Optimizing the distribution pattern of species under climate change: the protection and management of Phellodendron amurense in China

Objective Phellodendron amurense , a special species in Northeast Asia, is the source of wild medicinal Phellodendri Amurensis Cortex, second-level key protection China. Because its dual value medicine and timber, it has been cut large quantities, resulting sharp decline resources. It listed as national first-class rare tree species. Here, we aim to plan area tending for Chinese P. context climate change. Method In this study, based on Biomod2 model, main environmental factors affecting distribution potentially suitable areas current future were investigated. Furthermore, correlation between chemical components was determined by full subset regression. Habitat quality landscape pattern change InVEST Fragstats software land use data 1980, 2000, 2020. Then, Zonation used priority areas. Results The results showed that future, potential habitat will gradually move high latitude altitude northwest direction, suitability decrease sharply. Since deteriorated, fragmentation intensified. central part Greater Khingan Mountains forest Lesser be long-term stable sanctuary. Fengcheng City Tonghua County are most Conclusion existing nature reserve only contains 6.01% area, so propose expand cover larger proportion sanctuary implement management restoration plans increase connectivity. These can support action provide reference scientific basis further research, rational development, utilization .
