中文摘要	把白刺地上部分区分为新枝、老枝Ⅰ、老枝Ⅱ和枯枝4种样枝类型,建立了其生物量与枝高、地径的关系模型,研究了总生物量与各器官生物量、叶面积之间的关系.结果指出,新枝总生物量(y)与最大枝高(Hm)、最大地径(Dm)的关系可用方程y=a(Dm2Hm)b表示,老枝Ⅰ和老枝Ⅱ的总生物量(y)与最大枝高(Hm)的关系可用方程y=aHmb表示.枝生物量(y)与白刺总生物量(x)之间的关系可模拟为y=aEXP(-bxk),叶生物量、叶面积(y)与总生物量(x)关系均可模拟为y=a+b(1-EXP(-kx)).通过研究确立了在乌兰布和沙漠估计和预测白刺地上生物量和叶面积的方法.
英文摘要	In the paper the aboveground part of Nitraria tangutorum was divided into four types, new branch, old branch I, old branch H and withered twig. The relationship model between the biomass and the branch height and (or) the ground diameter was established; the relationship between the total biomass and the individual biomass of aboveground parts or leaf area for different types was studied. The results showed that relationship between the total biomass (y) and the maximum branch height (Hm), the maximum ground diameter (Dm) of new branch could be expressed by equation y = a(D2mH’J . The relationship between the total biomass (y) and Hm of old branchlor old branch H could be expressed by y = aHbm. The relationship between the branch biomass and the total biomass could be expressed by y = aEXPf- bxk). The relationship between the leaf biomass(or the leaf area) and the total bio-mass could be expressed by y = a + bfl-EXP(- Axe)). Therefore, we have established the method of estimating and predicting the biomass of aboveground part of Nitraria tangutorum and leaf area for Wulan Buh desert.
