Description
This article speaks about the impact on the soil by the logging machines is the compaction, deformation, mineralization of the soil, changing its structure, biological, water-physical and chemical properties. The negative impact of machinery on soils depends on the construction and systems of machines, technologies of timber harvesting, climate, forest, and other factors. This work considers a comprehensive assessment of the impact of the process of logging on the environment and proposes measures to reduce the anthropogenic impact on soil, water bodies. We have determined the annual volume of emissions to the atmosphere from combustion engines of logging equipment, characteristics of gross emissions of pollutants into the atmosphere after cleaning of the neutralizer gas; we have also determined the amount of pollutants by vehicles in the transportation of wood total in the process of clear cutting

Description
On the basis of the analysis of morphological indicators of wood cultures of a linden it was recommended to start caring cuts of cultures (the combined method) with removal from low ranks of trees in diameter at height of a breast to 8 sm and from high ranks of 4 trees (24 sm). Intensity of cuts - 35 % from the general number of trunks and 15 % on weight

STRUCTURE OF MIXED FIR PLANTINGS BY DIAMETER, AREA OF THE SECTIONS AND AREA OF THE GROWING
06.00.00 Agricultural sciences
DescriptionQuestions of examination of the structure of the mixed plantings by three factors: diameter of stems on height bosom, area of the cross-section and area of the growing are considered in this article. It is determined that all rows of the distribution have expressed right-side location variant, which is possible to explain as age and spatial spottiness of the fir plantings

CONSTRUCTION OF BIOGROUPS OF LIGHT-CONIFEROUS AND DARK-CONIFEROUS PLANTATIONS OF TAIGA ZONE
06.00.00 Agricultural sciences
DescriptionThe author offers under studying of plantation structure to underline intermediate units between stands and growing trees under the name “ social groups”. In the result of made researches there were received some conclusions. Distributions of distances in biogroups (social groups) in great cases (50% and more) adequately are described by normal and logarithmic function. Use of statistic indexes to describe small fetches was substantiated.

06.00.00 Agricultural sciences
DescriptionModels of model trees in the manner of equations for calculation of the current increase of trees at radius in cedar, mixed fir and pine plantings are received. At calculation of the current increase at radius and height using the diameter of a tree on height bosom without cortex, age tree and average distance from nearest tree on radius is recommended.

01.00.00 Physical-mathematical sciences
DescriptionThe aim of work is to get prognostic equations, taking into account the natural growth of pine forest stands of Krasnoyarsk forest-steppe along with influence of forestry arrangements and elemental factors. Dependences of weight average diameter and mean square deviation from age and plantation density were received in the article.

PREPARATION OF LUMPY VEGETABLE WASTE IN PRODUCTION OF MODIFIED BUILDING MATERIAL
DescriptionRational and efficient use of natural resources is an important element of sustainable development. Waste is a significant loss of material and energy resources. Recycling and disposal of waste can be a cause of pollution, harmful substances and infections on people. Index of waste production is closely linked to the level of economic activity in the country and sums up the structures of production and consumption that are formed in the society. Reduction of capacity size of waste production is a measure of promotion of the economy sector to less material-intensive structures of production and consumption. Phytogenic wastes are mostly formed in the timber industry, and also are pollutant source of environment. Continuing production and accumulation of waste is a serious environmental problem. The main reason for these circumstances involves insufficiency of power in added-value wood processing, that increase the problem of integrated utilization of low-grade wood, small wood and demolition wood. As a result, the main competitive products in the timber complex of the Krasnoyarsk Territory are industrial wood and roundwood. Solution to these topical issues of optimum use of the resulting waste in the Krasnoyarsk Territory needs to be solved with the help of mathematical modeling of process optimization of recycling lumpy plant waste. Rational use of lump plant waste is one of the most serious and, unfortunately, unresolved problem
