【摘要】：以长株潭地区23个县市区为研究区,从土地、人口、经济三方面构建农村空心化的测度框架及指标体系,综合运用熵值法、多指标综合评价法和多元回归分析等方法对农村空心化进行测度,揭示农村空心化的空间地域分异特征及形成机理。结果表明:(1)长株潭地区土地空心化呈现由中心城市向外围逐渐减小的特征;人口空心化呈现出中部核心区高,北部低的特征;经济空心化的高、低分布与人口空心化的低、高分布在空间上具有较大的相似性特征。(2)综合空心化空间分布呈现出不均衡发展的态势,以中、低等级为主,空间分布由中心城市向东西两侧的外围地域逐渐减缓的特征,与中心城市的距离远近对空心化等级的空间分布具有较显著影响。(3)农村空心化是区域多种因素综合作用的结果,农民收入提高及区域经济发展、农村人口数量及就业结构变化是农村空心化的主导与直接影响因素,土地利用方式及效率的变化在一定程度上抑制了农村空心化程度的加剧。
[Abstract]:Taking 23 counties and cities in Changsha-Zhuzhou-Xiangtan area as the research area, the measurement frame and index system of rural hollowing are constructed from three aspects of land, population and economy, and the entropy method is used synthetically. The multi-index comprehensive evaluation method and multiple regression analysis were used to measure the hollowness in rural areas and to reveal the spatial regional differentiation characteristics and formation mechanism of rural hollowness. The results show that the land hollowness in Changzhou-Zhuzhou-Xiangtan area decreases gradually from the central city to the periphery, the population hollowness shows the characteristics of high core area in the middle and low in the north, the high and low distribution of economic hollowing and the low population hollowing. The spatial distribution of high distribution has the characteristics of larger similarity. 2) the spatial distribution of integrated hollowness shows an unbalanced development trend. The spatial distribution is mainly middle and low grade, and the spatial distribution gradually slows down from the central city to the peripheral areas on both sides of the east and west. The distance from the central city to the central city has a significant effect on the spatial distribution of the level of hollowness.) the hollowness in rural areas is the result of the comprehensive action of various regional factors, the increase of farmers' income and the development of regional economy. The change of rural population and employment structure is the leading and direct influencing factor of rural hollowness, and the change of land use mode and efficiency has restrained the aggravation of rural hollowness to a certain extent.
