【摘要】：运用Arc GIS空间分析、交通优势度模型和耦合协调度模型等方法,对云南省县域城镇化与交通优势度的时空协同性演化特征进行系统分析。研究表明:(1)城镇化与交通基础设施相互促进又相互制约,存在正负双向反馈;基础设施建设滞后、城乡二元结构格局、城市空间无序蔓延是导致两者耦合协调空间差异的主要因素。(2)2000~2014年云南省整体县域城镇化水平普遍较低,约90%的县域处于城镇化起步阶段。(3)云南省县域交通优势度整体水平逐年提升,但空间分异特征显著。(4)2000~2014年期间云南省县域城镇化与交通优势度的耦合协调水平虽大幅提升,但整体协调度仍然偏低、空间分异特征依然突出。
[Abstract]:By means of Arc GIS spatial analysis, traffic dominance model and coupling coordination degree model, this paper makes a systematic analysis of the spatial and temporal cooperative evolution characteristics of urbanization and traffic dominance in the county area of Yunnan Province.The study shows that urbanization and traffic infrastructure promote and restrict each other, and there are positive and negative bidirectional feedback; infrastructure construction lags behind, and the urban-rural dual structure pattern,Urban spatial sprawl is the main factor leading to the coupling and coordination of the spatial differences. The urbanization level of the whole county in Yunnan Province from 2000 to 2014 is generally low.About 90% of the counties are in the initial stage of urbanization.) the overall level of the county traffic dominance in Yunnan Province is increasing year by year, but the coupling and coordination level of the urbanization and the traffic dominance in the county area of Yunnan Province during the period from 2000 to 2014 has been greatly improved.However, the overall degree of coordination is still low, spatial differentiation features are still prominent.
