摘　　要：刺槐(Robinia pseudoacacia)生长迅速,适应性强,耐干旱,树冠大郁闭早,枯枝落叶多易分解,改良土壤的作用明显,已成为陕西渭北地区的主要造林树种。多年来,许多学者的研究表明。The theory Ⅰ of quantification is used to deal with the correlations between site factors and biomass of litterfall and undergrowth plant in black locust stands in the Loess Plateau region of Shanxi province. The result shows that geomorphological type, soil type, slope direction, altitude, slope gradient, age and density of stand are important factors in determining the quantities of biomass.
