[目的] 对江西省人口-经济格局变化进行分析
为新常态下区域层面的人口与资源环境协调发展提供量化依据。[方法] 基于江西省数字高程数据
运用ArcGIS技术
采用窗口分析法
提取江西省地形起伏度
系统分析地形起伏度的空间分布规律及其与人口、经济的相关性。[结果](1) 江西省的地形度以低值为主
88%的县域地形起伏度小于0.5
东、南、西部3面高
中部和北部低
在空间分布上呈现U形特征;(2) 江西省人口、经济集中度总体上北高南低
人口向地势较为平坦的北部区域集聚明显
经济整体向北部鄱阳湖生态经济区集聚;(3) 江西省2000-2010年10 a间
受地形起伏度影响
起伏度小于0.25的区域人口集中度的比重由2000年的59.23%增加到60.47%
相应地经济集中度所占比重由2000年的72.80%增加到75.49%。[结论] 江西省地形起伏度与人口、经济存在较强的负相关性
区域人口、经济表现出随地形起伏度下降而增加的趋势。
[Objective] The relief degree of land surface(RDLS) is one of the key factors that influence the population distribution and economic development. Investigation about the pattern changes of population distribution and economic development is of importance to give a quantified prospective harmonization of population
resources utilization and environment conservation. [Methods] The RDLS of Jiangxi Province was extracted based on a 90 m resolution digital elevation model(DEM) using focal function under ArcGIS software
and then the features of RDLS
and its correlation with population and GDP were analyzed. [Results] (1) The RDLS in Jiangxi Province was prevailed by low value
e. g. 88% counties less than 0.5. Spatially
the outliers of Jiangxi Province had higher RDLS with the exceptions of the central and north parts
showing a "U" shape of pattern. (2) Overall
the concentration degrees of population and GDP were larger in the north and smaller in the south of this province. Spatially
the population in this province clearly assembled in the north with flat relief pattern. The province's GDP continuously concentrated in the Poyang Lake Ecologic Economic Zone. (3) During 2000 to 2010
population concentration degree increased from 59.23% to 60.47%
accordingly economic degree increased from 72.80% to 75.49% in the regions with the RDLS less than 0.25. [Conclusion] There was a strong negative correlation between the RDLS and the distribution of population and economy. As the RDLS increased
the concentration degrees of population and economy declined
