摘　　要：为探究不同生态护坡对氨氮、磷酸盐的削减效果和规律,构筑了现浇绿化混凝土、生态砌块、格宾石笼、植物蜂巢、普通植草等5种不同生态护坡试验段并开展了径流模拟试验,分别监测了试验过程中地表径流、壤中流的水量水质变化过程。结果发现:以上5种生态护坡对氨氮、磷酸盐的削减率均较为显著;对氨氮、磷酸盐的综合削减率由大至小依次为植物蜂巢(68%,59%)、格宾石笼(54%,43%)、生态砌块(41%,38%)、现浇绿化混凝土(23%,13%)、普通植草(22%,12%);壤中流对氨氮、磷酸盐的削减率均显著高于地表径流。To explore different ecological slope protection on the cutting effect and regularity of ammonia nitrogen,phosphate,constructed of concrete,ecological greening block,stone cage bean,hives,ordinary planting grass five different ecological slope protection test section and simulation test was carried out by runoff,respectively,monitoring the test process of surface runoff,water quality change process of soil grains.The results showed that the reduction rates of ammonia nitrogen and phosphate were significant for the above five ecological slope revetments.The comprehensive reduction rate of ammonia nitrogen and phosphate from large to small is plant honeycomb(68%,59%),gabion stone cage(54%,43%),ecological block(41%,38%),cast-in-place green concrete(23%,13%),common grass(22%,12%);The reduction rate of ammonia nitrogen and phosphate in soil flow was significantly higher than that in surface runoff.
