Abstract

In the paper the possibility of using the Normalized Difference Vegetation Index (NDVI) for a comprehensive geo-ecological assessment of protected areas has been considered. NDVI indicates the state of protected areas’ vegetation. As a model area, the Baidarskiy Reserve, which is located in the south-west of the Crimean Рeninsula in the administrative borders of Sevastopol, has been investigated. The results of the NDVI calculation for the landscapes of the protected areas of the Sevastopol region in general and the Baidarskiy reserve are in particular have been given. There are 36 types of landscape have been noted for the Baidarskiy Reserve, and 56 have been presented in Sevastopol. The index is calculated using the QGIS software. It is determined that NDVI differs from 0.36 for residential complexes to 0.72 for oak and beech forests on medium slope.

The methodology for assessing the state of vegetation of protected areas using NDVI has been given. The contribution of NDVI to the geoecological situation has been estimated based on the deviation of the indicator from the mean value for each type of landscape. The results are translated into points. The area of landscapes with a normal state of vegetation was 67 %, critical and crisis 17 %. The rest of the territory (15 % of the area) is attributed to the conflict geoecological situation.

Based on the analysis of NDVI and the reserves of terrestrial phytomass, the areas of deteriorated vegetation for the model zakaznik have been determined. They are located on agricultural lands, burns and sparse forests. The leading ecological role of the vegetation of the Baidarskiy Reserve for the geoecological situation in the Sevastopol city has been proved.
