【摘要】：基于地理空间视角,根据第四、五、六次人口普查数据,运用统计分析、空间分析以及多元逐步回归,探究了东北地区1990~2010年人口变化的时空间特征及其影响因素,以期为东北地区推进新一轮振兴战略并实现人口、经济、社会、环境协调发展提供依据。研究结果表明:(1)研究时段内东北地区人口增长率低于全国平均水平且增速趋缓,尤其是进入新世纪以后,人口增长愈加乏力。(2)区域内部人口增长的主要动力不同。人口的迁移流动对人口空间格局重塑起到决定性作用,人口南移已是东北地区人口空间演变的主要趋势。(3)人口分布的"核心—外围"梯级格局表现出"极化"发展态势,人口空间分布的非均衡性加剧。(4)人口增减变化空间配置不均匀,人口减少单元明显多于人口增加单元。大部分地级市市区人口快速增加,而中心城市周边市县、资源型市县以及边境市县的人口则不断减少。(5)经济水平、行政级别、就业水平、医疗水平、产业结构均在不同程度上对1990~2010年东北地区的人口变化具有显著影响,而经济水平对人口变化的牵引作用最强。
[Abstract]:The geographical spatial perspective, based on the fourth, fifth and the six census data, by statistical analysis, spatial analysis and multivariate stepwise regression analysis, explores the characteristics and influence factors of space-time change of northeast population 1990~2010 years, in order to promote a new round of the Revitalization Strategy and realize population, economy, society for the Northeast region, provide the basis for the coordinated development of the environment. The results show that: (1) the study period in Northeast China population growth rate is lower than the national average and the growth rate has slowed down, especially after entering the new century, more sluggish population growth. (2) the main power within the region of population growth. The population migration to the decisive role in reshaping the spatial pattern of population, population. It is the main trend of population spatial change in Northeast China. (3) the population distribution of "core periphery" ladder pattern shows "polarization" trend, spatial distribution of population Non equilibrium aggravate the cloth. (4) the population changes in spatial allocation uneven population decreased significantly more than the increase of population unit unit. The rapid increase in urban population and most of the city center of the city, the surrounding cities and counties, cities and counties and the border counties resources population is decreasing. (5) the economic level, administrative level, the level of employment that level of medical and industrial structure are in varying degrees of population change in Northeast China 1990~2010 has significant effect, and the traction strongest economic level on population changes.
