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

DYNAMICS OF MOUNTAIN FOREST IN RESERVE AREA (“STOLBY” RESERVATION)
DescriptionAccounting stands (1959, 1977, 2007) revealed reduction of areas dominated by deciduous species and larch in the State Nature Reserve "Stolby". Area stands of fir and pine increased. Area stands of cedar and spruce didn’t change over the last 50 years. Deciduous stands differs rapid accumulation of stock, but they have productivity lower then conifers. There is a shift in even-aged stands to multiple-aged stands in coniferous formations. They are close to a climax state. Cedars grow on the type of the even-aged stands, because they appeared in the area recently

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

ANALYSIS OF TREE HIGHT GROWTH CURVE DEVIATION OF SCOTS PINE IN MINUSINSK PINE WOODS
DescriptionA deviation from tree height growth trends of Scots pine is analyzed. They have a periodicity and vary both by the amplitude and period. At average the value of period is 40-50 years and has a significant variabil-ity. It depends on longevity of tree life and age classes. The deviation depends on relation between the trees in stand. An abiotic factors effect increases and comes to the fore under constant of actual adverse environment conditions for growing

AGE-SPECIFIC STRUCTURE OF FOREST STANDS OF TAIGA ZONE OF THE WESTERN SIBERIA
06.00.00 Agricultural sciences
DescriptionAnalysis and research of age-specific structure of different forest stands of the taiga zone of the western part of Siberia are presented in the article. It was determined that it is very difficult to meet trees of the same year even in simple single- stage clean clear-coniferous forest stands, it is necessary to take into account the age-specific stage of a xyloid plant under transition to the level of a growing tree as well.

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.

DescriptionOn the basis of the data gathered from various districts of Medial Siberia it is mounted, that at trees of the Siberian fir (Abies sibirica) for associations d1.3 =f (dп) and dп =f (d1.3) a build-up of the uniform normative (even at level of a wood band) leads to the significant magnitude of errors, but can be used at study of blanket regularities
