Abstract

Deterioration of the state of forests and illegal logging are a global problem of our time. The region of the Caucasian Mineral Waters has a small number of forest areas, so the need to introduce new methods for analyzing the state of forests is an important task in the conservation of forests in this area. One such method is geoinformational analysis. For the survey, the geoinformation systems ScanEx Image Processor 4.0, Mapinfo Professional 12, QGIS 2.8 have been used.

The species composition of the largest forest tracts of the Caucasian Mineral Waters is considered. The main reasons for changing the boundaries of forest areas have been determined. A geoinformational analysis of the changes in the boundaries of the forest tracts of the region has been carried out using remote sensing data for the period from 1987 to 2014. For the analysis, space images of the Landsat 5 and 8 system were used for the period from 1987 to 2014.

A classification of multi-temporal optical images has been made, which allowed obtaining the values of forest areas in different years and to calculate their percentage of forest cover. In 1987, the forest area of the region was 35.2 thousand hectares; in 1998, 41.99 thousand hectares, and by 2014 it was reduced to 33.16 thousand hectares.

On the basis of the data obtained, a series of maps characterizing the forests of the Caucasian Mineral Waters in different years has been constructed.

The conducted study led to the conclusion that the main changes in the forest boundaries occurred in the Mashuk, Lysoy, Zheleznaya, Beshtau, Verblud and Bik mountains. This is due primarily to the proximity to the most densely populated cities in the region: Pyatigorsk, Zheleznovodsk, Essentuki and the city of Mineralnye Vody.
