Abstract:

By applying the laws of the primary city,rank-size rule, and urban centrality,we analyzed the scale structure of the urban system in Sanjiang plain,and then analyzed the spatial structure including urban spatial distribution,urban spatial agglomeration, and spatial linkage. The results show that urban primacy ratio in Sanjiang plain is low,and Jixi has larger scale than Jiamusi,but less urban centrality. The dual-core structure has formed based on Jiamusi and Jixi cities,but the economy level of the central city is low and the economic linkage is weak. The spatial structure of urban system in Jiamusi is better than that in Jixi,but urban spatial agglomeration is less. Finally,we analyzed the problems of urban system in Sanjiang plain and some policy recommendations are presented.

Key words: urban system, scale structure, spatial structure, Sanjiang plain
