5 CONCLUSION
Based on the actual distribution data of PWD and current (1950–2000)
and future (2050 and 2070) climate data, the MaxEnt model was used to
predict the potential distribution area of PWD in China. The prediction
results showed that, under current climate and environmental conditions,
moderately and highly suitable habitats are mainly distributed in Anhui,
Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Sichuan, and other places. In
2050 and 2070, the area of total suitable habitat and highly suitable
habitat will expand significantly
and spread to the Northeast. The main climatic factors affecting the
potential geographical distribution of PWD are temperature (max
temperature of the warmest month (bio5), mean temperature of the driest
quarter (bio9), rainfall (coefficient of the variation of precipitation
seasonality (bio14), and precipitation of the wettest quarter (bio16).
By predicting PWD’s potential geographical distribution, a basis for
quarantine, supervision, and timely prevention and control can be
obtained.
