Мониторинг процессов деградaции в пустынно-пастбищных земель с использованием гис технологий

The article presents the results of the analysis of the calculations of the normalized difference vegetation index (NDVI) for the desert-pasture territory of the Navoi region. In the course of the study, the long-term dynamics of the values of the vegetation index was analyzed based on the interpretation of satellite images from 2000 to 2020. It has been established that desert pastures are characterized by sparse vegetation in 2020 - a sharp degression of pasture plants is observed. At the same time, differences were revealed in the absolute average long-term maximum and average values of the index. In 2000, higher average long-term maximum values of the index are characteristic, the degree of vegetation is about - 80%, than in 2010 and 2020. The results of the study can be taken into account when analyzing the long-term dynamics of natural zonal landscapes, as well as for optimizing pasture loads during the growing season
