河南黄河区域文化遗产时空间分布特征——以不可移动文物为例

Temporal and Spatial Distribution Characteristics of the Cultural Heritage of the Yellow River in Henan Province:Taking Immovable Cultural Relics as Example

针对现阶段黄河文化遗产保护的相关研究与实践,对河南黄河区域的所有不可移动文物进行数据汇总,构建该区域的不可移动文物地理空间数据库。使用平均最邻近比率与核密度估计的方法对河南黄河区域各时期重要文物保护单位与不可移动文物的空间分布特征进行比较,分析造成其时空间变化与不同等级不可移动文物分布异质性的原因。结果表明:(1)河南黄河区域不可移动文物在时间分布上具有良好的连续性;(2)不同时期河南黄河区域不可移动文物空间布局整体上均呈现较为明显的集聚特征,呈现突出的时空异质性;(3)不同级别不可移动文物的时空分布在特定时期具有明显的异质性。

This research summarized all the immovable cultural relics and built a geospatial database of immovable cultural relics in the Yellow River area of Henan.The average nearest neighbor ratio and nuclear density estimation method were adopted to compare the spatial distribution characteristics of major historical and cultural sites and all immovable cultural relics in various periods in the Yellow River area of Henan,and analyzed the reasons for the temporal and spatial changes and the heterogeneity of the distribution of immovable cultural relics of different levels.Based on which,the following conclusions can be drawn:Firstly,the time distribution of the immovable cultural relics in the Yellow River area in Henan has a good continuity;Secondly,the spatial layout of the immovable cultural relics in the Yellow River area in Henan during different periods showed obvious agglomeration characteristics as a whole,and outstanding temporal and spatial heterogeneity;Thirdly,the temporal and spatial distribution of immovable cultural relics of different levels has obvious heterogeneity in a specific period.
