The control effects on non-point resource pollution combined with single rainstorm were studied at a reservoir by series of detention pond
wetland
dam and buffer strip. The results shows that about 80% rainstorm peak flow could be cut down when the runoff across the series BMPs. The detention pond is effective on the reduction of TSS which the removal rate is over 60% but have no obvious effect on the BOD5 and TN
while the wetland and buffer strip can effectively remove the BOD5 and TN
the removal rate is about 50~70%. In the whole system
