PRODUCTIVITY OF TUVA LANDSCAPES

Abstract

The results of long-term studies of biological productivity of natural and anthropogenic agricultural landscapes of the Republic of Tuva are presented. Phytomass reserves and vegetation products are considered as an important integral characteristic of the state of landscapes and an informative indicator of the effectiveness of optimal solutions in managing ecosystem dynamics – grass ecosystems, agrocenoses, forest fragments. It was revealed that forests form 95% of the phytomass, but only 46% of the production; grass ecosystems with an area of 20% create 48% of the production. It is shown that due to a short period of development of the region’s territory and a slight transformation of the environment, most landscapes retain their productive potential. In the context of the traditionally livestock-based development of the region’s economy, there is a significant reserve for optimizing the functioning of agricultural land, determined by the natural diversity of landscapes and the correct choice of farming priorities. The purpose of the study is to assess the reserves of phytomass and pure primary products of various landscapes of Tuva. The main objectives of the study are to assess the contribution of landscapes to the biopotential of the region, depending on the terrain, the combination of bioclimatic conditions and the uniqueness of the soil and vegetation cover.
