辽西地区中心地等级关系和空间结构研究

Research on Level Relationships and Spatial Structure in Area of Western Liaoning

将辽西地区按照县级以上行政单位划分为21个中心地,以辽西地区中心地系统为研究对象,运用主成分分析法和综合打分法,测度各城市的中心性,并据此对辽西地区中心地进行等级划分与空间结构、功能关系分析。辽西地区中心地可划分为四个等级,其具有等级间差距大,同级间较均衡的特征。辽西地区中心地的空间结构并不严格属于克氏中心地理论中的任何一种,具有一级中心地与四级中心地南北带状分布,二级中心地沿海—内陆对应分布、结构紧致,三级中心地联结一级中心地与底层中心地的结构特征。其形成主要受到宏观政策、海洋的切割作用、与环渤海其他区域联系的影响。为建立合理、高效的中心地网络,辽西地区应积极参与外部区域的协作和联系;同时增强区域整体竞争力,协调区域内部的产业布局和基础设施建设,巩固锦葫城市群的中心作用;加强底层中心地对中心地网络的贡献。

The western Liaoning, as the research object, is divided into 21 central places based on administrative units which above country level in this study. The research will use analysis methods including principal component analysis and comprehensive marking method to divide the study area into 4 grades and to analyze the spatial structure of the study area. The spatial structure of western Liaoning has characters as follow： （1） Grade one and grade four forms zonal distribution; （2） Grade two have a compact structure and locate by the coast and in the inland area; （3） Grade three link high-grade ones and bottom-grade ones as connections. The characters above are controlled by comprehensive factors of many aspects. Micro policies, cleavage action by the Bohai Sea, resource and economic connection with other regions, such as the Bohai Rim, are the most important function factors to form the spatial structure in western Liaoning. To construct the central places system as a more reasonable and more effective spatial structure, attention should be paid to coordinate the resource distribution and industrial layout to void unnecessary internal competition. Besides, the western Liaoning area would be better participate in regional cooperation more actively. Furthermore, to exert central places＇ merit will give a great help, such as to improve the central function of high-level central places and to stimulate contribution of bottom-level central places.
