| 摘 要： | 以全国分县为基本研究单元,基于2000和2010年人口普查资料,依据高龄化系数将中国不同区域划分为未高龄化、浅度高龄化、中度高龄化和深度高龄化4个类型区,并探讨其空间上的地域分异规律。并选取5个自然环境指标,利用偏最小二乘法（PLS）,对高龄化水平区域差异的环境成因进行定量分析。结果表明：① 全国县域高龄化水平呈现“西疏东密”分布格局;高龄化系数三级阶梯状分布明显,平原、丘陵、盆地普遍高于山地及高原地区;由“凹”字型向“东西隆升、北端塌缩”格局演变。② 高龄人口空间集聚不断增强,区域间差异逐渐增大。③ 水文指数、气候指数是影响全国县域高龄人口集聚的主要因素;地形起伏度、空气质量指数对高龄人口分布影响不显著,对不同类型区影响差异显著;随着时间的推移,植被指数对高龄人口空间分布的影响趋强;社会经济因素对高龄人口分布具有扰动作用。 |

| Abstract: | The spatial distribution of the elderly population is a reflection of the man-land relation in a specific historical context. However, the spatial pattern and driving factors of the elderly population in China were not clear yet. Therefore, this paper using the fifth and sixth population census data in 2000 and 2010 analyzed the elderly's aging coefficient in China and divided the 2 328 counties into four types, consisting of not mature, shallow aging, moderate aging and deep aging then discuss the spatial regional differentiation. Secondly, choose 5 natural factors indexes and use Partial Least Squares (PLS) method to quantitatively analyze the influencing factors of elderly's aging coefficient in the whole country and four regions. The results show: 1) The elderly's aging coefficient present the “The western China is sparse and the eastern China is dense” distribution pattern. The aging coefficient showed three-step terrain from the west to the east, the elderly's aging coefficient of plain, hilly area and basin are generally higher than the mountain and plateau area. The evolution of aging coefficient from “concave” shape to “East West uplift-north end collapse” pattern. 2).The spatial agglomeration of the elderly population is increasing constantly, and the regional differences are increasing gradually. 3) The hydrological index and climate index are the main factors affecting the agglomeration of the aged population in China, RDLS and AQI have no significant influence on the distribution of the elderly population, and the impact on the different types of areas is significant. Over time, vegetation index has a strong influence on the spatial distribution of the elderly population, and social and economic factors have a disturbing effect on the distribution of the elderly population. |
