兰州市安宁区彩钢棚空间分布特征及分析

Research on the Spatial Distribution of Color Steel Sheds in Anning District, Lanzhou City

基于平均最近邻、标准差椭圆、核密度等分析方法,研究了用于民用临时住房的小型彩钢棚和工业用大型彩钢棚的空间分布特征。实验结果表明,安宁城区小型彩钢棚、大型彩钢棚在空间中都呈聚集性分布,且两者分布方向为东南-西北轴向,但彩钢棚在不同区域的分布密度却有明显差异。总体反映出安宁城区结构深受地理环境、交通状况以及政府决策的影响,城市的经济发展仍相对滞后,城区内部亟待改造升级。

This paper used the average nearest neighbor index, the standard deviational ellipse, and the kernel density estimation method to study spatial distribution of small color steel sheds and large color steel sheds. The results show that the small and large color steel sheds are all aggregated, and their distribution direction are southeastnorthwest axis, but color steel sheds have different density in different areas. These characteristics reflect that Anning District is deeply affected by the geographical environment, traffic conditions and government decision. The city's economic is still lagging behind, and urban inner needs to be reformed and upgraded.
