摘要
本文研究了东北３种阔叶树落叶的分解与土壤动物在其分解过程中的作用。结果表明，３种枯叶的重量损失速度排序：水曲柳＞白桦＞蒙古栎。３种枯叶的半分解期及分解９５％所需时间分别为：水曲柳０．４年与１．７年，白桦０．９年与３．９年，蒙古栎为１．９年与８．２年。在枯叶分解过程中起主要作用的大型土壤动物有蚯蚓、线蚓、马陆、腹足类、昆虫及其幼虫；中小型土壤动物有线虫、螨类、弹尾类等３０余种。
In this paper the fallen leaves decomposition of three kinds broadleaved trees and the function of soil animals in the decomposition process have been studied.The result showed that theweight losses speed of three kinds dead leaves as follows:Northeast China Ash>White Birch>Mongolian Oak.The periods of half decomposition and the time of ninety-five percent decomposition of the dead leaves of this three kinds as follow.Northeast China Ash 0.4～1.7 years,White Birch 0.9-3.9 years,Mongolian Oak 1.9～8.2 years.Among large soil animals,Earthworm, Enchytraeid,Diplopoda,Insect(lara) play an important role in the decomposition process of dead leaves,so do Nematoda,Acarina,Collembola and other more than thirty kinds among small-medium soil animals.
