Abstract: Based on 819 survey data of Southern Shaanxi, the structural equation model was established to analyze the influencing factors and action paths of climate change risk response perception in Southern Shaanxi. The results showed that perception of climate change effect, human-earth concept, education level, climate change concern degree, perception of industrial structure adjustment impacted response status. People's concept of man-land and risk affect people's perception of climate change response by influencing their perception of the causes of climate change. There were 19 pathways and 9 causal pathways for climate change risk response in Southern Shaanxi. The path model was spatially different. The unmediated path model was showed in Hanzhong city and Shangluo city, the mediated path model was showed in Ankang city, which was consistent with the whole Southern Shaanxi region. Based on th e geographical detector and structural equation model path, the key factors influencing climate change risk perception in Southern Shaanxi were explored, some suggestions were put forward to improve the level of climate change risk response perception.

Key words: Southern Shaanxi, climate change, risk response perception, impact path, influencing factor
