Relação entre índice de área foliar, índice de vegetação EVI e dados climatológicos, na floresta nacional de Pacotuba-E. S.

Abstract

Leaf area index (LAI) is an important parameter of the vegetation canopy, and is used, for instance, to estimate evapotranspiration and productivity. The main objective of this work was analyzed the relationship between LAI and EVI and climatological data in three periods. The study area was at the National Forest (FLONA) of Pacotuba, south of Espírito Santo, Brazil. The vegetation indice used was EVI, product of sensor MODIS. The LAI was collected by LAI-2000 equipment. The data EVI collected inside each parcel of FLONA were affected for climatic factors as the Temperature and the Precipitation. It was verified that 56% of the variation of LAI can be explained by EVI. The vegetation indece EVI, product of sensor MODIS, confirms the relationship that there are between variations of climatic parameters and LAI.
