Abstract
The article presents the results of correlation and regression analysis of the interrelationships of microclimatic indicators and the distance from the forest strip. Field studies were conducted in the dry-steppe zone of chestnut soils during 2020–2021 in the summer, autumn, and winter periods. The object of the study is a fortyyear old protective forest strip of openwork construction of the Kachalinskoye experimental-production farm of mixed breed composition of small-leaved elm (Ulmus parvifolia J.) and golden currant (Ribes aureum P.) along the edges of the strip. In the course of the analysis, various degrees of dependence of the studied factors on each other were revealed. Correlation analysis revealed a positive relationship (on the Cheddock scale) between the distance from the forest strip and wind speed (r = 0.94–0.96), humidity (r = 0.83–0.86), and air temperature (r = 0.80–0.89). The average and strong correlation between microclimatic indicators and the distance from the forest strip is noted in part of the measurements for soil humidity and temperature. The obtained regression models and determination coefficients indicate the proximity of the mathematical model to empirical observations.
