Spatial Distribution of Population in Russia and Its Evolution
以俄罗斯83个联邦主体为对象，使用Getis-Ord Gi*指数和局部莫兰指数分析1990-2012年欧洲部分人口分布的时空演变，发现人口集中于欧洲地区，伏尔加地区为热点，西伯利亚等地为冷点。
Russia is a typical small sparsely populated country which has the world's largest land area.The country's total population decreased faster population situation continued to deteriorate after the disintegration of the USSR in 1991.At present the Russian federal subjects by the 83 units,which are the first class administrative units of Russia and play an important role in the process of Russia's social and economic development.Firstly,with the Russian 83 federal subjects as the object to analysis the Russian's population size structure of the overall scale in Russia.TheGetis-OrdGi * index and The Local Moran's I index are then employed to investigate the spatial-temporal evolution of population distribution in Russian's European region from 1990 to 2012.Major conclusions can be drawn as follows:( 1) The population distribution in Russia is unbalanced;Russia's population distribution is mainly concentrated in the regions of European Russia,whilesparsely populated eastern region.( 2) There is a certain spatial relevance of population distribution in Russia's Europe region,hotspots in the Volga region and southern region of Urals;Western Siberia,Northwestern Federal District,as well as the Southern Federal District and the North Caucasus Federal District Population cold spots forming cold spots district.( 3) Population concentration in the region of St.Petersburg,Nizhny Novgorod,and Kursk State for the vertex of the triangle,and the interactionhas become strongerin the high concentration triangle area.
