Опыт применения ГИС-технологий для оценки масштабов воздействия горнопромышленного комплекса на природные системы юго-востока Забайкалья

Abstract

The article discusses the methodology of using the GIS technology for assess the extent of the mining complex (GIC) impact on natural systems on the example of South-Eastern Transbaikalie. The isolated objects of GIC, the disruptive effect of which on the landscape is clearly visible at the satellite images, are marked in Google Earth software. To assess the impact of these facilities on natural systems it is proposed to allocate three zones: complete destruction of landscape, partial transformation and indirect influence, which reflect the degree and nature of the influence of GIC elements on the environment. Using the software Arc- GIS, ArcView and GlobalMapper building zones of the selected objects influence were allocated, the share of the South-East of Transbaikalie was estimated, which subjected to their influence, as well as the impact on existing specially protected and highly valuable nature areas. It was shown that more than 60 % territory of the South-East of Transbaikalie is now more or less influenced by GIC
