Difference in soil mite community characteristics among different vegetation restoration practices in the moderatly degraded pasture of Songnen grassland

摘要

Data on the soil mites living under different vegetation reclamation conditions in the moderately degraded grasslands were collected in Songnen between May to October in 2005. Community parameters such as generic richness, abundance, diversity index, and MI index were described, and community structure and its seasonal changes were studied. Our results showed that planting alfalfa, and fencing enclosures, substantially improved soil mite communities after five years reclamation. Soil mite diversity and MI index were also significantly higher after planting alfalfa than after fencing enclosures. The results suggested that planting alfalfa may more favourably restore soil mite communities than fencing enclosures in the moderately degraded grasslands of Songnen [ Acta Zoologica Sinica 53(4):607 –615, 2007].
