Structure equation modeling (SEM) assessing the direct and indirect influences of driving factors on AR and HR. Blue and red arrows indicate negative and positive relationships, respectively. The numbers on arrows are standardized path coefficients, and arrow width is proportional to the strength of the relationship. *P < 0.05, **P < 0.01, ***P < 0.001
