【摘要】：坦桑尼亚是中国"一带一路"战略的重要辐射点,中国已成为坦桑尼亚第一大贸易伙伴。本文基于坦桑尼亚全国人口普查资料及分地区统计数据,运用人口密度分析法、人口分布集中指数、人口重心模型和人口偏移增长模型,分析了坦桑尼亚自20世纪80年代末经济变革以来人口分布的空间格局及演变特征。研究结果表明:(1)坦桑尼亚人口分布以中央铁路线为界,呈现"南疏北密"特征;(2)1988-2002-2012年间,人口分布不均衡发展的态势不断增强,人口分布重心始终处于中部偏北地区,且有继续北移的趋势;(3)人口向城市地区集聚是人口再分布的主要过程,中心城市的人口集聚能力不断增强,达累斯萨拉姆省始终处于正向增长的绝对优势地位,以致周边地区出现明显的人口偏移负增长;(4)铁路和港口等基础设施对人口集聚的作用明显。上述结论对中坦在基础设施建设、住房建设及公共服务方面的合作具有重要意义。
[Abstract]:Tanzania is an important radiation point "Chinese Belt and Road Initiative" strategy, China has become Tanzania's largest trading partner. The Tanzania national census data and sub regions based on the statistical data, using population density analysis, index of the population distribution, population migration and population gravity model growth model, analysis of Tanzania since the end of 1980s since the economic reform the spatial pattern of population distribution and evolution characteristics. Research results show that: (1) the population distribution of Tanzania to the central railway line for the sector, showing "South North sparse dense" characteristics; (2) 1988-2002-2012 years, the uneven distribution of population development trend of growing population center is always in the north central region, and continue to move northward the trend; (3) the population gathers to the city area is the main process of population distribution, agglomeration ability of the central city population growing up tired Salam, always in the positive growth of the absolute dominant position, the population migration negative growth significantly so that the surrounding area; (4) railway and port infrastructure obviously on the population agglomeration effect. The conclusion of Tanzania in the infrastructure construction, has important significance for housing construction and public service cooperation.
