文化廊道空间界定之CCSPM模型构建——以滇西南跨境文化廊道为例

Construction of CCSPM Model for Spatial Definition of Cultural Corridor:A Case Study of Cross-border Cultural Corridor in Southwest Yunnan

基于景观信息链理论,按照识别文化基因、确定文化点、模拟廊道空间的过程,结合阻力模型及原理,运用ArcGIS工具从文化点对廊道文化的传播重要性、文化点的区域影响力、各文化点的空间关系以及自然环境对文化传播的约束等4个方面,构建出CCSPM(cultural corridor spatial pattern model)模型,并运用该方法界定滇西南跨境文化廊道的空间范围。结果显示:(1)滇西南跨境文化廊道的文化元素影响范围沿交通线集聚但空间差异性较大;(2)滇西南跨境文化廊道总体格局、分布趋势和历史进程大致相符,模型能较有效地表征文化廊道空间范围。该方法为文化廊道空间研究提供新的研究思路,进而为分析廊道内部的文化连接方向和程度及文化遗产的整体保护与开发提供空间信息支持。

Cultural corridor emphasizes the spatial and temporal scope of cultural diffusion and the overall development of realistic region.It is very important to define the spatial scope of corridor reasonably,which is the basic work of the related research and conservation strategy of linear cultural heritage.Based on the theory of landscape information chain,according to the process of identifying cultural genes,determining cultural points and simulating corridor space,combined with resistance model and principle,the CCSPM model is constructed by using ArcGIS tools from four aspects:the importance of cultural points to corridor culture transmission,the regional influence of cultural points,the spatial relationship of cultural points and the constraints of natural environment on cultural transmission,and the spatial scope of cross-border cultural corridor in Southwest Yunnan is defined by this method.The results show that:1) The influence range of cultural elements in cross-border cultural corridor in southwest Yunnan is concentrated along the traffic line,but the spatial difference is large;2) The overall spatial pattern and distribution trend of cross-border cultural corridors in Southwest Yunnan are roughly consistent with the historical process,and the model can effectively represent the spatial scope of cultural corridor.This method provides a new research idea for the spatial study of cultural corridor,and then provides spatial information support for analyzing the direction and degree of cultural connection in the corridor and the overall protection and development of cultural heritage.
