我国能源强度空间分布的集聚性分析

Cluster Analysis of Spatial Distribution of China's Energy Intensity

中国分省能源强度空间分布地图显示出较大的地理空间聚集,能源强度自东南向西北地区逐渐增大。能源强度空间分布与能源资源禀赋分布十分类似。因此,提出命题"能源资源越丰沛,能源强度越高"。空间自相关检验揭示了省域能源强度存在着显著的空间依赖性,Moran散点图显示了能源强度水平类似的省区有相对集中的趋势,形成一种高-高、低-低各自相互吸引,高-低、低-高相互排斥的空间联系结构。

Through geographical map of energy intensity of provincial level,there is obvious space clustering and higher energy intensity is concentrated on economically undeveloped or energy resourceful regions.Therefore,the paper hypothesized that the more energy resourceful,the high energy intensity.The result of spatial autocorrelation test indicates that energy intensity presents spatial interdependence to some degree among Chinese provinces.The Moran scatter-plot displays that the comparatively centralized phenomenon tend to be occur in the province with parallel energy intensity,which is a spatial linkage structure that is attracted by high-high or low-low regions and repelled by high-low or low-high regions.
