摘要

为缓解城市建设用地需求压力，提高城市土地利用水平，对滇中城市群建设用地结构的时空演变进行了研究。首先利用ArcGIS 10.3软件提取滇中城市群建设用地数量，然后利用标准差椭圆、标准距离和重心迁移模型对其空间特征进行分析。实验表明，滇中城市群建设用地扩张方向以东北方向最为突出，东南方向则呈现相对减弱趋势。

The temporal and spatial evolution law of construction land structure in central Yunnan urban agglomeration based on GIS

In order to reduce the pressure of urban construction land demand and improve the level of urban land use, this paper studies the temporal and spatial evolution of the construction land structure in the central Yunnan urban agglomeration. Firstly, ArcGIS 10.3 software was used to extract the construction land quantity of the urban agglomeration in central Yunnan, and then the standard deviation ellipse, standard distance and gravity centre migration model were used to analyse its spatial characteristics. Experiments show that the northeast direction is the most prominent direction of construction land expansion in the central Yunnan urban agglomeration, while the southeast direction shows a relatively weakening trend.
