摘　　要：为明确适用于伊犁生态敏感区域的边坡生态修复植物,探究生态修复植物的实际修复效果,通过实地调研以及文献调研建立乡土护坡植物库,基于层次分析法(AHP)确定了生态修复植物组合,并开展了现场生态修复试验,构建植被护坡工程质量评价体系,并结合室内外试验对生态修复效果进行了评价,从护坡功能、生态效益、景观效果、经济效益4个方面确定植被护坡工程评价指标,基于AHP确定了各生态修复评价指标权重,结合综合评价指数法计算出生态修复评价分值。结果表明:伊犁地区植物种类丰富,沿线边坡植物平均冠长为16.3 cm,平均根长为6.65 cm,植被数量从坡顶到坡脚的位置呈现出递增的趋势;乡土护坡的生态修复植物确定为高羊茅、紫花苜蓿、狗尾巴草、狗牙根、野菊花5种植物;边坡Ⅰ综合评价分值为6.57,植被护坡等级评价为良,边坡Ⅱ综合评价分值为8.68,植被护坡等级评价为优,边坡Ⅱ的生态恢复效果比边坡Ⅰ理想。结果为西北伊犁生态敏感地区的生态修复提供了科学的草种选取依据以及工程边坡生态修复的评价方法。To identify suitable plants for slope ecological restoration in the ecologically sensitive areas of Ili and assess their actual effectiveness,a local slope protection plant database through field surveys and literature reviews is established.Using the Analytic Hierarchy Process,the combination of ecological restoration plants is determined and on-site ecological restoration experiments are conducted.A quality evaluation system for vegetation slope protection projects is constructed and the ecological restoration effect by combining indoor and outdoor experiments is evaluated.The evaluation indicators is determined for vegetation slope protection engineering based on four aspects:slope protection functions,ecological benefits,landscape effects,and economic benefits.Based on the Analytic Hierarchy Process,the weights of various ecological restoration indicators are determined and the ecological restoration evaluation scores are calculated by using the comprehensive evaluation index method.The findings revealed that the Ili region boasts a rich variety of plant species.Along the slope,the average crown length of plants is 16.3 cm,and the average root length is 6.65cm.The vegetation count increases from the top to the foot of the slope.The ecological restoration plants for local slope protection were identified as Festuca elata Keng,Medicago sativa,Setaria viridis,Cynodon dactylon and wild Chrysanthemum.The comprehensive evaluation score of the slope I was 6.57,with a vegetation slope protection grade evaluation of good.The comprehensive evaluation score of the slopeⅡwas 8.68,with a vegetation slope protection grade evaluation of excellent.The ecological restoration effect of slopeⅡis more satisfactory than that of slope I.These results offer a scientific basis for selecting grass species and an evaluation method for ecological restoration of engineering slopes in the ecologically sensitive areas of northwest Ili.
