To get the carbon content of tissues and whole trees from Pinus densiflora and Platycladus orientalis, this paper took the live data by way of excavating whole trees and weighing dividually in combination with sampling in the wild and determining carbon rate in door to construct the regression equations at diameters and heights as independent variables,carbon content as dependent variables. The results showed there were significant difference in the single-variable carbon content equation with DBH as the in...
