[Animal community structure in greenhouse soils with different planting years in Shouguang City].
By the methods of hand-sorting, Tullgren's and Baermann's, the animal community structure in greenhouse soils with different planting years in Shouguang City of Shandong Province was investigated from March 2006 to April 2007. A total of 20966 soil animals belonging to 3 phylums and 12 classes were obtained. Collembola, Nematoda, Acariformes and Oribatida were the dominant groups, accounting for 82.3% of the total individuals. The soil animals had an obvious vertical distribution pattern, with most of them assembled in surface soil and occupying 75.4% and 14.6% of the total at the depths of 0-5 cm and 5-10 cm, respectively. The animals' amount in greenhouse soils was the highest from March to May and from October to December, and the lowest in August; while that in open field soils was the highest from July to September, and the lowest in January. The animal community in greenhouse soils in this region had a high diversity, but the density of dominant groups increased obviously with increasing planting years, resulting in a decrease of diversity index.
