Using morphophysiological assessment of pine stands in determining the sustainability of forest ecosystems

Article preview

A complex of field, laboratory and theoretical studies was conducted, including selection, laying and silvicultural-taxation and soil survey of sample areas, regular collection and physiological and biochemical analyses of pine needles samples, measurement of electrophysiological characteristics of trunk tissues, mathematical and statistical analysis of data and spatial modeling with GIS. Based on the data obtained, the state of the stands was studied. The results of the research allow us to objectively classify the trees in the studied sample areas according to the degree of stability to three successively changing states: normal, transitional and critical.

Complex influence of mountainous terrain and air-industrial pollution on biometric characteristics of pine plantations

Article preview

Geomorphology of the territory is one of the main factors influencing the formation of atmochemical pollution halos of forest ecosystem areas. As a result of the conducted research, spatial regularities of distribution of stand parameters depending on the terrain characteristics were quantitatively established. It was revealed that the increase in elevation, distance to the sources of pollutant emissions into the atmosphere and decrease in illumination of the macro-slope is accompanied by a decrease in the average diameter and height of stands. The differentiation of the degree of influence of natural and anthropogenic factors is adequately assessed by the equation of dependence of basic forest taxation characteristics of plantations on the parameters of forest site location.
