    摘要:

    本文测定了中国科学院红壤生态实验站内林地、不同施肥制度的红壤旱地和受有机农药污染地的土壤微生物生物量,探讨了土壤微生物生物量作为红壤生态系统土壤质量生物指标的可行性。结果表明,土壤微生物生物量能够灵敏地反映出不同植被对红壤生态系统的修复或重建作用,反映了不同施肥制度对红壤可耕地培肥作用的差异,以及检测出多效唑和杀虫眯对土壤的污染。因此,土壤微生物生物量可以作为红壤生态系统土壤质量的生物指标。

    Abstract:

    The soil microbial biomass carbon and nitrogen were measured in three long-term expenments,the different vegetation remediation experiment in red earth ecosystem, the experiment of red earth highland with different fertilization systems and the pollution experiment of Pacloutrazol and Chlordimeform, in the Red Earth Ecosystem Experimental Station, Academia Sinica. Results showed that soil microbial biomass could be sensible to indicate the effects of four types of vegetation on the bio-remediation of the degraded red earth ecosystem, to show the different effect of fertilization system on the fertility of red arable lands and to detect the pollution of Pacloutrazol and Chlordimeform applied to the red earth. Thus, the conclusion that soil microbial biomass may be as a bio-indicator of soil quality in the red earth ecosystem could be drawn.
