德阳市3种林草模式下土壤动物群落特征
The characteristics of soil fauna communities in three forest-grass patterns in Deyang,China
摘要
Abstract
This study was conducted to study the composition and community structure of soil fauna in three types of forest-grass patterns (J uglans regia +Medicago sativa ,Cichorium intybus and Dactylis glomerata ), and a pure Juglans woodland was applied as a control group in Deyang,Sichuan Province.The results showed that,A total of 303 specimens of soil faunas was found in this study,which were belonged to 3 phylum,7 clas-ses and 17 orders.Of those,Nematoda,Hymenoptera and Acarina were the dominant groups.The soil fauna was found to gather on the surface of earth in three types of forest-grass pattern,while the order of soil fauna density was 5 — 10 cm > 10 — 15 cm > 0 — 5 cm.In addition,the diversity of Shannon-Wiener index and DG (Density-groups)index of soil fauna was the highest in the J .regia +M .sativa pattern while the lowest DG index in pure woodland that possessed the highest Pielou index;The J .regia +M .sativa pattern has a signifi-cant difference to the pure woodland pattern in individual number of soil fauna,but on the area of species of groups are similar to the pure woodland pattern,and it had a highest proportion of Saprozoic fauna in four pat-terns.In summary,the three forest-grass patterns can enrich the composition of soil fauna communities,and highest abundant soil fauna was observed in J .regia +M .sativa pattern.关键词
