【摘要】：人口经济的时空耦合态势是中国区域社会经济发展空间均衡过程的重要体现,可有效地指导中国经济布局、民政建设、交通发展和环境管理等相关政策和措施的制定和实施。在地理信息系统(GIS)的支持下,采用人口分布结构指数、人口密度基尼系数、人口经济重心迁移、空间自相关分析等方法,对1935年—2010年6期县级行政单元人口普查统计数据进行空间插值,实现人口密度分界线的空间刻画及其变化趋势分析,结合1952年—2010年省级行政单元人口、经济统计数据,从人口与经济重心空间耦合及其空间一致性两个角度来揭示社会经济与人口分布的时空差异,剖析人口分布与社会经济的联系。得出以下结论:(1)由于社会历史、自然环境和经济条件的影响,中国人口空间分布的时空演变特征不尽相同,东西部差异较大,且不均衡态势日益明显。(2)胡焕庸线至今仍能很好的概括中国人口东南地狭人稠、西北地广人稀的空间分布格局,但是甘肃、宁夏、内蒙古地区的人口分布已经在局部范围内突破了胡焕庸线的限制,中国人口分布在一定程度上呈现向西部转移的趋势。(3)中国人口分布与经济发展空间一致性的地域分异特征十分明显,但省际一致性在不断缩小,人口集聚具有较强的经济导向性。(4)全国和东部、中部、西部和东北部四大区域在1952年—2010年的人口经济一致性程度及其变化趋势各异:全国人口经济空间一致性程度相对较低,东北地区人口经济一致性程度较高且还在改善,东部与中部保持稳定,西部较差且呈减弱趋势特征。
[Abstract]:Time and space coupling situation of population and economy is an important manifestation of regional social and economic development China spatial equilibrium process, can effectively guide the layout of economic Chinese civil construction, the formulation and implementation of the traffic development and environmental management and other related policies and measures. In the geographic information system (GIS) under the support of the population distribution structure index, population density the Gini coefficient, population and economy gravity transfer, spatial autocorrelation analysis, spatial interpolation of 1935 - 2010 6 county-level census statistics, spatial analysis and trend of population density characterization of demarcation line, combined with the 1952 2010 provincial administrative unit of population, economic statistics, to reveal the social economy and population distribution the spatial and temporal differences from two aspects of consistency of population and economic center spatial coupling and spatial analysis, population distribution and social economy Contact. Draw the following conclusions: (1) because of the social history, natural environment and economic conditions, the temporal and spatial distribution of Chinese population spatial evolution characteristics of different things are quite different, and the unbalanced trend is increasingly evident. (2) the Hu Huanyong line still can be a very good general population China narrow land southeast thick, spatial distribution pattern, northwest of Ningxia, but with much land and few people in Gansu, the population distribution in Inner Mongolia area has exceeded the limit of Hu Huanyong line in the local area, Chinese population distribution trend shift to the west to a certain extent. (3) the consistency of population distribution and economic development Chinese spatial regional differentiation characteristics is very obvious however, the provincial consistency in the shrinking population with strong economic orientation. (4) the central and Eastern, Western and northeastern regions on the four degree of consistency in 1952 to 2010 the population economy And its trend of change is different. The degree of consistency of population economic space is relatively low in the whole country, and the degree of population economic coherence is relatively high in Northeast China, and it is still improving.
