METHOD comprehensive assessment of forest ecosystems in the technogenic impact AREAS OF INDUSTRIAL FACILITIES

摘要

FIELD: agriculture.;SUBSTANCE: method includes selecting venues of studies that meet the requirements of representativeness, placing stationary test areas and subsequent carrying out different kinds of biological monitoring of plant communities and soil covering of ecosystems at a different distance from industrial facilities. In the process of monitoring of plant communities the following is consistently performed: isolation of boundaries of stationary test areas; mapping the trees with making of a detailed plan of location of trees and shrubs; an assessment of biodiversity of tree canopy, undergrowth, underwood; determining the productivity of planting; an assessment of sanitary and medical condition of individual trees and forest stands; an assessment of qualitative condition and prospects of development of the undergrowth; analysis of dynamics of forest resources and determining the direction of successional processes in forest plantations; dendrochronological analysis of growth of the main forest-forming species; lichen-indication; geo-botanical studies of the living soil mantle; palynological studies; cytogenetic studies; morphogenetic studies of plants. In the process of monitoring of soil mantle the following is consistently performed: the breakdown of the territory for the network of squares, and the implementation of heeling in the corners of the squares with their additional drilling; soil sampling of soil humus-accumulative genetic horizon and morphological description of the supporting soil profiles; carrying out of soil-chemical laboratory analyses and carrying out cameral treatment of field data with the subsequent construction of agricultural cartograms based on their results; leveling surface survey and creation of models of relief of the territories under study.;EFFECT: method enables to implement a comprehensive collection and analysis of field data on the stationary test areas for assessment of condition of forest ecosystems and the impact on them of anthropogenic factors in the dynamics, and does not require significant financial costs of expensive equipment.;10 dwg, 6 tbl, 1 ex
