摘要：Agricultural runoff caused great pollution on water environment. In present study, contraposing the purification efficiency for 3 kinds of sward-buffer to runoff pollutant. The results showed that: Exposed riparian land has no reduce effect for SS in runoff, and the ratio for a 19 meter one is above 80%, the most efficacious sward is Cynodon dactylon, the reduce ratio can reach 84%, and the following are Trifolium repens and Festuca Arundinacea, the reduce ratio of which are respectivly 81% and 73%; when the influent TN concentration is lower than 10 mg·L-1, the effluent TN concentration of seepage water of four buffer strips all lower than 2 mg·L-1, which all reach the Grade V of Surface Water Environmental Quality Standards (Chinese EPA, 2002); when the influent TP concentration is almost 0.9～1.0 mg·L-1, the effluent TP concentration of seepage water of four buffer strips is almost 0.08～0.34 mg·L-1, which all lower than Grade V of Surface Water Environmental Quality Standards (Chinese EPA, 2002); through the simulating formula, the optimal width for 3 kind of sward-buffer is 16.1～20.4m when the the decrease ratio of ss is 80%, in which Cynodon dactylon is the most efficacious one. ? 2011 IEEE.
