    Abstract The objective of this study was to analyze the relationships between total aboveground plant biomass versus altitude, latitude, longitude, mean annual temperature, mean annual precipitation, and species diversity. Simple linear regression analysis was used to study these relationships. Results showed that altitude was significantly, positively (R2= 0.038, P<0.01) related with total plant aboveground biomass. Meanwhile, when longitude (R2= 0.124, P<0.001) and latitude (R2= 0.221, P<0.001) increased, total aboveground biomass decreased. The relationship between biomass and mean annual precipitation was significantly, positively linear (R2= 0.149, P<0.001). Mean annual temperature was significantly, negatively correlated with biomass (R2= 0.145, P<0.001). The More >
