摘要: 对贺兰山东麓天然灰榆疏林林分进行了调查研究。实测灰榆单株的地上和地下生物量,应用相关分析方法,探讨灰榆单株各器官生物量与树高(H)、胸径(D)、1/2 树高处直径(D1/2)和胸径平方乘树高(D2H)的相关关系,结果表明:1)贺兰山东麓天然灰榆疏林单株各器官生物量分配比率为树干>树根>树枝>树皮>树叶。2)各器官生物量拟合的预测模型中,树干、树枝和树叶的生物量预测模型拟合效果较好,而且具有一定的实用价值;树枝和树皮的生物量预测模型拟合效果一般;任一自变量与单株生物量拟合的预测方程适用性均较好。

Abstract: Based on the biomass of average tree and the forest inventory data,determination was made on above and under ground biomass of a single tree from Ulmus glaucescens of Helan Mountains,and through the method of recession analysis,a study was conducted on the relation among each organ biomass and tree height(H),diameter at breast height(D),diameter at 1/2 total height(D1/2)and D2H.The result showed that the biomass distribution ratio of each part of Ulmus glaucescens of Helan Mountains was in the order of trunk > root > branch > bark > leaf.Trunk,branch and leaf biomass recession models were well fitted;root and bark biomass recession models were fitted not as well as the other models.Any independent variable number and biomass fitting prediction equation applicability are preferable.

Key words: biomass, recession models, Ulmus glaucescens, Helan Mountains
