Study of forest strip systems agrolandscapes structure

Abstract

The aim of the scientific work is to investigate the forest bands system structure of agrolandscapes with the aim of establishing the duration of periods of its development for determining the main forest species. Research Methodology: complete counting of trees on temporary test plots laid in typical forest belts, analysis of main tree trunks and obtaining equations of relationships between heights and ages; modeling the development of the structure of forest belts using these equations and formulas for determining the distance between forest belts. It was found out that forest lane systems in their development consistently go through certain periods: unsteady, stationary, post-stationary and decaying functioning. The main criterion for choosing the main species when creating forest belt systems is the longest duration of the stationary and post-stationary functioning of the system. For forest strips created from Quercus robur, this duration is 81 years, Fraxinus lanceolata - 63 years; Robinia pseudoacacia - 55 years. According to this criterion, it is not advisable to create forest strips from such main species as Populus nigra and Ulmus pumila on southern chernozems.
