基于GIS的滇中城市群空间结构效益优化研究

在ArcGIS软件和云南基础地理数据支持下,对滇中城市群空间结构效益进行初步解析.结果表明：滇中城市群的突出优势在于人口规模大,经济发展水平较高,经济发展综合指数和城市化综合指数较大,其中昆明和玉溪的经济发展与城市化协调度较高,同时表现出空间差异;滇中城市群紧凑度较高,城市交通优势度相对较高,可达性较好,重要城市之间的空间联系较为紧密,但城市数量较少,规模效益相对欠缺.以实现城市群空间结构效益最大化为目标,在综合分析的基础上提出了滇中城市群方案.

OPTIMIZATION OF SPATIAL STRUCTURE BENEFITS OF YUNNAN CENTRAL URBAN AGGLOMERATION BASED ON GIS

In the support of ArcGIS software and basic geographic data of Yunnan, preliminary analysis the spatial structure benefits of central Yunnan urban agglomeration. The results showed that：Fist, the highlight the advantages of central Yunnan urban agglomeration is large population, a higher level of economic development, greater economic development and urbanization Composite Index. In Kunming and Yuxi, economic development and urbanization coordination degree is higher, but have spatial differences between them. Second, in central Yunnan the degree of compact is high, the urban traffic accessibility is relatively better, degree of is better, and spatial links between major cities are more closely. But the number of cities is less, and the scale benefit is lack. In order to achieve maximum benefit, proposed the program of central Yunnan urban agglomeration on the basis of a comprehensive analysis.
