摘 要 ：马陆是森林生态系统重要的分解者 ,在帽儿山林区 ,马陆摄食量随温度的升高而增加。据初步估算 ,马陆对凋落物的分解量约占该地区年平均凋落物量的 0 .2 1 %。马陆对同一种、不同腐解程度的叶片摄食量不同 ,对半分解凋落物的摄食量大于对未分解凋落物的摄食量。在不同温度条件下 ,马陆的生态效率不同 ,其同化效率随温度升高而降低 ,而粪便率则随温度升高而增加。在不同林型下个体数量分布不均匀。通常 ,阔叶林 >针阔叶混交林 >针叶林。在土壤的垂直分布上 ,具有明显的表聚现象。马陆的个体数量季节变化明显 ,以夏末最多 ,冬末最少。

Abstract:Millipedes is an important decomposer in the forest ecosystem. In Maoer Mount, the quantity of millipedes diet increase with the rising of temperature, The decomposition amount by millipedes, is estimated, to be 0.21% of annual litters amount. Their ingestion to semi decomposition leaves is more than that to undecomposed ones. Their assimilation efficiency is negatively relative to temperature, but the rejecta rate is positively relative to temperature. Its amount of individual is uneven in distribution,wi...
