摘要

Identifying the types of disasters and analyzing the distribution pattern of and the spatial correlation between villages and disasters are important prerequisite for the disaster prevention and mitigation of traditional villages.Taking Aba Tibetan and Qiang Autonomous Prefecture as an example and using the tools of kernel density evaluation and spatial statistics,this paper analyzes the distribution pattern of and the spatial correla-tion between traditional villages and typical geological disasters on the three spatial scales of Aba Prefecture,village agglomeration area,and village administrative area with necessary explanations.It concludes that most of the traditional villages in Aba Prefecture agglomerate in the middle-and high-level alpine gorges and some are clustered at either the border area or the central hinterland of counties;with the increase of maximum seismic intensity and frequency of earthquakes,it appears there is an increase of traditional villages and their trend of agglomeration,which implies an over-lap of the areas of dense traditional villages and high-density geological disasters,as well as the synchronous increase of traditional village density and geological disaster density;and the traditional villages in Aba Prefecture are affected by multiple disasters,in particular landslide and debris flow.Finally,the paper discusses the issue of disaster prevention and mitigation in the protection and development planning of traditional villages.
