In this experiment,a small test apparatus was designed to simulate the buffer strips. Five kinds of common arbors were selected and grouped into two different arrangements from the northeast region,to study the effects of different tree species and different arrangements on runoff and seepage nitrogen removal. The results showed that the nitrogen removal of the mixed planting of Phellodendron amurense and Fraxinus mandshurica(29. 77%)was better than the mixed one of Phellodendron amurenses and Acer ginnala(23. 89%); the mixed planting of Mongolian quercia and Acer ginnala(17. 07%) was better than the singal Phellodendron amurense(7%); the mixed planting of Euonymus alatus and Acer ginnala(7. 62%)was better than the singal Euonymus alatus(0. 52%).The average seepage flow removal rate of arrangement one(Phellodendron amurense,Acer ginnala,Mongolian quercia,Euonymus alatus)was 43. 48%,the second arrangement(Phellodendron amurense,Fraxinus mandshurica,Euonymus alatus)was 40. 54%,so the first arrangement was better than the second one.
