Protection model based on value assessment and vulnerability curve

Extreme weather has become one of the most serious challenges to humans' lives, its increasingly frequent occurrences affect the preservation and protection of many cultural buildings, to judge the cultural and historical value of a cultural building and its vulnerability to extreme weather, so as to further realize its preservation and protection. This paper establishes the historical and cultural value evaluation model and the vulnerability curve of cultural heritage buildings based on the AHP-Field method, Mann-Kendall test and quintile regression respectively. Taking Fujian Tulou as an example, we obtained the historical and cultural evaluation system and the vulnerability curve affected by heavy rain, and comprehensively considered the relationship between the two, and obtained comprehensive measures to protect Fujian Tulou buildings. Make feasible suggestions on how to protect ancient buildings in the case of heavy rain and provide reference for the evaluation and protection of other regions.
