Analysis on soil animals, soil respiration and the correlation in three forest ecosystems in Maoershan

Forest ecosystem is the largest organic carbon pool in terrestrial ecosystem, and its slight changes may cause significant variations in global climate. Soil respiration is the key ecological process of carbon cycle in forest ecosystem, which has a great influence on global climate change. Soil animals, as the important consumers of material cycle in the ecosystem, can regulate soil respiration the help of their own metabolism and affecting microbial activities. Therefore, study of the correlation of soil animals and soil respiration is of great significance to further reveal the law and mechanism of carbon cycle in ecosystem. Based on field experiment and indoor analysis, we chose soil respiration and soil animals in three forest ecosystems of Korean pine plantation forest(HS), Mongolian oak forest(MGL), and Hard-wood forest(YK) in Maoershan as the research object, and discuss the temporal variation and correlation between soil respiration as well as individual density or biomass of soil animals in different forest ecosystems. The results showed that:(1) the total soil respiration rate of the three forest ecosystems increased at first and then decreased(P
