干撒PAM对黄绵土工程堆积体侵蚀泥沙的影响OACSTPCD
Effects of Dry Scattering PAM on the Erosion Sediments of Loess Soil Engineering Accumulation
为了探寻PAM(聚丙烯酰胺)的适宜干撒量,以减少工程堆积体的侵蚀泥沙和维持工程堆积体的稳定性,在黄土丘陵沟壑区,以不撒PAM(聚丙烯酰胺)为对照(CK),将0.5、1.0、1.5、2.0、2.5 g/m2的PAM干撒于圆锥状黄绵土工程堆积体的表层,监测自然降雨状况下PAM对黄绵土工程堆积体的地表径流、侵蚀泥沙、细沟发育和堆积体土壤水分含量等的影响.结果表明:不同处理的径流量、产流次数和径流系数均随PAM干撒量的增加表现为先降低后升高,其中干撒量为…查看全部>>
To explore the suitable amount of dry scattering PAM(polyacrylamide)to reduce the erosion sediments and maintain the stability of engineering accumulation,0.5,1.0,1.5,2.0 and 2.5 g/m2 of PAM were dry scattered on the surface of conical loess soil engineering accumulation in the loess hilly-gully region and with no PAM as the control(CK).The effects of PAM on surface runoff,erosion sediments,rill development and soil moisture of loess soil engineering accumul…查看全部>>
