The species diversity of medicinal plants as a whole and species diversity of plants used for curing of several classes of disease are considered. Statistical analysis of correlation between number of medicinal plants species in the regional biomes and climatic indices has been made. The sketch maps have been done and their analysis have been made. It can be assumed that number of medicinal plants in certain biome is correlated with the total number of species in that biome, meanwhile it is conditioned by geographical position that is linked with annual temperature and precipitation in the region. The closest connection is detected between the number of medicinal plants species and average annual temperatures. Comparatively close connection is detected between number of species and average annual precipitation. Analysis of correlations between medicinal plants number used for several classes of disease and climatic indices showed the analogous picture.
