内陆省份交通门户与门户经济联系的协调性

Coupling coordination between development of transport gateways and their economic connections in inland provinces

首先建立内陆省份“交通门户—腹地”系统;接着基于对交通场站能级和位置的地理信息挖掘,确定区县单元的场站负荷并利用规模位序法则识别各地市的交通门户区县及其建设水平;最后调用潜力模型及耦合协调度模型,研判内陆省份交通门户建设与门户经济联系的协调发展态势.将以上研究方法应用于陕西省的实证分析后,其有效性得到验证,同时得出以下结论:(1)陕西省交通门户建设与门户经济联系的协调水平具有向西安市单中心极化的特征;(2)陕西省10个地市的协调水平在整体上呈现出“域外强于域内”的差异性;(3)陕西省部分地市较差的域内或域外协调水平表现可归因于具体的交通及经济条件约束.

The“transport gateway-hinterland”system of inland province was established at first.Both capability and location of all the transport stations in the system were then determined through geographic information mining so that the load intensity of transport stations for each county unit in the system was calculated.Moreover,transport gateway counties in the system were found out and their developing levels were also identified according to arranging load intensities of transport stations by Rank-Size rule.Finally,the potential model and coupling coordination degree model were employed to analyze coordination between developing levels of transport gateways and their economic connections in inland province.After applying the above research methods to the empirical analysis of Shaanxi Province,its effectiveness is verified and the following results are obtained.①The coordination level between the construction of Shaanxi Province′s transportation gateway and the economic connection of the gateway is characterized by polarization towards a single center in Xi′an.②The coordination level of 10 cities in Shaanxi Province shows the difference of“the outside region is stronger than the inside region”on the whole.③The poor intra-regional or extra-regional coordination level of some cities in Shaanxi Province can be attributed to specific traffic and economic constraints.
