| 中文摘要: |
| 经田间调查与室内鉴定，发现黑龙江寒地水稻田节肢动物种类有2纲10目49科65种。稻田节肢动物中各目、科的种类数量所占比例差异很大，在植食性昆虫中鞘翅目所占比例最大；在天敌中以蜘蛛类最多；在中性昆虫中，以双翅目比例最大；同时在物种、功能集团和营养层3个组织层次水平上分析了稻田节肢动物群落的结构和多样性。结果表明：在寒地稻田中顶位物种的丰盛度变化不大，而中位物种和基位物种的丰盛度变化明显；种的多样性整体变化幅度最大，8月9日最高，功能团多样性变化幅度不大，营养层多样性有一定波动。 |
| 英文摘要: |
| Based on field investigations and indoor identification, 65 arthropod species were found in cold rice fields, which belonged to 49 families in 10 orders of 2 classes. Coleoptera species accounted for the greatest share in phytophagous insects, and spiders were the major natural enemies. The largest proportion of neutral insects was dipteran. There was little change in top species richness, while obvious changes in the median and base species and species richness were observed. The biggest overall change took place in species diversity, with the peak on August 9. |
