利用土地资源是评价一个地区剩余或潜在的土地对未来人口集聚、工业化和城镇化发展的承载能力,其数量和空间分布对该地区的经济发展后劲、发展潜力及环境保护具有重要的影响。根据2011年Landsat TM遥感影像人机交互判读解译江西省土地利用数据并结合江西省DEM数据,分析得出江西省赣南苏区可利用土地资源空间分布特征,结果表明:(1)赣南苏区可利用土地资源总量5 845.02 km2,占该区土地总面积的14.9%;(2)各县(市、区)域之间可利用土地资源数量和空间分布不均衡;(3)经济发展较好并且人口密集地区,土地的开发利用程度高,可利用土地资源少,反之则较多。

The available land resources are used to evaluate the surplus or potential land in a region which shows the bearing capacity of the population concentration, industrialization and urbanization development in the future. The area of available land resources and spatial distribution have impor- tant implications to the economic, potential development and environmental protection in a region. According： to the 2011 TM image by Landsat to interpret the data of land use which combined with the DEM data of jiangxi province to draws a conclusion of the the space distribution features of avail- able land resources in jiangxi. The following conlusion showed ： （ 1 ） The total available land resources is 5 845.02 km^2, accounting for the total land area 14.9% in jiangxi province ; （2） The quantity of available land resources and the space distribution are imbalance between the regions;（3 ）The land exploitation degree is high where is economic development and densely populated, so the available land resources is less but more conversely.
