Study on the Vegetation Recovering Effect of Oily Soil after Bioremediation

摘要

The vegetation recovering effect of oily soil after bioremediation was studied and contrasted with the background of natural environment in this paper. The results indicated that the vegetation productivity of oily soil after microbial remediation can be restored to its original level, but is not enough to rely on natural recovery of vegetation. The unit productivity of oily soil only through microbial remediation was obviously lower than natural background, and the biocommunity and its vertical structure were relatively simple. But the unit productivity of oily soil after phytoremediation was nearly similar to the uncontaminated soil.
