摘　　要：为探究多倍体剑叶芦竹在豫西丘陵区的生态治理效果,在三门峡义马市苗元村布设了多倍体剑叶芦竹、天然草本植物和乔木-草本植物的径流小区进行试验,通过3次降雨,对比分析多倍体剑叶芦竹对地表径流、泥沙、氮磷的拦截阻控效果。结果表明:1)多倍体剑叶芦竹对地表径流和泥沙的拦截效果优于天然草本植物,拦截效率分别高出4.24%~27.80%和93.77%~94.82%;相较于乔木-草本植物,剑叶芦竹对地表径流的拦截效率高出3.95%~29.27%,对泥沙的拦截效率与多年生高覆盖度草本基本持平。2)多倍体剑叶芦竹对TN、TP和NH_(3)-N的拦截效率比天然草本植物分别高出4.19%~29.70%、64.56%~95.00%和59.22%~76.52%,与乔木-草本植物的拦截效率相比分别高出89.41%~98.09%、85.03%~95.00%、89.41%~99.07%。研究证明,多倍体剑叶芦竹可以有效拦截径流、泥沙以及氮磷,在豫西丘陵区具有较高的水土保持、面源污染拦截能力。To investigate the ecological management effect of polyploid Arundo Donax L.in the hilly area of western Henan,polyploid Arundo Donax L.,natural herbaceous plant and arborvitae-herbaceous plants runoff plots were set up in Miaoyuan Village,Yima City,Sanmenxia,and the intercepting and controlling effect of polyploid Arundo Donax L.on surface runoff,sediment,nitrogen and phosphorus was analyzed through three rainfall comparison.The results showed that:1)the intercepting effect of polyploid Arundo Donax L.on surface runoff and sediment was better than that of the natural herbaceous plants,with the intercepting efficiency higher than that of the natural herbaceous plants by 4.24%to 27.80%and 93.77%to 94.82%,respectively;compared with the arborvitae-herbaceous plants,polyploid Arundo Donax L.’s interception efficiency of surface runoff was higher by 3.95%to 29.27%,but its interception performance on the sediment was nearly equal.2)the interception efficiencies of total nitrogen,total phosphorus and ammonia nitrogen by polyploid Arundo Donax L.were 4.19%to 29.70%,64.56%to 95.00%,and 59.22%to 76.52%higher than those of natural herbaceous plants,and 89.41%to 98.09%,85.03%to 95.00%,and 89.41%to 99.07%higher than those of arboreal-herbaceous plants.The study proved that polyploid Arundo Donax L.could effectively intercept runoff,sediment,and nitrogen and phosphorus,and had a high capacity for soil and water conservation,and non-point source pollution interception in the hilly area of western Henan.
