List of publications of the laboratory researchers

The basic directions on research activity of the laboratory are:

• Research of dynamics of cycles of the Biogenic and dissipated elements in a process of the autogenic, digressive (caused by air industrial contamination, fires, forest fellings) and restoration forests succession

• Research of dependence of the soil- and forest generic processes under various conditions of the forming of them (relief form, descriptions of laying breeds and loose deposits, anthropogenic influence)

• Development of methods of biogeochemical monitoring of boreal forests

• Development of the approaches to recovery of the forests, liable to air industrial contamination.

• Exposure of mechanisms of transformation of the boreal forests in terms of the aerotechnogenic contamination by means of estimation and analysis of change of the composition and structural parameters of vegetable associations, properties of soils and their animal population

• Development of technology of the monitoring of anthropogenic influences, combining application of traditional methods of collection and the analysis of the field information, forest taxation’s information, and also the newest methods of using and treatment of the controlled from distance information

The basic academic results

• It is shown, that in a process of the autogenic succession of the northtaigas forests, in the soils there is a substantial accumulation of accessible for living organisms of combination of elements of feed, and narrowing of the C/N relation

• On the basis of parameters of biogeochemical cycles, primary productivity and specific composition of the vegetable associations, there exposed of the basic stages of technogenic digression of the northtaigas forests.

• It is shown, that technogenic digressions in the fir-groves of the greenmoss and pine forests of the greenmoss - lichen, are characterised by the general features: the stages of meadow-suffruticous forest and sparse growth of trees are identified, there is decline in vegetable associations amounts of species due to the fall of mossy, lichen and herbages, and participation of wavy hair grass and black crowberry increases.

• It is discovered, that in a process of the pyrogenic-technogenic digression of the northtaigas forests there is substantial impoverishment of soils and plants by the elements of feed: along with the deficit of nitrogen discovered the phenomena of deficit of magnesium and calcium.

• It is shown that the forest ecosystems formed in transit terms and the lower parts of slopes, differ by a considerable capacity of rotation, that explains the high level of their stability to the air industrial contamination.

• It is shown that the forest ecosystems, formed on the rich with the grounds soil generic breeds, differ by a high level of the stability to the air industrial contamination by the acid generic matters, and combinations of the heavy metals.

• The method of the estimation of typological and taxonomic variety of forests in the conditions of the industrial contamination, with the use of information of the field experiment, the controlled from distance sounding, and quantitative methods of joint treatment of this information, is approved

• Approaches to renewal of forests in the conditions of the air industrial contamination, are developed.
