【摘要】 土壤原生动物具有丰富的种类多样性和巨大的生物量 ,在土壤生态系统中具有十分重要的地位。因此 ,其种类和数量的变化可指示环境质量的状况及发展趋势。与其它土壤生物相比 ,原生动物的一些特征使其更利于成为监测生物。土壤原生动物各类群在环境监测中的作用是不同的。有壳肉足虫和纤毛虫更适合作为土壤环境的指示生物。土壤原生动物在农田生态系统、森林生态系统等环境监测中已经有了一些应用 ,但与在水体环境监测中获得广泛应用的水生原生动物相比 ,土壤原生动物用于环境监测才刚刚起步。土壤原生动物分类学研究的滞后和方法学上的欠缺是阻碍其作为监测生物的瓶颈。相信随着这些问题的逐步解决 ,土壤原生动物在环境监测中必将发挥越来越大的作用更多还原

【Abstract】 Soil protozoa are an essential component of soil ecosystems because of their high biomass and considerable species diversity. Accordingly, studies of their population dynamics and community structures can provide a powerful means for monitoring changes in the environment. Several unique features favor the use of soil protozoa as bioindicators and they have been used for this purpose in agriculture and forest ecosystems. But, in comparison to freshwater protozoa which have been widely used as indicators in various freshwater ecosystems, the use of soil protozoa as monitors of the environment has just begun. The importance of different groups of soil protozoa in environmental monitoring varies. Ciliates and especially testate amoebae, whose abundance and diversity can be reliably estimated, should be preferred in environmental studies. There are also some methodological and taxonomic problems which limit the use of soil protozoa as bioindicators. When these are solved, soil protozoa will have great potential as bioindicators in the future.更多还原
