| 摘 要： | 运用城市首位律、位序-规模法则、城市中心性分析三江平原城镇体系的规模结构.从城镇空间分布、城镇空间集聚性和城镇空间联系三方面分析三江平原城镇体系的空间结构.结果表明:三江平原城镇体系城市首位度不高,大中城市规模相差较小;鸡西市的人口规模大于佳木斯市,但佳木斯的城市中心性强于鸡西;三江平原已经形成了以佳木斯和鸡西为中心的双核结构,但中心城市经济综合水平较弱,对外经济联系不强;以佳木斯为中心的城镇体系空间结构优于以鸡西为中心的城镇体系,但城市集聚性小于以鸡西为中心的城镇体系.最后针对三江平原城镇体系存在的主要问题提出优化措施.

| 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. |
