Study on the effect of biochar for the construction and decontamination efficiency of submerged plant system

Ecological restoration in the dredging area has attracted increasing attention. Reconstruction of submerged plant ecosystem is an important method for aquatic ecosystem restoration.This study has systematically investigated the effect of biochar improved sediment on the plant growth and decontamination efficiency of constructed ecosystem. Microbial community composition and structure in the sediment were detected. The structure and function of microbial communities were different among submerged plants and biochar treatments. Our results proposed construction strategy of submerged plants in dredging area.
