Relative Sustainability of the Altai Transborder Ecosystems
Journal Title: Periódico Tchê Química - Year 2018, Vol 15, Issue 30
Abstract
Mountainous natural complexes of Altai cross-border territory is a unique object of studies into their durability against an external impact since they represent a complex mosaic structure. Authors used an integral characteristic as an assessment factor, which allowed to determine the durability of their soil cover. First, the river layer was converted into the scanning pattern. Next, all characteristics were translated into relative values, During the research, it was established that those ecosystems that formed on terrain consisting of steep slopes were more susceptible to adverse natural phenomena. It was discovered that the landscape is an optimal unit for determining the durability of ecosystems. The article provides results of an integral assessment of the degree of ecosystem’s ecological durability against an external impact.
