Study on the Boundary Optimization and Adjustment Scheme of Cangshan Nature Reserve
Biodiversity loss is a global hot issue,and nature reserves are considered to be one of the effective meas-ures to protect biodiversity.However,many protected areas nature reserves have problems such as protection gaps and overprotection.This study takes Cangshan Mountain of Dali as an example,based on different methods to ex-plore the protection benefits of Cangshan Nature reserve and boundary optimization adjustment plan.The integrated valuation of ecosystem services and trade-offs(InVEST)model was used to explore the quality of the three countries in the reserve.Biomod2 was used to simulate species distribution using 143 coordinates for 52 species combined with four broad categories of environmental data.Habitat quality and biodiversity in the study areas were assessed u-sing the habitat quality module of the InVEST model.Based on the species distribution model,it can be seen that the boundary of Cangshan Nature reserve in Dali basically covers the main distribution area of rare and endangered plants,while the division of the inner core area needs to be further adjusted.On the one hand,there is overprotection in the north of the core area;On the other hand,there is a large protection gap in the eastern core area,which needs to be expanded to ensure the effective protection of endangered plants in the region.
