Effects of extreme precipitation on spatial heterogeneity of net primary production in Fujian Province
The interaction between vegetation carbon dynamics and extreme precipitation changes is significant.Exploring how vegetation net primary productivity(NPP)that characterizes carbon dynamics respond to extreme precipitation events is crucial for climate change adaptation strategy research of regional ecosystems.This study,based on NPP data from 1985 to 2015,utilized a Geo-detector to investigate the impact of extreme precipitation factors on vegetation NPP at different altitudes in Fujian Province.The results indicate that:1)NPP shows an overall increasing trend,with its spatial distribution correlated with altitude.2)From a single-factor perspective,the maximum one-day precipitation significantly influences the spatial pattern of NPP below 200 m in altitude,while precipitation intensity significantly affects the spatial pattern of vegetation NPP above 200 m in altitude.3)In terms of factor interaction effects,the interaction between precipitation intensity and maximum one-day precipitation has a more significant driving effect on the spatial pattern of NPP.This study deepens the understanding of the impact mechanisms of extreme precipitation on NPP in Fujian Province at different altitudes,providing insights for the classification,protection,and restoration of vegetation ecology in the region.
