| 摘 要： | 应用敌百虫杀虫剂对南方农田土壤动物进行染毒模拟实验,共获得土壤动物679只,隶属1门20目1亚目,其中前气门亚目(Prostigmata)和弹尾目(Collembola)为优势类群,共占土壤动物全捕获量的54.93%,其余为常见类群和稀有类群。实验结果表明,随敌百虫处理浓度的增加,土壤动物的个体数量和类群数减少,Shannon-Wiener多样性指数(H’)和Pielou均匀度指数(E)均表现出递减趋势,而Simpson优势度指数(C)则递增。在一定的染毒历时(24~72 h)内,随着染毒时间的增加,所获得的土壤动物的类群数和个体数量呈下降趋势。 |

| Abstract: | By simulating test for effects of dipterex insecticide pollution on soil animals, a total of 679 soil animal individuals was collected, belonging to 1 phylums, 20 orders, and 1 suborder. The dominant groups were Prostigmata and Collembola, accounting for 54.93% of the total number of soil animals captured, and others were the ordinary groups and rare groups. The result showed that with the increase of dipterex concentration, the species and quantities of soil animal as well as the Shannon-Wiener diversity index and Pielou evenness index decreased, but the Simpson dominance index increased; And as the exposure time of dipterex increased (24 - 72 h), the species and quantities of soil animals decreased. |
