【摘要】 本文采用 SAS 统计方法对大兴安岭北部地区兴安落叶松原始林的不同径阶胸径与边材面积之间的关系进行了探讨。结果表明:兴安落叶松胸径与边材面积的回归方程为 S=0.00098053D~2-0.09444D+25.05211, 且两者相关性显著。该结果为大兴安岭兴安落叶松的径流量测定提供一些参考依据。
【Abstract】 This article adopts SAS statistical method to discuss and analyse the correlation between differ ent DBH and sapwood area of Larix gmelinii primary forest in the northern area of the DaXingAnLing. The Results indicated that the Regression equation of DBH and sapwood area of Larix gmelinii S=0.0009 8053D~2-0.09444D+25.05211 and the relation of DBH and sapwood area of Larix gmelinii is notable,Whi ch provides some reference basis for Runoff research of Larix gmelini in the DaXingAnLing.
