摘  要:
以沈阳市典型河流两岸植被缓冲带为对象,对地表径流中全氮、全磷污染的消减效果进行研究,结果表明:天然植被比人工植被能更好地吸收地表径流中的N、P污染物,林草混合地比单独的林地或草地能更好地吸收污染物;各类型的河岸植被缓冲带对P的削减效果优于对N的削减效果。人工林草地、天然草地以及天然林草地对总氮的削减效果较好,各样地带对总磷的削减率无显著差异。随着污染负荷的增加,不同类型的河岸植被缓冲带对地表径流中的总氮、总磷的削减作用逐渐增强。

摘  要:
Typical vegetation riparian buffer strips on both sides of river in Shenyang had been taken as the objects,and reduction effect research to total nitrogen and phosphorus pollution in surface runoff had been conducted,the results indicated that natural vegetation could absorb N and P pollution in surface runoff better than artificial vegetation,forest-grass land could absorb pollutant better than woodland and grassland;the reduction effect of all types of riparian buffer strips to P were superior to N.Plantation grassland,natural grassland and natural forest grassland reflected a preferably reduction effect of total nitrogen,and there was no significant difference of total phosphorus.With the increase of pollution load,the reduction effect of different types of riparian buffer strips to total nitrogen and phosphorus were ever-increasing.
