The method of ecologeomorphologic mapping of mountain areas based on the remote sensing data analysis

Abstract

The method of ecologeomorphological ratable mapping is suggested, the tectonically active mountain areas of different regions and landscapes taken as an example. The method is based on using of spectrozonal space images. Criteria and indexes of environmental deterioration according to natural factors are developed. Principles of middle-large scale mapping are worked out. For the first time ratable ecologeomorphological mapping was fulfilled for some mountain test sites: the Great Caucasus, the Northern Osetia, the northern part of Kuril Isis - in the moderate zone, Andes (Chile-Argentina) - in the subtropical zone, Sierra-Maestra (Cuba) - in the tropical zone. Method of space indication of dangerous slope processes is improved. Unlike other geomorphologic techniques this method allows to determine the boundaries of the dangerous processes with high precision and validity.
