Abstract: Regional spatial structure has been studied in depth. But the spatial structure in a basin has not been studied systematically,although basin is one of the important district units for regional economy. This paper introduces the coreperiphery structure model of Skinner. Then, the characters and evolutionary progress of spatial structure in Ganjiang River have been analyzed.The results show that the Ganjiang Basin can be divided into three parts as core region, transition region and periphery region. All of these certify that Ganjiang Basin has apparent coreperiphery structure.Mountain, river and lake (MRL) consist of the three factors of Ganjiang Basin, and there are close connections between them. Ganjiang river as the maximum river of Ganjiang Basin flows from southern to northern of Jiangxi and infuses Poyang Lake which is the maximum freshwater lake in China. Mountain, river and lake are connected by Ganjiang River as a whole and form an ecological system. So we must take MRL as organic entity and construct it step by step when we harness ecological environment, and exploit resources, and allocate industry and agriculture.

Key words: basin, coreperiphery structure model, Ganjiang Basin
