| 摘 要： | 在湖北省县域交通优势度和经济发展水平综合测度的基础上,采用洛伦兹曲线、基尼系数、空间自相关等方法探究交通、经济发展的均衡性及空间集聚效益,计算其耦合协调度,根据两者相对发展度进行交通经济发展类型的划分。结果表明,湖北省县域交通优势度呈现出以武汉、襄阳和宜昌为核心的格局,西部山区交通优势度较低;县域经济以武汉市和宜昌市为核心,武汉市周边形成圈层状递减结构;各县市区交通优势度相对平均,交通发展均衡性优于经济发展;县域交通优势度和经济发展水平均呈正空间自相关,两者的高值聚集区和低值聚集区存在明显的空间重叠;湖北省交通与经济耦合度整体较高,协调性相对较低,绝大多数县市区交通优势未得到充分发挥。湖北省各县市区应充分发挥交通优势,促进经济快速发展。

| Abstract: | Based on the comprehensive evaluation of county transport superiority degree and economic development level of Hubei prov-ince, the balance and spatial agglomeration benefit between transport and economy were explored with Lorentz curve, Gini coefficient and spatial autocorrelation. Furthermore, coupling coordination degree between transport and economy was measured and the type of transport and economy was classified according to the relative rate between them. Results showed that:County transport superiority of Hubei province centered on Wuhan, Xiangyang and Yichang city, and it was high in the east and low in west;The centers of County economy located in Wuhan and Yichang and showed circular stepped spatial pattern around Wuhan decreasing gradually from the mid-dle;The transport superiority was evenly distributed in various counties and the distribution of transport is more balanced than econo-my;County transport superiority and economic development level presented positive spatial autocorrelation, and the High-High type and Low-Low type were consistent with each other;there was a high coupling degree and a low coordination degree between transport and economy, and most of counties didn' t make full use of traffic advantages. The transport superiority in each counties of Hubei prov-ince should be fully used to promote the county economy. |
