咸阳市单位GDP能耗空间分异特征分析研究

以地统分析为基础,在GIS技术平台下分析"十一五"期间咸阳市各区县单位GDP能耗空间分异特征.单位GDP能耗重心与几何中心偏移较大,在西北-东南向最为分散,不均衡性大;全局相关性属随机分布模式,自相关性一般,局部相关性呈区域性分布,具有较强相关性的区域为东南方向的泾阳和三原县、西北方向的彬县和长武县;微弱相关性区域主要分布在旬邑县、咸阳中南部地区;5年间单位GDP能耗重心向西北方向偏移,向高纬度、低经度方向移动.

Spatial Differential Features Analysis onEnergy Consumption Per Unit GDP in Xianyang

Based on the analysis of the geographical statistic and the technology of geographical information system, the spatial differential features of the energy consumption Per Unit GDP was analyzed during the eleventh five-year plan period.The weighted mean center of the energy consumption Per Unit GDP is more moved than the geometric center, the most scatter turns on the direction of northwest-southeast, it is lack of uniformity.The whole spatial autocorrelation belongs to a random pattern, which is a weak spatial autocorrelation.The analysis of partial correlation shows regional distribution, which displays the Jingyang and Sanyuan in the northeast, Binxian and Changwu in the northwest with the stronger autocorrelation;the weak autocorrelation turns out Xunyi, the middle-south of Xianyang.The weighted mean center of the energy consumption Per Unit GDP between the five years moved on the northwest, to the high latitude and low longitude.
