Радиальный прирост дуба черешчатого в условиях Липецкого промышленного центра

Abstract

The features of the radial growth of an oak tree in the conditions of the Lipetsk industrial center are studied. The main source of environmental pollution in the Lipetsk region is the smelter «Novolipetsk Steel», which accounts for 86,2 % of all emissions to the atmosphere from stationary sources in the region. It is established that in the industrial pollution conditions there is no significant reduction in the radial growth of oak. In the industrial pollution conditions a positive correlation of the radial growth values with temperature in August (P = 0,3242) and a negative correlation with temperature in October (P = -0,2251) and precipitation in April (P = -0,2542) was noted, under control conditions a negative correlation with temperature in November (P = -0,3949) and precipitation in September (P = -0,2896) was marked. Thus, oak is a sustainable wood species to the pollution influence within the Lipetsk industrial center. This fact makes it possible to predict the success of this tree species with its sanitary-protective functions in relation to industrial pollution.
