摘要: 对江苏省东台林场5种不同经营模式,包括银杏(G)、银杏+小麦(GW)、银杏+油菜(GR)、小麦(W)和油菜(R)土壤动物多样性进行调查,以了解不同经营模式对土壤动物群落的影响。试验中每种模式设置10 m×10 m样方,每个样方采用品字形取0~5 cm、≥5~10 cm、≥10~15 cm 3个层次的混合样,3月和6月共采集土壤样本90个,经Tullgren土壤动物分离漏斗分离并用75%酒精固定后获土壤动物7 069头,分属于5门9纲21类。通过对物种丰富度(S)、多样性指数(H)、均匀度指数(J)、相似度指数(Q)和密度-类群指数(IDG)5个多样性指数进行分析,结果表明不同经营模式的多样性指数存在显著差异,土壤动物的优势种群为弹尾目和蜱螨目。G、GW、GR的丰富度、均匀度、密度-类群指数都高于W和R模式,优势度指数较小。丰富度指数与密度-类群指数显著正相关,季节只对R模式的多样性指数存在显著影响。G与GW和GR模式的土壤动物群落相似性指数较大,与W和R模式的土壤动物群落相似性较小,W与R模式的相似性较小。试验表明,不同经营模式对土壤动物群落具有一定的影响,与纯农模式相比,银杏复合模式提高了土壤动物的多样性,优化了土壤环境。

Abstract: In order to understand soil fauna diversity of different planting patterns, the soil fauna diversity of five planting patterns, including Ginkgo biloba (G), G. biloba+Triticum aestivuml (GW), G. biloba+Brassica campestris (GR), T. aestivuml (W)and B. campestris (R), were investigated in March and June 2014 at Dongtai Forest Farm, Jiangsu Province, China. There were 7 069 soil animals obtained from 90 soil samples by Tullgren funnel and 75% alcohol, which belong to 5 phyla and 9 classes. Diversity indexes of soil animals in five planting patterns were analyzed, including species abundance(S), diversity(H), evenness(J), similarity(Q)and density-group(IDG), and the results showed that the diversity indexes of soil animals in five planting patterns had significant variation, and the dominant animal groups were Collembola and Acarina. H, j and IDG indexes in G, GW and GR planting systems were higher than that in W and R systems, while Q index was lower. There was significant positive correlation between H and IDG indexs. Season only affected diversity indexes of R pattern significantly. The Q index of G pattern was similar to GW and GR patterns, and it had significant variation with W and R patterns. So Ginkgo biloba agroforestry systems had significant effect on soil fauna communities, and interrcopping in Ginkgo biloba forest could protect the biodiversity of soil fauna.
