中原文化遗产时空分布特征与影响因素——以河南省文物保护单位为例

Spatio-temporal Distribution Characteristics of Cultural Heritages in Central Plains and Its Influence Factors:A Case Study of Henan Historic Reservation Units

采用ArcGIS10.7的核密度分析、最邻近指数、地理集中指数以及SPSS软件的Pearson相关系数分析等方法,对河南省文物保护单位时空分布特征及其影响因素进行了探究。结果表明:(1)河南省文物单位数量宋元明清时期最多、秦汉至隋唐时期最少;(2)不同时期文物保护单位的核密度聚集特征具有明显差异,随着时间的推进,由最早的豫中地区向豫北、豫东地区聚集分布;(3)受地形地貌和政治文化影响,河南省文物保护单位多分布在低海拔、近河流、近路网的地区,不同时期的选址和政治制度也会对文物保护单位的分布产生影响。

In this thesis,we used the methods of kernel density analysis,nearest proximity index and geographical concentration index analysis in ArcGIS10.7 as well as Pearson correlation coefficient in SPSS software to explore the spatio-temporal distribution characteristics of historic reser-vation units in Henan Province and its influence factors.The results show that①the number of historic reservation units in Henan Province is the largest in the Song,Yuan,Ming and Qing Dynasties,and the smallest in the Qin,Han,Sui and Tang Dynasties.②There are obvious differences in the kernel density aggregation characteristics of historic reservation units in different periods.With the passage of time,they gather and distrib-ute from the central subregion of Henan Province to its northern and eastern subregions.③Under the influence of topography,landform and polit-ical culture,historic reservation units in Henan Province are mostly distributed at low altitudes,near rivers and near road networks.The location and political system of different dynasties also affect the distribution of historic reservation units.
