Methodology for integral assessment of environment state dynamics and its components in coastal-marine region of Western Yamal

Abstract

Recently, various monitoring programs have been operating on the territory of the permafrost zone, this is associated with both the development of the permafrost zone for various practical purposes, and with the growing interest of the scientific community in global environmental change trends (including the climatic changes). Under the influence of an anthropogenic factor or natural processes independent of humans, negative changes can occur in the territories occupied by permafrost, accompanied by environmental crises, natural or man-made disasters. To prevent such changes or take timely measures to protect and eliminate the consequences, it is necessary to understand the essence of the processes occurring in the permafrost zone, as well as develop plans for the balanced development of territories. The work is aimed at studying major natural phenomenon, i.e. the formation of specific geoecological conditions in the transition region from land to sea under climate change. The article discusses the proposed basic principles of the integral (point-rating) assessment of the dynamics of geoecological state of natural environment of the coastal-marine region of Western Yamal under climate change. The information basis of the proposed methodology for the integral assessment of the dynamics of the state of natural environment is the analysis of changes in the parameters/factors of natural and man-made environment, reflecting the composition, structure, and state of its individual components, and determining its geoecological state with climate change.
