MONITORING THE INFLUENCES OF NATURAL FACTORS TO VEGETATION DEVELOPMENT BY OBJECT BASED IMAGE ANALYSIS (OBIA) OF THE MODERATE-RESOLUTION IMAGING SPECTRORADIOMETER (MODIS) NORMALIZED DIFFERENCE OF VEGETATION INDEX (NDVI) IMAGES

Within this article, we will discuss the natural and anthropogenic effects on vegetation and its degree in Syrdarya p rovince. By searching the abovementioned issues, we have created a statistic model of integrated meteo - and hydro - and RS data. Throughout this model, we have analyzed the correlation share of various natural factors in vegetation period. MODIS NDVI images have been used, which differ from other RS data with images free of charge, also with the vegetation development information in. In accordance with results of these analyses, in Syrdarya province the vegetation development demands the air temperature, ind eed, it is natural phenomenon, because the vegetation period occurs in hot term of the year. Unfortunately, in this period, the water amount decreases and vegetation withers and dies in the result of water shortage, besides, that land becomes saline. In an alysis of vegetation period, RS images play im- portant role. In this article, we will review the possibilities of RS and OBIA images in statistical analyses.
