摘　　要：黑龙江省三江平原垦区是中国耕地规模最大的连片农垦区和第三大区际商品粮供应基地。近年来,随着这一地区工业化和城镇化进程的加快,如何科学的选择和建设区域的中心城市成为该区完善区域城镇体系和推进城镇化进程的紧迫任务和现实课题。基于此,应用改进的引力模型来计算县级单位与农场间的空间联系强度,界定出各县级单位的腹地范围,明确三江平原垦区的中心城市;以各农垦分局为研究单元,研究各农垦分局的碎化程度;通过明确县级单位拥有农场腹地数目,确定各农垦分局的中心城市;结果发现建三江、虎林、富锦、友谊和密山等宜作为三江平原垦区的中心城市;提出通过壮大中心城市的综合实力、推动场县共建和深化对外合作等措施来推动三江平原垦区城镇化进程。The Sanjiang plain reclamation area of Heilongjiang Province is the largest continuously arable area and the third-largest interregional commodity grain supply base of China. Recently, with the acceleration of regional industrialization and urbanization, the Sanjiang plain reclamation area faces challenges such as how to choose and construct regional central cities to build a reasonable urban system and promote the local urbanization process. Hence, the article focuses on choosing central cities in the Sanjiang plain reclamation area of Heilongjiang Province. The research content includes the following parts. Firstly, this research uses the modified gravitational model to calculate the spatial linkage capacity of the 24 county-level units(including 20 counties and 4 reclamation bureaus) to identify the hinterland delimitation of each county-level unit. Secondly, based on the former result, this article further studies the spatial structure features of each reclamation bureau by measuring the metropolitan fragmentation index. Thirdly, this article suggests that Jiansanjiang, Hulin, Fujin, Youyi and Mishan etc can be cultivated as potential central cities of each reclamation bureau. Last but not the least, in order to promote the urbanization process of the Sanjiang plain reclamation area, this research proposes that the Sanjiang plain reclamation area should improve the comprehensive strength of central cities, strengthen the cooperation relationship between state farms and local governments, and deepen the local opening-up degree.
