Abstract:
This study aims to establish the relationship between biomass and area and then to determine minimum sample area for biomass investigation by building suitable model. The investigation of the effect of area size on biomass was carried out in the period from July to August, 2012 in Caragana brushland of Semiarid Hilly Region of Loess Plateau, China. The size of sample areas changed from 1x1 m to 10x10 m and a series of samples were selected in the nested way. The canopy area, basal diameter and height of Caragana plants were investigated. Arrhenius model, Logarithmic function, Michaelis-Menton model and Logistic model were used to fit the biomass-area data respectively. The results showed that the aboveground biomass reduced sharply and then gently with the increasing sample areas, which was the best fitted with Logistic model. The minimum sample area was got when the second derivative of the best fitted biomass-area equation was 0.
