Abstract
Features of distribution of model East-Asian species Astragalus membranaceus , Gueldenstaedtia verna , Sсutellaria baicalensis , Sophora fl avescens have been studied. Prediction maps for each species under study have been composed. Modeling with using Maxent approach revealed that the spatial distribution of studied species is infl uenced by the complex of factors connected with mean parameters of temperature. Prediction maps for modeled climate change scenario showed the individual response for each species. Generally, obtained results didn’t reveal the potential decrease of East-Asian species distribution according to moderate climate scenario. Scenario with high increasing of atmospheric CO
2 concentrations showed the possible decreasing of plant distribution.
