帽儿山森林落叶分解消耗与土壤动物关系的研究

Relationship of litter decomposition and consumption with soil animals in Maoer Mountain forest.

１引言森林凋落物分解是森林生态系统物质循环和能量流动的重要环节，枯枝落叶分解是由多种因素作用的复杂过程．研究枯枝落叶在自然环境下的分解消耗及其与土壤动物的关系具有重要的生态学意义［４］，并对林业生产、营造人工林有一定的指导作用．在枯枝落叶分解研究中，...

The study shows that in Maoer Mountain, the rates of litter decomposition and consumption were higher in pure Pinus koraiensis forest than in P.koraiensis broad leaved mixed forest. In the course of litter decomposition and consumption, soil animals, and soil macrofauna in particular, played more important role than soil microbes. The seasonal variation curves of soil animal species and individuals were similar to those of litter decomposition and consumption rates, with the peaks in July, which indicated that the decomposition and consumption of litter was correlated with soil animals.
