Abstract:

Based on the theory of resources field and potency, the obtainable data on coal resources potency, coal task potency and coal resources-task potency of China’s 30 provinces (autonomous regions or municipalities) from 1986 to 2010 are calculated, and the characteristics of their temporal and spatial changes are analyzed in this paper. The result demonstrates that 30 provinces in China can be classified into three types: coal field source zone, coal field collection zone and basic equilibrium zone. And then the basic characteristics of coal resources spatial allocation are concluded, and the rationality of coal resources spatial allocation in China in 2010 is evaluated. Several conclusions are obtained as follows:
Firstly, the coal resources potency began to change before 2000, and the coal resources has tended to centralize in Shanxi and Henan, but shifting from the northeast to the northwest with the elapse of time. Secondly, coal task potency maintains relatively stable, only accompanying with a small scale change, presenting similar spatial distribution with coal resources potency in general. Thirdly, most provinces need to transfer coal from other provinces, coal resources-task field tends to gather in the eastern and southern coastal areas and regions of Shanxi, Shaanxi and Inner Mongolia. At present, "S-shaped" input zone mainly consists of the eastern and southern coastal areas, and the Bohai Rim and "V-shaped" output zone mainly covering Shanxi, Shaanxi and Inner Mongolia have been formed basically. Fourthly, coal spatial allocation types of China’s 30 provinces are identified as field source zone (6 provinces), field collection zone (19 provinces) and basic equilibrium zone (5 provinces). There are significant regional differences in the direction and intensity of coal spatial allocation, phenomena of spatial polarization strengthens the regional function and clarifies the regional division of labour. Fifthly, China’s coal spatial allocation is reasonable in general, but due to irrational allocation in direction and intensity in individual regions, the problems of too much output from source zone and excessive input in collection zone still exist in several regions.

Key words: coal resources potency, coal task potency, coal resources-task potency
