| Outline of Final Research Achievements |
The relationship between the stability of each enzyme production against disturbance and the species diversity of soil microbial community was investigated for the enzymes involved in carbon, nitrogen and phosphorus cycles. As a result, it was suggested that the effect of species diversity of soil microbial communities on the stability against soil disturbance depends on the type of enzyme activity. The β-D glucosidase activity involved in carbon cycle was the only positive correlation between the stability of enzyme activity and the species diversity of soil microorganisms in all soil samples. The same tendency was observed from the results of experiments related to the decomposition of organic matter in soil, suggesting that the stability of microbial functions related to carbon cycle to disturbance may depend on species diversity.
