摘　　要：初步分析了在试验条件和自然状况下马(牛)粪的水分丢失和化学成分变化的特点以及与粪食性金龟子的关系.结果表明,试验条件下,无金龟子作用时,马粪的自然失水随时间成线性变化;在金龟子的作用下,失水减慢,特别是试验中使用12头虫的情况下,失水速度的减慢更加明显;试验条件下,经金龟子作用的马粪水浸液中的有机质含量有减少的趋势,灰分含量未减少,即金龟子可能主要取食马粪中的有机质;在自然情况下,马(牛)粪分解过程中化学元素的含量损失有两种情况,一种是含量损失由未分解阶段到半分解阶段较大,另一种是含量损失在由半分解阶段到分解阶段时较大,单位重量粪中灰分的含量随分解时间变化不大,但由新鲜粪便到完全分解灰分肯定是减少的,在粪的分解过程中,有机质的损失快于灰分.Under the experimental and natural conditions, the relationships between water losing and the changes of chemical components and dung beetles were analyzed. As non-activity of dung beetles,the process of water losing in horse feces is linearity to changes of time. The effect of dung beetles can make the process of horse feces water losing expedited,especially using 12 individuals in this experiment. By affect of dung beetles,the content of organic substance in horse feces lixivium is decrease. But the content of ash is not decrease. So in the process of horse feces decomposition,the function of dung beetles is likely to feed organic substance. Under the natural condition, the losing of chemical elements contents in horse（cattle） feces can be divided into two types. One is that the losing of the contents are quick in stage of under- composition to semidecomposition,another is the losing of the contents are quick in stage of semidecomposition to composition. In the process of horse feces decomposition, losing of organic substance is quick than that of ash.
