Abstract：Experiments were carried out in excavating subsidence pool to study the purifying effects of Ipomoeaaquatic with different coverage (10%,20%,and 30%)for mining subsidence aquaculture wa-ter.Results showed that the pool with Ipomoea aquatic floating bed had significant better purification effect than that without Ipomoea aquatic floating bed on TN and TP.And with greater coverage,the floating bed reached better purification effect on TN,TP,NH+4-N,NO-2-N,COD.The present study showed that,mining subsidence aquaculture water was good purified by Ipomoea aquatic floating bed, and when the area of floating-bed was 30%,the ecological benefit achieved to the optimum level.
