摘要
本文应用数理统计法确定了单丛油蒿当年枝生物量与冠幅和高度间的线性回归方程及单枝油蒿、中间锦鸡儿当年枝生物量与枝长和基部直径间的线性回归方程。
By using statistical methods,we established some quantitative models for estimating an-nual branch biomass for individual Artemisia ordosica stands. Linear equations of branch biomass to the croun coverage and plant height were given for Artemisia ordosica and Linear equations of branch biomuss to branch leugth and branch basal diameter were given for Caragana intrmedia.
