Comparative characteristics of the productivity of above-ground phytomass of the vegetation cover of the «Altyn-Emel» SNNP

Abstract

Biological diversity monitoring, phytomass vegetation cover productivity in nature, and the revealing of  the factors affecting  them are of paramount  scientific importance. The given paper discusses the characteristics of the ground phytomass productivity of the vegetation covers in “Altyn-Emel” National Park based on the results of the studies carried out in June and September 2019.

The given study was aimed at determining the productivity of the vegetation covers in “Altyn-Emel” National Park. The traditional methods of field geobotanical investigations were used to evaluate the productivity of vegetation cover ground phytomass. The monitoring and evaluation of the current state of the ground phytomass of the  vegetation cover play a key role in theory and practice. The results of the study carried out in June 2019 showed that the highest phytomass productivity indicator was observed in the tamarisk-grass-forb community, and the lowest one was in the Saksaul-wormwood-keireuk community. The highest productivity was also found in the shrub-wormwood community, and the lowest productivity  was present in the Saksaul community. According to the results, the phytomass productivity of the vegetation cover depends on several factors. They are desertification and an intense process of anthropogenic activity that reduce the floristic composition of the regional plants and cause wind erosion. Beside these factors, climatic and meteorological phenomena also affect.  Taking into account all these factors, the authors recommend continuous monitoring of vegetation cover in "Altyn-Emel" National Park.
