| Three bank slope forms也linear slope type(S), convex type(C), ladder-type(L)页effects on the change of nitrogen concentration in the runoff were studied. The results showed that the nitrogen concentration in the runoff of the three bank slopes from high to low wasS>C>L, so the carrying capacity of L was the best in the three bank slope forms. In addition, when the rainfall intensity was greater, the mean difference of the nitrogen concentration on the sampling points of L was maximum, it reflected that the interception effect of L for the nitrogen concentration in the runoff was the best. Moreover, whether the vegetation covered, L still showed the greater rejection. In summary, the study of the different bank slope forms effect on the transport and transformation of nitrogen in runoff was very important.Meanwhile, this study had certain theoretical significance and practical value to the following bank slope governance. |
