Abstract
Forest shelter belts are one of the effective approaches in the fight against wind erosion, improving the microclimate of fields, protecting roads and reservoirs. The problem of assessing forest plantations and prospects for their creation is relevant for many countries of the world, due to the problem of desertification, water and wind erosion, as well as the global food crisis. The carried out analysis of scientific literature has shown that the existing assessments of forest shelter belts with insufficient degree are being taken into account the modern methods of remote sensing.Therefore, the problem of assessing forest shelterbelts from satellite imagery is relevant.The main part and research results. During the summer period of 2019, in the territory of the protective forest plantations of Fergana Valley of the Republic of Uzbekistan there were laid 170 testing plots. Then 20 test sites, which were used as reference for thematic mapping, there were laid with the collection of additional information: location coordinates and bookmark location.The purpose of the study is to assess the area of forest shelter belts zones of the Republic of Uzbekistan using remote sensing.The object of the study is forest shelter belts of Fergana Valley of the Republic of Uzbekistan.
Highlights
Forest shelterbelts and desert fodder plants are one of the effective approaches in the fight against with wind erosion for livestock feed, improving the microclimate of fields, protecting roads and reservoirs.The problem of assessing protective forest stands and perspectives of their creation is relevant for many countries of the world, due to the problem of desertification, water and wind erosion, as well as the global food crisis.The carried out analysis of scientific literature has shown [1,2,3,4,5] that existing assessments of forest shelterbelts and desert fodders are not sufficiently taken into account the modern methods of distance sensing
The climate of Central Asia, including Uzbekistan is determined by the situation in this region, the territory of which is located at a considerable distance from the main sources of moisture - oceans
The author’s research results, which are aimed at filling the gaps in the study of monitoring and evaluation of protective forest belts of the Republic of Uzbekistan according to remote sensing data
Summary
Forest shelterbelts and desert fodder plants are one of the effective approaches in the fight against with wind erosion for livestock feed, improving the microclimate of fields, protecting roads and reservoirs. The surface of the soil heats up to + 70 °, sand up to + 90 ° (167) Such high air temperatures in combination with low humidity and winds cause the occurrence of dry wind phenomena. The local ones include strong dry winds that occur in the southeastern part of Central Asia, carrying a huge amount of sand and dust, called Afghans These are westerly winds, reaching 17–20 m / s and lasting up to 5 days. Dry and hot winds are widespread in Central Asia, blowing on the mountain slopes and in the foothill plains of the southern mountain systems- Garmsili are usually of the eastern and southeastern directions, developing speeds of up to 10-15 m / s and more. Years of research and production experience show that these obstacles can be greatly reduced by creating systems of protective forest plantations in the agricultural territory, improving its aesthetic appearance.[13,14,15,16]
