Coal is a strategic resource of social and economic development in China.The distribution inequality of society-economy and coal resources determines the regional transportation of coal resources,which becomes the focus of many countries or governments.We simulated and discussed the flowing field and flowing pattern of coal resources in China,and drew these conclusions.1)Distribution and richness of coal resources decide the spatial pattern of coal outflow scale.In 1971,outflow regions concentrated in North China but shifted appreciably to Central and West China currently,and coal bases especially in Shanxi and Inner Mongolia become the main outflow regions.2)Distribution and size of economy and population decide the inflow scale of coal generally.Inflow region were concentrated in north coastal region in 1971 and expanded to southeast coastal region currently,especially port and industrial city have a great inflow scale.3)There are some diffused fields of coal flow whose centers and larger fields are located in North China but begin to expand to West Region currently,especially the diffused fields of Shanxi and Inner Mongolia have the strategic significance.There are also several concentrative fields,whose centers are located largely in north coastal region but begin to expand to southeast coastal region,most of which are ports,industrial cities and economic centers.4)Due to the dislocation distribution of the coal base and the coal-consuming region,there occurred the Water-Rail Multimodal Transport.Railways connecting with ports especially seaports transport a great deal of coal flow yearly and become the main coal-transportation corridors,such as Datong-Qinhuangdao Railway,Shenfu-Huahuang Railway,Lanzhou-Lianyungang Railway,Beijing-Shanghai Railway,Nanjing-Xi'an Railway.Most coal-loading ports are located in the north coast and the Yangtze River,especially Qinhuangdao Port,Tianjin Port and Huanghua Port with a large scale of loading coal,but most coal-unloading ports are located in the southeast coast.This discussion will help to investigate the demand and supply pattern of energy in China and regional economic relationship.
