The features of landscape mapping in the environmental assessment

Abstract

Along with the General scientific methodology of mapping of geosystems, special cartographic models are developed for practical purposes, which take into account the needs of the industry for which they are created. The article deals with the main methods of mapping to solve the problems of environmental impact assessment of objects Verkhnechonskoye oil and gas condensate field and the system of external transport of oil. Due to the specifics of the Northern territory in the legend of the map reflects the geological and permafrost characteristics of each landscape, as well as the main processes taking place in them. Analysis of the set of factors displayed for each landscape made it possible to divide the latter into three degrees of stability (the ability to restore its original appearance after external influence). For convenience of perception of the cartographic image, each area is shown in the color scale with separate numbering of contours. Colors within each district differentiate according to certain basic typology landscape on different landforms, which alter hydroclimatic conditions. The article gives examples of legend maps and explanations to assess the transformation of landscapes in natural and anthropogenic conditions. The modern transformation of landscapes and the forecast of their changes are based on a detailed assessment of natural conditions, their dynamic and evolutionary transformations, ecology of plant species, and the nature of anthropogenic impact.
