Abstract:

Pomacea canaliculata is an important invasive alien species in China, posing a serious threat to the safety of wetland ecosystems. To effectively monitor and control P. canaliculata, this study utilized its current geographical distribution data in Zhejiang Province. Using the MaxEnt modle and ArcGIS software, we predicted its potential suitable habitats and analyzed the main environmental factors affecting its distribution by incorporating climate, elevation, and other variables. The results showed that the MaxEnt model performed well in predicting the geographical distribution of P. canaliculata in Zhejiang Province. The potentially suitable habitats were primarily located in the northern Zhejiang Plain, the Eastern Coastal Plain, and the Jinqu Basin, with an overall distribution pattern that was dense in the north and sparse in the central and southern regions. The key environmental factors influencing the distribution of P. canaliculata in Zhejiang Province were altitude, mean temperature of the wettest quarter, maximum temperature of the warmest month, mean temperature of the driest quarter, and precipitation of the driest quarter. The findings of this study can provide a theoretical basis for the monitoring, early warning, quarantine, and control of P. canaliculata in Zhejiang Province.
