摘　　要：Slope eco-restoration has always received extensive attention as a positive way to reverse ecosystem deterioration derived from human interventions.A simplified frameworkis proposed to undertake a quantitative evaluation of the engineering disturbed slope eco-restoration success in the alpine region,southeast Qinghai-Tibet Plateau.The Daguhydropower project that disturbsthe local ecosystem to some certainwas selected as the study area.Since August 2018,six types of slope(soil,rock,soil-rock,spoil,construction site,hardened)were served as the demonstration test for the slope eco-restoration with two years monitoring in the study area.Meanwhile,the topography,erosion,soil quality,and vegetation were selected as assessment indicators of the methodology.Finally,combined with the weighting method and the expert panel,the slope eco-restoration quality index(SERQI)was established and applied in the six slopes.The results suggested that the frost-resistant ecological substrate performed well in alpine region,and the SERQI value is in accordance with the actual monitoring level with spoil slope>soil slope>construction site slope>soil-rock slope>rock slope>hardened slope.The proposed framework could support slope eco-restoration practitioners for making a more objective and quantitative evaluation easily for the post-implementation restoration.
