Biological productivity of the landscapes of the Republic of Tyva

Abstract

The article considers the results of research on the biological productivity of the ecosystems of the Republic of Tuva, in particular, the dynamics of phytomass reserves, pure primary products were carried out in various landscapes of Tuva from 1996 to 2021. It was revealed that the landscape zones of Tuva differ in area, climate and biome structure, where the main producers are grass ecosystems that form 48% of the NPP, the contribution of forests reaches 46%, agrocenoses 1.5%, i.e. more than 90% of products are created in almost equal quantities by forest and grass biomes.
