Comparative character and monitoring of some parameters of the soil and vegetation by remote sensing in the zone of Zangilan
Main Article Content
Abstract
It is important to reveal a character, scale and development line of the change in order to determine a potential and future enlargement direction of ecosystem. The monitoring of the changes occurring in some parameters of soil and vegetation in the research zone by GIS has been performed and the consequences have been compared in the article. It was determined that the positive tendency was shown in some parameters of soil and vegetation, but negative tendency was shown in some parameters. An investigation of the changes by the remote sensing were given on the basis of different parameters (NDVI, LST, VHI) using the satellite images (Landsat 5 TM; Landsat 8 OLI) in the research zone. Change of the area of forest ecosystem under the negative and anthropogenic influences were compared on different years (1990-2022 years). It was determined that an area of the optimally developed forests decreased 84.5 % (10.838.05 h). At present the serious degradation has occurred in a negative direction of the available forest area. The Sentinel-2 satellite images have been used to evaluate changes occurring in soil use/ soil cover (LU/LC) in the active war phase (2016-2022 years). The soils of the plain and foothill regions in the district have been subjected to all the types of degradation (physical, chemical, biological) as a result of the military-technogenic effect.
