Regional evaluation of ecosystem diversity of the Northeastern Transbaikalia orobiome

Abstract

The evaluation of the ecosystem diversity of the Northeastern Transbaikalia orobiome has been completedon the basis of conjunctive analysis of floristic and geobotanical components of its vegetation cover. For the first time, acomplex method to evaluate ecological and geographical patterns in the differentiation of species (vascular plants) andphytocoenotic (vegetation communities) diversity has been used on the basis of the biome concept. It has been determinedaltitudinal gradients and regional specific in typological diversity of altitudinal spectra of vegetation and individual belts.The geographical features of ecosystem diversity development and its factors have been revealed at a regional level usingliterature, collection and cartographic data.
