摘要

<正>通过对岷江上游理县境内辽东栎(Quercusliaotungensis)天然次生林生物量和生产力测定与研究,结果表明:辽东栎天然次生林生物量为488.49t/hm2,其中乔木层生物量占绝对优势,达林分总生物量的99.22%,其余依次为枯枝落叶层、灌木层、苔藓层和草本层;乔木层中各器官生物量由大至小排序为:树干材、树枝、树根、树皮、树叶、果实;不同根系部位生物量由大至小为:根桩、粗根、中根、细根。灌木层不同部位生物量由大至小为:根、干枝、叶,草本层根的生物量大于地上部分生物量,枯枝落叶层的生物量大小依次表现为落叶、枯枝、落果。

Abstract

According to the measure and research on the biomass of natural secondary Quercus liaotungensis stand in Lixian county at the upper reaches of Minjiang river,the results are as follows:(1)natural secondary Quercus liaotungensis stand biomass reaches 488.49 t/hm2,in which the arborous layer biomass is occupying 99.22% of the total and the sequence of other layers is:litter layer>shrub layer>moss layer>herb layer;(2)In the arborous layer biomass,the order of different organs is:stemwood>branch>root>bark>leaf>fruit,and that of root biomass is:root neck>thick root>middle root>thin root;(3)In the shrub layer,the order of different parts is:root>stemwood and branch>leaf,that in the herb layer is:root>the aboveground parts,while that in the litter layer is:fallen leaves>deadwood>fallen nuts.In addition,the vertical distribution of Quercus liaotungensis biomass has also been studied.
