Abstract: Based on data of the soil animals survey in many year, the ecological characters of B.ocellatus are analyzed and described in present paper.The distribution of population density is concerned with the shadow below the forest, moisture and the thickness of the defoliation.The dynamics of population is related to the rainfall.If the rainfall were too little or too much, its population would be reduced.Its decomposition of the deadwoods and defoliation has remarkable influence on the energy transformation of the forest ecosystems.

Key words: burmoniscus, B.ocellatus, ecology
