The Temporal and Spatial Distribution Characteristics of Shanxi Ancient Capital Sites and the Influencing Factors of Natural Environment
The capital city is the political,economic and cultural center of a country and a nation.The number and characteris-tics of ancient capital sites in a region are important indicators of the historical development of the region.In this paper,the spatial and temporal distribution characteristics of 47 ancient capital sites in Shanxi Province and the influencing factors of natural environ-ment were discussed by means of historical records review and ArcGIS software spatial analysis.The results show that the ancient capital sites in Shanxi Province are"agglomerated"and evenly distributed in all prefecture-level cities in Shanxi Province;its loca-tion and quantitative characteristics change with time.In space,it is manifested as'from south to north'.In quantity,it is manifested as more wars and less peacetime;the ancient capital sites are mainly distributed in basins,intermountain valleys and plateau basins at an altitude of 106~1101 m,with a distance of 0-5 km from the water,a slope of 45°~315°and a slope of 0°~3°;there is a strong coupling relationship between climate change and the number of ancient capital sites.It shows that the natural environment is an important factor affecting the temporal and spatial changes of the ancient capital sites in Shanxi Province.
