Analysis of the Influence of Temperature and Precipitation on the Beginning of Wood Removal in the Summer

Abstract

The purpose of logging roads is an effective carting out of the planned amount of harvested wood. Main problems: the problem of increasing transport accessibility of forest resources; the need to take into account and neutralize the negative impact of factors that affect the carting out of harvested wood; minimize costs across the entire supply chain. All these problems are affected by natural and climatic factors. Based on the analysis of the practical experience of logging companies, the amount of moisture in the ground has a large influence on the start of operation of summer roads. It was found that at the beginning of the summer logging road operation season, in addition to the water and heat regime (precipitation and their amount), the amount of moisture in the soil is also affected by the moisture of meltwater. Retention of meltwater in the soil depends on the freezing of the soil in the autumn-winter period, as a result, the most freezing of soils occurs when there is an excess amount of water in the soil. Research in this area is topical, since the amount of precipitation before constantly falling snow in the autumn period has an impact on the process of retention of meltwater in the ground and has a significant influence on the beginning of timber carting out in the summer. As a result, the purpose of the research is to analyze the influence of precipitation in the spring period, positive air temperature and amount of water in the soil in the autumn period on the beginning of timber carting out along summer roads, as well as to compile a corresponding regression model. The object of this research is data on the dates of the beginning of timber carting out in the summer from the logging territories of enterprises in the Krasnoyarsky kray
