施药对寒地稻田节肢动物群落多样性的影响

Effect of Pesticide on Diversity of the Arthropod Community in Cold Rice Fields

根据田间系统调查,把稻田节肢动物群落按营养和取食关系划分为3个营养层和不同的功能集团。进而在物种、功能集团和营养层3个水平上对黑龙江寒地稻田节肢动物群落多样性进行了分析。结果表明:供试的稻田中,生态稳定性较好的是施生物药剂稻田,生态稳定性较差的是施化学药剂稻田。

On the basis of systematic investigation,the arthropod was divided into three nutrient layers and different groups in cold rice field,and the analysis of the structure and diversity of the arthropod community were performed on the levels of the species,function group and nutrient layers.The results showed that the ecological stability of biochemical field was the strongest,the worst was in the chemical rice field.
