Remote sensing based pasture qualification in the Kyrgyz Republic

    

         Kyrgyz Republic is a mountainous republic and the main direction of agricultural is livestock, which is based on feed from natural pastures. Pastures of Republic cover approximately 9.2 million hectares or almost 86% of all agricultural land.
The main direction of livestock breeding in Kyrgyzstan is sheep breeding. In recent years, Kyrgyzstan has seen an increase in the number of livestock. 
           As a result of intensive economic use, the biological diversity of vegetation and its productivity decreased.
There is a need for systematic observation of the state of grazing land, obtaining timely information about the direction and scale of changes occurring place in them.
         At the modern technical level the problem of getting information about the state of natural forage lands is solved with the use of remote sensing, allows to get enough volume of information about the state of pastures.
Satellite images have significant visibility and informativeness, allow an objective assessment of the situation and take effective measures for the conservation of natural fodder land and their rational use.
         Research is aimed at assessing the state of the vegetation cover of the pastures of the Barskoon aiyl aymak (county) according to satellite images, depending on the weather conditions.
The analysis of the vegetation index NDVI and SAVI during the growing seasons from Landsat imagery for the period 1991 to 2015 was carried out. The correlation of vegetation between the field geo-botanical survey (geobotanical map) and the satellite image Landsat TM Surface Reflectance 4-5 TM  for 1991 was investigated.
