落叶松人工林胸径与叶生物量相关性研究

Study on the Correlation of Breast Diameter and Leaf Biomass of Larix Plantation

以关山林区引种的落叶松人工林为研究对象，在标准地调查的基础上，采用树干解析和分层切割破坏取样法，研究了该区6-15年生、胸径3-9cm落叶松人工林胸径与生物量的关系，结果表明：落叶松胸径和叶生物量间关系成直线关系，相关系数达到0．9364，生物量干质量y=0．2861D13-0．8107。

On the basis of investigation of sample plots in Larix plantation of Guanshan forest area, stem analysis and vertical stratifying method were employed to study the relationship of dbh and biomass of 15-year-old Larix plantation with dbh of 3-9 cm. The experiment results indicated that relation of dbh and biomass of Larix was linear. The correlation coefficient was 0.936 4, and the biomass dry weight y=0.286 1D1.3-0.810 7,
