Amostragem sistemática versus amostragem aleatória em floresta tropical úmida de terra firme na região de Manaus

Abstract

An evaluation was made of the efficiency of systematic sampling in comparison with random sampling, both applied in forest inventory. The representative forest inventory, testing both applied in forest inventory. The representative forest inventory, testing both sampling methods, was carried out at th Forest Management Basin (bacia 3). Each method sampled 12.5 per cent of the 96 hectare forest area.The efficiency was evaluated by calculating the standard error in each case. The systematic sampling has been shown to be more efficient than the random sampling in the Bacia 3.
