【摘要】：作为中东大国之一,亦是中国战略合作伙伴的伊朗是"一带一路"中"新丝绸之路"经济带上的重要交通枢纽,科学合理测度其人口空间分布格局演变特征可提升对伊朗国内发展态势的认知,对加强中伊政治经济合作具有现实意义,也可丰富世界地理研究领域中东区域的典型案例。运用人口分布不均衡指数、重心分布、密度等指标,结合探索性空间数据分析和偏移-分享分析法等研判1986年~2016年伊朗人口分布空间格局演变特征,结果表明:伊朗人口空间分布极不均衡,人口主要集中在中央高原西北部、里海沿岸平原;人口密度整体上呈西北高东南低的特征,人口分布与自然地理环境条件、经济发展水平呈显著正相关;伊朗的人口流动以邻域地区和城市之间的流动为主,主要流向经济发达的北部和西北地区,这也与人口重心在西北地区的空间路径依赖惯性趋势吻合;伊朗人口分布的空间格局演化分异呈显著空间自相关性,人口密度较高和较低的区域均出现空间集聚特征,密度高高集聚区位于北部、西北部山地和德黑兰周边与中央高原交界处,且逐渐向东南方向延伸;密度低低集聚区主要分布于东部山地和西南地区,且变化甚微。
[Abstract]:As one of the great powers in the Middle East and a strategic partner of China, Iran is an important transportation hub on the "New Silk Road" economic belt in the "Belt and Road". Scientific and reasonable measurement of the evolution characteristics of population spatial distribution pattern can enhance the cognition of Iran's domestic development situation, strengthen the political and economic cooperation between China and Iran, and enrich the typical cases of the Middle East region in the field of world geography research. Using the index of population distribution imbalance, center of gravity distribution, density and so on, combined with exploratory spatial data analysis and offset-sharing analysis, this paper studies the evolution characteristics of Iranian population distribution spatial pattern from 1986 to 2016. The results show that the spatial distribution of Iranian population is extremely uneven, the population is mainly concentrated in the northwestern part of the central plateau and the coastal plain of the Caspian Sea, and the population density is generally high, southeast and low in the northwest, and the population distribution and the natural geographical environment conditions. There is a significant positive correlation between the level of economic development and the flow of population in Iran, mainly between neighboring areas and cities, mainly to the north and northwest regions with developed economies. This also coincides with the trend of spatial path dependence of population center of gravity in northwest China. The spatial pattern evolution and differentiation of Iranian population distribution show significant spatial autocorrelation, and the regions with higher population density and lower population density have the characteristics of spatial agglomeration. The area with high density is located in the north, the northwestern mountainous area and the border between Tehran and the central plateau, and gradually extends to the southeast, and the low density area mainly distributes in the eastern mountain area and the southwest area, with little change.
