| 摘 要： | 本文报道了北京地区辽东株群落的建群种──辽东烁呼吸量的研究结果。详细论述了用红外ＣＯ＿２分析仪测定林木呼吸速率的方法和技术，给出了辽东栎非同化器官的直径分布函数表达式、呼吸速率与直径的关系以及计算单株林木各器官总时吸量的表达式，建立了由每木调查结果推算群落呼吸量的方法。结果表明：胸径大于４．０ｃｍ的辽东杆每年呼吸释放的ＣＯ＿２为１０．２ｔ／ｈｍ￣２，其中根、茎、叶、枝分别为２．８，１．７，２．６，３．２ｔ／ｈｍ￣２。本文论述的方法和技术不仅对研究森林呼吸量，对测定森林释放其它气体也有参考意义。

| Abstract: | espiration amount of Quercus liaotutungensis, a dominant species in Q. liaotungensis com-munity located in Beijing,was studied in the present paper. The method and technigue ofmeasuring the respiration rate of organs of trees by using a CO_2 gas analyzer were noted insome details,and two basic formulae for woody organs,diameter frequency distribution func-tion and the relation of the respiration rate to its diameter, were given. Baded on these twoformulae, the authors built an equation for the calculation ... |
