Simulation and analysis on marshes wetland plant diversity in Jilin Province under climate change
Jilin Province boasts an abundance of wetland resources,yet human misuse and climate change have led to a decrease in wetland areas and a decline in function.Investigating the impact of climate change on plant diversity in wetlands is crucial for the protection and restoration of these ecosystems.Currently,informa-tion and research on the future climate suitability of wetland plants are limited,and few studies have used stacked species distribution models(SSDMs)to investigate wetland plant diversity.Therefore,we used SSDMs to simulate the current distribution patterns of 30 dominant wetland plant species in Jilin Province,based on 6 601 sample points and 19 environmental factors.We identified the main factors driving the distribution of each spe-cies,and predicted changes under three future climate scenarios(SSP1-2.6,SSP3-7.0,and SSP5-8.5)in the fu-ture(2071-2100).Our results show that:the precipitation of the wettest quarter,soil pH,and max temperature of the warmest month are identified as crucial factors affecting the distribution of marsh wetland plant species.Species rich-ness in the eastern area is higher than that in the west,and it is unevenly distributed throughout Jilin Province,with the highest richness found in Dunhua City;under climate change,the distribution range and species richness of dominant marsh wetland plant species will decrease in Jilin Province;most of the dominant wetland plant species in Jilin Province have already protected,but the simulations show some suitable distribution areas and areas at high risk in the future that should be taken into account when building the conservation network.This study could provide a scientific basis for the conservation of wetlands in Jilin Province.
