Spatial Distribution Patterns of Vegetation Cover in Deserts of Central Kyzylkum with Application of Vegetation Indices (VIs)

抄録

The main goal of this article is to understand the trends of spatial- temporal changes of vegetation cover in relation to soil salinity under different land use patterns in Central Kyzylkum of Uzbekistan. For mapping the spatial distribution of plant communities, two main factors (soil salinity and vegetation classification) were recorded for assessing transect-ecological zones (TEZ) of vegetation cover in Central Kyzylkum. For assessing the ongoing processes of degradation of vegetation cover and its changes, we selected satellite images (Landsat TM, ETM+) for beginning of seasonality within the early period of April, 1987 and May, 2010; and seasonal variation of vegetation (greenness) in various plant communities was monitored at ecological scales within the TEZ. Computerized regression for spring seasons with environmental driving factors influencing plant biomass for different plant communities including dominate species of Artemisia and Salsola; which is appropriate for phytoindicators were modified and designed for different ecological scales of desert zones in Central Kyzylkum.
