Quantitative assessment of competition of the forest stands of scots pine pinus sylvestris і. and its impact on the growth of ling (calluna vulgaris (і.) Hull.)
Based on the “micro ecosystem” approach (Sannikov, Sannikov, 1985) mathematical and statistical analysis of conjugated chorologic changes in the structure and function of coenopopulations of ling depending on changes in the structure and function of the determinant of community — of the forest stand edificator Pinus sylvestris was conducted. Study and quantitative assessment these relations were carried out in 35-year-old pine stand cowberry-bilberry middle taiga subzone of West Siberia. It was showed a reliable negative dependence of abundance, phytomass and growth of Calluna vulgaris undergrowth from partial indices of root and light competition of forest stand. More significant negative correlation between the parameters of ling was obtained from proposed by us the integral index of root and light competition of forest stands.
