蚯蚓对城镇污泥堆肥过程中微型动物群落演替的影响

采用实验对比和除趋势对应分析（DCA）等方法,以城镇污泥中的微型动物为对象,研究蚯蚓对堆肥过程微型动物群落演替的影响.结果表明,蚯蚓仅影响微型动物群落数量,对演替进程无明显影响.堆肥过程微型动物群落演替可分为3个阶段：第1阶段（0~10 d）,固着类纤毛虫为优势类群阶段,该阶段微型动物变化多受限于环境的改变,蚯蚓影响较小;第2阶段（10~30 d）,固着类纤毛虫和轮虫向肉足虫和线虫为优势类群的过渡阶段,该阶段蚯蚓对线虫数量有一定的限制;第3阶段（30 d后）,肉足虫和线虫为优势类群阶段,该阶段蚯蚓对有壳肉足虫的增长产生了明显的抑制作用.群落多样性指数结果显示,蚯蚓在第1和第2阶段作用不明显,在第3阶段增加了微型动物的多样性和均匀度,减小了优势物种的优势程度.对固着类纤毛虫的同化作用是蚯蚓稳定堆肥环境、促进有机质降解的重要因素.
