Relationships in diversity of soil meso-fauna and soil moisture conditions were investigated in some types of drip irrigation plots and tube irrigation plot in green house. Water content and soil, animal population, number of genera, diversity index of Simpson (1/lambda) and that of Fisher (alpha + 1) were measured. The results showed that both standard irrigated plot in drip irrigation and underground water irrigation plot showed stable conditions of diversity indices, and moisture conditions were stable. But populations and number of genera in the standard irrigated plot were much larger than in the underground one. Low and Less irrigated plots showed unstable conditions of diversity indices and soil moisture. Therefore, we concluded that stable soil moisture condition is useful for balancing soil animal's diversity, but not for the population and number of genera.
