对豫东黄河故道湿地土壤动物进行调查与鉴定,研究其动物群落组成及多样性变化,为揭示黄河故道湿地生物多样性及其功能提供基础资料。结果表明,采集到的湿地土壤动物隶属5门8纲23目35类群,优势类群2类(线虫和膜翅目昆虫),常见类群11类,稀有类群22类。多样性分析表明,土壤动物群落个体数、类群数和丰富度指数最大值均出现在7月份,多样性指数和均匀度指数11月份最大。土壤动物功能类群在数量比例关系表现为腐食性土壤动物最多,其次为捕食性土壤动物,植食性土壤动物最低。
Investigate and identify the wetland soil fauna in the old course of the Yellow River in the eastern part of the Yellow River, study its composition and diversity of animal communities, and provide basic data for revealing the biodiversity and its functions of the wetland in the old course of the Yellow River. The results showed that the collected wetland soil animals belonged to 35 groups of 8 classes, 23 classes, 5 classes, 8 classes, 2 dominant groups (nematodes and Hymenoptera), 11 common groups and 22 rare groups. Diversity analysis showed that the maximum numbers of individuals, groups and richness index of soil fauna all occurred in July, and the diversity index and evenness index were the largest in November. Soil fauna functional groups in the proportion of the proportion of the performance of the largest number of rotting soil animals, followed by predatory soil animals, herbivores the lowest soil animal.
