Ecological status and postagrogenic transformation of landscapes (a case study of the Republic of Buryatia)

Abstract

For the first time, the Buryatia Republic has been given a comprehensive environmental and economic assessment of post-agricultural landscapes and the desirability of returning them to agricultural circulation. Detailed geobotanical descriptions are carried out and the structural-dynamic organization features of plant communities are established, the stages of restoration succession are analyzed. Agrochemical and agrophysical studies of the soils of deposits were carried out. The characteristic is given to the features of overgrowing of post-agrarian landscapes with trees and shrubs and the state of protective forest belts. For the first time for the Buryatia Republic, the place of fallow lands in the landscape hierarchy has been identified. An original map «Use of the lands of South-Western Transbaikalia», reflecting the territorial differentiation of fallow lands, was compiled. For one of the key areas of the study, an original map was compiled «Anthropogenic and spontaneous (natural) transformations of the geosystems of the Tunkinsky depression». For the first time, an economic model has been created for the Buryatia Republic for the contribution of individual agricultural sectors to gross domestic product. The model reflects the significance of each type of product and the appropriateness of its production on post-agricultural landscapes if they return to agricultural circulation. Sociological studies of business entities on the subject of their readiness to enter into agricultural circulation and reclaim fallow lands were carried out.
