Abstract:Based on the compiled data from the National Basic Meteorological Station in Guanghan City from 1994 to 2023,a comprehensive quantitative analysis was conducted on the key meteorological factors affecting the temperature,relative humidity,and wind speed of Sanxingdui cultural relics.Research has shown that the region has undergone a significant long-term warming process,especially during the summer when the temperature increase intensifies.The daily temperature range has been expanding year by year,increasing the structural risk caused by the thermal expansion and contraction of cultural relics.In addition,fluctuations in relative humidity and wind speed pose a threat to the preservation environment of cultural relics.To address the above challenges,the article proposes an optimization strategies for ground meteorological observation stations.By encrypting the station layout and adding observation stations for special environments,a more refined and diversified meteorological monitoring network has been constructed,significantly improving the monitoring capacity of the Sanxingdui Ruins area.
