摘要
1995～ 1996年对黄河三角洲 9个代表性样区 ,进行了土壤动物定性、定量调查 ,并对古代、近代、现代黄河三角洲 3个代表性样区开展了土壤动物周年调查 ,研究了土壤动物的种类组成、分布和季节变化 ,以及土壤动物多样性。调查研究结果 :黄河三角洲共鉴定出土壤动物 38种 ,土壤动物种类组成和数量分布因三个三角洲成土年龄不同而存在差异 ,土壤动物多样性以夏季为丰富。黄河三角洲土壤动物多样性与均匀度表现为正相关关系 。
Based on qualitative and quantitative investigations of soil animals in nine sampling areas of the Yellow River Delta (YRD) made from 1995 to 1996 and yearly investigations made in the same period of soil animals in three sampling areas of ancient, recent and contemporary YRDs, the species composition, distribution, seasonal changes and diversity of soil animals have been characterised. In the YRD,38 species of soil animals have been identified,most belong to the orders Acarina, Coleoptera and Collembola. According to different sampling methods, 19 species of large soil animals, 31 species of medium-small Tullgren soil animals and 3 species of medium-small Baermann soil animals have been identified. The species compositions and distributions in the three YRDs are different because of the age of soil formation. So are the seasonal species compositions and distributions, the soil animal in summer being richest in diversity. The index of diversity of soil animals in the YRD is correlated with the index of evenness, but is negatively correlated with the purity.
