摘要
应用金丝柳、紫穗槐、毛柳植物材料对40m人工边坡进行生态修复性试验,调查与监测这3种植物材料的生长状况,并对其进行适宜性评价。结果表明:1)采用扦插措施,金丝柳的基径与毛柳的基径存在显著性差异,毛柳平均基径比金丝柳小33.3%,金丝柳的株高与紫穗槐的株高存在显著性差异,紫穗槐平均株高比金丝柳小33.3%。2)采用灌丛垫措施,紫穗槐的基径与金丝柳的基径存在显著性差异,金丝柳比紫穗槐的平均基径小18.2%,株高的生长情况3种植物无明显差异。在扦插和灌丛垫措施下,金丝柳、毛柳表现出良好的适应性,而紫穗槐适用于灌丛垫措施。
In order to investigate and monitor the positive effects of soil bioengineering technology on ecological restoration of river in local areas,species like Salix alba var.tristis,Amorpha fruticosa L.and S.matsudana were selected as the experimental plants applied on the 40m-length artificial slope.By summarizing ecology characteristics of these species,we valued the suitability of soil bioengineering carried on the slope land.Results indicate that： under the measure of living cutting,the diameter of S.alba var.tristis and S.matsudana vary greatly;the average diameter at breast height（DBH）of S.alba var.tristis is 22.5% higher than that of S.matsudana;there is a big difference between the height of S.alba var.tristis and A.fruticosa L,the average DBH of S.alba var.tristis is 33.3% higher than that of A.fruticosa L.While under the measure of brush mattress,the average DBH of S.alba var.tristis and A.fruticosa L.vary significantly;the average DBH of A.fruticosa L.is 18.2% higher than that of S.alba var.tristis;there is no significant difference in height among these three species.Both S.alba var.tristis and S.matsudana show good adaptability under measures of living cutting and brush mattress,while A.fruticosa L.under the measure of brush mattress performs the best.
