摘　　要：本文采用整株挖掘、分割称重法野外获得15株赤松和16株侧柏的单木及器官生物量实测数据,结合野外取样和室内含碳率测定求算出树木各器官及整株含碳量。以含碳量为因变量,树木胸径和树高为自变量建立含碳量回归方程。结果表明:以胸径为自变量的一元含碳量方程与以胸径、树高同时为自变量的二元含碳量方程均达到极显著水平。该方法与传统的方法相比,具有省时、省力、针对性强的特点,因此,所建方程不仅可用于两树种的碳储量计测研究,同时也为今后其他树种的碳储量计测提供了可供借鉴的技术方法。To get the carbon content of tissues and whole trees from Pinns densiflora and Platv cladus 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 independent variable and the binary carbon content equation with DBH and height as the independent variables. This method saved time, labor and had a specific target compared with traditional methods. Therefore, the equations not only could be used to measure the carbon storage of the two species, but also provide technology way to measure other species for reference.
