摘要：In order to investigate the rhizosphere effect caused by the aquatic macrophyte Scirpus validus during the phytoremediation process of decabromodiphenyl ether contaminated sediment, the sediment microbial number changes in three typical sediment rhizosphere, including bacteria, fungi and actinomycetes were examinated. The results showed that the number of microorganisms in sediments was significantly increased by planting and the number of bacteria and fungi increased by 2-12 times and 1-4 times in the respective rhizosphere sediment. No obvious difference of quantity of actinomycetes was observed between rhizosphere and non-rhizosphere in silt and clay sediments expect for sand sediment. The results suggested that the numbers of microorganisms can be stimulated by the presence of S. validus and the rhizosphere effect was obvious.
