Distribution Characteristics and Influencing Factors of Cultural Heritage in the Upper Reaches of the Yangtze River
Cultural heritage is the carrier of Chinese culture,cultural relics protection unit is an out-standing representative of cultural heritage.Taking a total of 2 600 national and provincial cultural relics protection units in the upper reaches of the Yangtze river as research objects,the spatio-tem-poral evolution and characteristics of these units are studied by using the nearest neighbor index,nu-clear density estimation,gravity center migration and other spatial analysis methods,and based on the 20 km x 20 km uniform grid,ESDA and Geographical detector models are used to explore their spatial correlation patterns and factors affecting spatial distribution.The results show that:1)The cultural relics protection units in the upper reaches of the Yangtze river experienced a long time,mainly concentrated in the three periods after the Song and Yuan dynasties;2)Firstly,the units of cultural relics protection in the upper reaches of the Yangtze river as a whole present the spatial characteristics of east-west sparse and contiguous distribution;Secondly,the spatial distribution of cultural relics protection units in different periods and of different types of cultural relics protection units is highly concentrated.Moreover,the spatial distribution of cultural relics protection units has a strong spatial autocorrelation,it's significant areas are mainly H-H types;and finally,the trans-fer of the center of gravity is concentrated in Sichuan Basin,and the migration distance shows a fluc-tuating trend;3)A total of 8 variables,of natural and human factors affect the spatial distribution of the units of cultural relics protection,among which the indicators of human factors are more explana-tory.
