摘要
人口分布是指人口在一定时间内的空间存在形式、分布状况,包括各类地区总人口的分布,以及某些特定人口的分布等。文章运用空间自相关分析理论,结合GIS技术,探讨了1978—2010年江西省县域人口空间分布的变化规律及特征。结果表明:在研究时间内全省人口总数持续增长,但增长速度减慢。极差由22.52扩大至38.61,标准差由184.12扩大至38.61,变异系数和锡尔系数的变化趋势一致,从1978年的0.82和0.19分别增长至2010年的1.17和0.28。这说明江西省人口密度在研究的时期内离散程度、相对差距、绝对差异都增大。全省人口分布呈现北高南低的特征,浙赣线以北地区高人口密度区形成由点状分布逐渐演化成片状分布的结构特征且空间差异度程度在减小,浙赣线以南地区形成以赣州市为高人口密度中心整体人口密度较低的现状。1978、1990、2000、2010年位于H-H和L-L象限的县域个数分别占80.21%、78.02%、69.23%、68.13%,从而表明30年以来江西省人口空间分布的聚集分布有下降的趋势。
Population distribution refers to the form of ＇space existing and the distributing condition in a certain time, which includes different area distribution of the total population and some specific population distribution. By means of spatial autocorrelation analysis theory and combined with GIS technology, this article discusses the changing rules and characters of the population＇ s spatial distribution in the counties of Jiangxi province between 1978 and 2010. The results show： the total of population keeps increasing in the research period , yet the increasing speed slows up; the dispersion degree, the relative gap and the absolute difference of the population density enlarge ; the population distribution of the whole province has the characteristics of higher in the north and lower in the south. Besides, the number of the counties located in H-H and L-L quadrant in 1978, 1990, 2000 and 2010 accounts for 80.21%, 78.02%, 69.23% and 68.13% respectively, which shows the gathering of the population＇ s spatial distribution has a tendency to decline since the last 30 years in Jiangxi province.
