Taking transportation infrastructure level and transportation smooth degree to other regions into consideration, choosing 8 indexes, including road density, railway density and distance from the road, etc. , this paper established the transportation ability index model firstly. By using the model and geographic information system technology, this paper then systematically evaluated the transportation ability of China in 2005 at county and province levels, so as to bring some scientific references and policy-making supports to the transportation planning and population development planning of China. The results showed that: ⑴ at county level, the transportation ability of counties within China in 2005 was significantly different, demonstrating a spindle shape in general. The spatial distribution presented a tendency downward gradually from coastal regions to inland regions. Compared with poverty-stricken areas, the transportation ability of urban areas were much better, and the transportation density difference was notable. ⑵ at province level, the transportation ability of provinces in 2005 was also significantly different, presenting a distribution of "high in east, low in west" in general; Transportation density difference was also notable between different levels, and the transportation supporting ability of western provinces was inferior. Thus, our government should make great efforts to improve the transportation condition in western China, so as to narrow the economic development gap to realize the coordinated development within different regions of China.
