灌木林地上部生物量计算及与立地条件的关系研究——以沙棘林为例

A Study on the Calculation of Shrub Biomass and the Relationship Between shrub Biomass and site EstabIishing Conditions——Taking Hippophae Rhamnoides forest as example

本文通过对沙棘的生理特性及生态功能研究,分析了树龄与沙棘林生物量及各生长因子的关系。并分析了立地条件对地上部生物量的影响,建立了用生长因子预测地上部生物量的回归模型。

Based on the study on Hippophae rhamnoides forest physiological characteristics and ecological function. This puper analysed the relationship of tree's ege and groth fastors and Hippophae rhamnoides biomass and effect of site establishing conditions on the above--ground biomass; and finally, regression models predictjng the above--ground biomass was repectively established using groth factor.
