摘要
采用变异系数、尺度方差、地统计分析、地理加权回归等方法,基于分县级、地级、省级三种尺度分析2000年和2010年我国人口半城镇化的区域差异及空间演变特征,研究发现:(1)半城镇化区域差异在三种尺度上均表现出逐渐扩大的态势;(2)尺度方差及其分解结果显示,尺度方差及其构成大小依次为县级、地级、省级,即尺度越小,尺度方差越大,对半城镇化区域差异的贡献份额越大;(3)空间格局研究表明,不同尺度区域半城镇空间差异显著,呈现出东西梯度发展格局,各尺度空间关联格局总体相对稳定,"High-High"类型集聚区大多分布于东南沿海地区,"Low-Low"类型集中分布于西部地区;(4)最后,将人口半城镇化格局演化的影响因素归结为三个方面:经济发展水平、人口流动与产业结构。
This paper employs coefficient variance, scale variance, geostatistical analysis, GWR model and spatial autocorrelation to calculate the population peri-urbanization rate so as to examine the changing trends and spatial patterns of regional inequalities in China at three spatial scales, i.e. province, prefecture and county. The results aresummarized as follows. ( 1 ) From the calculation results of Cvand Moran' s I, we find that the regional difference of peri-urbanization is gradually increasing at the three spatial scales since 2000; (2) The results of the scale variance show different patterns obviously. With the scale variance and its component statistic techniques, we discover that there is an increasing sequence according to the scale variances and their components, i.e. county, prefecture and province, which indicates that the scalar variance is lower at the smaller scale and the regional inequality at smaller scale contributes more to the whole regional inequality; (3) By using spatial analysis techniques, we find that local spatial autocorrelation patterns have been stable since 2000. The "High-High" type units tend to concentrate in the east coastal area of China. And the "Low-Low" type unites cluster in central and western China; (4) The driving force of the evolvement of population peri-urbanization in China can be identified through the following aspects : the economic levels, the population mobility and the industrial structure.
