Abstract

Use of satelite images is known as a new technique to study changes in vegtation cover. On the other hand, RAINFALL plays a key role on the condition of vegetation cover. This article investigates the changes in vegetation and its relation to RAINFALL days and monthly time intervals over the (1995-1997) period. The region of study is part of Kol river basin located in an area surrounded by Hormozgan. Kerman and Fars provinces using geo-statistical methods. RAINFALL maps were generated based on the raingauges in the data collected by area. Maps of daily Normalized Difference Vegetation Index (NDVI) were transformed days images using into day composite technique. Bymaximum preparing a layer representing terrain-mapping units (TMU) the correlation between vegetation cover and RAINFALL was investigated in different land units. The results demonstrate varying degree of correlation. Specifically the correlation in alluvial and flood plains was strongest. Meanwhile The correlation in monthly time days interval was better compared to interval. The multi-variable regression was also determined as the most suited correlation relationship.
