Influence of technogenic and climatic factors on the condition of forest stand in the sanitary and protective area of OOO “Tomskneftekhim”

Abstract

The influence of natural and man-made factors on the development and ecological state of forest plantations in the sanitary protection zone near the large industrial enterprise OOO “Tomskneftekhim” has been studied. Plantings in "Sandy Lake” specially protected natural area of regional significance served as control ones. The influence of industrial production on growth and development of trees has been determined, as a result of which it has been revealed that the growth rate of Scots pine in control plantings is significantly higher than in areas subject to the influence of industrial factors. The study of the influence of climatic factors on the growth and development of forests has showed that there is a correlation relationship between the signs in the sanitary protection zone: the temperature regime has influenced the increase in biomass. In years with a high average temperature, the average annual growth of Scots pine decreases in comparison with years with a more moderate temperature regime. The influence of precipitation on the average annual radial increment of Scots pine has been analyzed, no dependence has identified. The construction of a two-factor model of the dependence of growth and state of tree stands of the SPZ of OOO “Tomskneftekhim”, taking into account the location and average annual temperature has become the result of the study. The constructed model has shown that the forests of the sanitary protection zone can remain resistant to negative environmental factors for a long time. However, the trend of an average annual radial growth of Scots pine has been showing a gradual decrease in this indicator since 1990 as a result of an increase in man-made loads. Therefore, in order to preserve the plantings of the SPZ, it is necessary to carry out a number of restoration measures that will increase their resistance to external man-made factors and adverse climatic conditions.
