摘　　要：于2010年1月28日在济南章丘浅井水稻田中进行了小型底栖生物的调查研究。结果表明,稻田冬季小型底栖生物的平均丰度为770±351ind·10·cm-2,平均生物量为692.3μgdwt·10·cm-2。共鉴定出6个小型底栖生物类群。按丰度,自由生活线虫为最优势类群,比例达94.9%;其他类群依次为桡足类、介类、缓步类、寡毛类、甲壳类,线虫分布在5～8cm的比例为40.3%。本研究为进一步了解小型底栖生物群落、种类组成,以及为淡水底栖生态系统结构和功能的深入研究提供参考。Investigation on the meiofauna about paddy feild of Jinan Qianjing was studied in January 2010（winter）.The results showed that the average meiobenthos abundance was 770 ± 351 ind·10·cm^-2, average biomass was 692.3 μg dwt·10·cm^-2.In our study, six groups of small benthic organisms were identified.According to the abundance, free-living nematodes were the most dominant group, which dominance was 94.9%, followed by Copepoda, Ostracoda, Tardigrada and Oligochaeta.Our studies could supply reference to the futher research on the small benthic communities, species composition, as well as the research on structure and function of freshwater benthic ecosystem.
