运用标准差椭圆和空间自相关分析方法,对我国交通运输流在2005-2013年间发展的时空演化及城市间空间关联性进行了相关测度。结果表明:2005-2013年间,交通运输流发展重心向东移动后持续西移,发展空间收缩后扩张,发展轴线顺时针偏转后逆时针偏转,南北方向收缩,东西方向扩张,表明国际市场的萧条影响了交通运输业的发展,国内市场作用开始显现;从发展密集性变化看,2008年密集性增速迅猛,2012年后明显降低,说明靠投资带动的交通运输业的发展不可持续,这种"假性"提升必定会转入中低速度;我国交通运输流的发展存在一定的空间正相关性,但是相关性较低,同时各类集聚区规模随着国家投资及地区战略的实施发生着动态变化。
Standard deviation and spatial autocorrelation analysis method were used to research the spatial and temporal evolution and spatial autocorrelation of China's transportation industry. The resuhs show that during 2005 -2013, the focus of the transportation industry developed from the east to the west region; the development space contracted firstly, and then expanded. Development axis deflected clockwise firstly, and then counterclockwise. North-south direction presented contraction, and eastwest direction presented expansion. These show that the depression of the world financial crisis had affected the development of China's transportation industry. The transportation industry development in the domestic market will be more and more important. From opment which rely on the investment is not sustainable. This "false" ascension is bound to be transferred to a low speed. The development of China's transportation industry exist certain spatial correlation, but the correlation is low; scales of all kinds of agglomeration districts changed with the dynamic changing of national investment and regional strategy.
