通过在采矿塌陷形成的养殖池塘放置覆盖率分别为10%、20%、30%的竹叶草，研究了竹叶草对采矿塌陷养殖水域的水质修复作用。结果表明，放置了竹叶草浮床的池塘中总氮(TN)和总磷(TP)含量显著低于未放置竹叶草的对照组池塘，且浮床覆盖率越大，对水体中 TN、TP、氨氮(NH4+-N)、亚硝氮(NO2--N)、COD净化效果越好。本研究表明，利用竹叶草浮床可有效去除采矿塌陷水体 N、P 等营养物质，并且竹叶草覆盖率为30%的效果更明显。

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.
