摘要
利用吕梁山森林经营局１６４块标准地和７１９株辽东栎样木资料，通过二元、一元材积式，并选择最佳的胸径—根径回归关系式，编制出辽东栎立木根径材积式（表），此表可在吕梁山森林经营局辽乐栎林中使用。
Stump diameter volume table for Quercus liaotungensis was constructed on the basis of measurements on 164 sample plots and 719 sample trees,d b h volum functions,and optimum regression model of d b h and stump diameter It can be used for Quercus liaodungensis in Mt Luliang region,and the method of construction may be applied in other tree species or in other areas
