2000年以来河西走廊文化遗产灾害风险评估及空间分异驱动因素分析
Disaster risk assessment and drivers of spatial differentiation of cultural heritage in the Hexi Corridor since 2000
摘要
Abstract
The Hexi Corridor is a major concentration area of Silk Road cultural heritage in China,where heritage sites have long been affected by multiple factors,including drought,aeolian sand activity,land-use change,and the deterioration of heritage materials.Taking 234 cultural heritage sites in Wuwei,Jinchang,Zhangye,Jiuquan,and Jiayuguan within the Hexi Corridor as the research objects,this study constructed a disaster risk assessment index system from three dimensions:heritage vulnerability,hazard intensity,and environmental sensitivity.Based on multi-source data and the entropy weight method,the disaster risk of cultural heritage sites in 2000,2005,2010,2015,and 2020 was evaluated.The geographical detector model was further used to identify the dominant factors and interaction effects influencing the spatial differentiation of comprehensive risk.The results show that the vulnerability of cultural heritage sites in the Hexi Corridor varies markedly by heritage type,with highly vulnerable types such as ancient sites and ancient buildings accounting for a relatively high proportion.Among the hazard factors,aridity and soil wind erosion modulus are important factors affecting external heritage risk,whereas water erosion risk is generally low.Environmental sensitivity is mainly controlled by geomorphic type,while land-use change plays a regulatory role in local sensitivity.Since 2000,the comprehensive risk of cultural heritage in the study area has been dominated by extremely low-and low-risk levels,although some heritage sites have shown an increase in risk level.Spatially,risk is generally higher in the western section than in the central and eastern sections.The geographical detector results indicate that geomorphic type has strong explanatory power for the spatial differentiation of comprehensive risk,and the explanatory power generally increases after factor interaction.Among all interactions,the combination of"land use × geomorphic type"shows the highest explanatory power,indicating that disaster risk to cultural heritage in the Hexi Corridor is jointly shaped by natural geographical conditions,drought and aeolian processes,land-use change,and heritage vulnerability.The findings provide a reference for zoning-based conservation,key monitoring,and risk prevention of cultural heritage in the Hexi Corridor.关键词
