Effects of Precipitation, Land Use Hitory, Soil Properrties and Plant Species Richness on EVI in Drought Condition

Abstract

Drought is phenomena of below-normal precipitation and affecting people and nature environment. It was suggested from previous studies that plant species diversity enhances community vulnerability for drought. Extreme climatic event affect community assembly and evolution. Legacies of land use activities continue to influence ecosystem structure and function for decades or centuries or even longer after those activities ceased. These factors, however, did not consider with evaluation of drought effect in global scale studies.We evaluated the effect of annual precipitation in drought, pre-drought and post-drought year, plant species richness, land-use hiatory and soil type on EVI in drought, pre-drought and post-dtought year.
