Abstract:
Objective To predict the current and future ecological suitability distribution areas of Scutellariae Radix in Shandong Province at present and in the future;To screen the main environmental factors affecting its suitable distribution;To provide a reference for the protection of wild resources and the site selection artificial planting of Scutellariae Radix.Methods Taking Scutellariae Radix as the research object,based on the MaxEnt model,the potential suitable habitats were predicted using 84 distribution points of and 48 environmental factors of Scutellariae Radix,and the main environmental factors affecting the distribution of Scutellariae Radix were explored.Its potential suitable habitat areas were predicted under four greenhouse gas emission concentration scenarios(SSP126,SSP245,SSP370,and SSP585)for the years 2021-2040,2041-2060,2061-2080 and 2081-2100.Results The MaxEnt model was optimized through feature combination and regularization constant parameters,and its predictive ability was good(AUC value of 0.871).The primary driving environmental factors affecting its distribution were the maximum temperature in the warmest month(bio_05),soil gravel content(cf05)and altitude(elev).Under the current climate conditions,Scutellariae Radix is mainly distributed in the hilly areas of central and southern Shandong and some areas of in the hilly areas of Jiaodong.Under the future climate conditions of SSP126,SSP245,SSP370 and SSP585,the areas of suitable habitat of Scutellariae Radix in Shandong will show a decreasing trend.Except for the SSP126,the medium and high adaptation areas of Scutellariae Radix will disappear in the other three modes.Conclusion The results of this study can provide an important reference for the protection,rational utilization and planting layout of Scutellariae Radix in Shandong Province.
