Slope eco-restoration has always received extensive attention as a positive way to reverse ecosystem deterioration derived from human interventions.A simplified framework is proposed to undertake a quantitative evaluation of the engineering disturbed slope eco-restoration success in the alpine region,southeast Qinghai-Tibet Plateau.The Dagu hydropower project that disturbs the local ecosystem to some certain was 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.

提出了一种通过偏振模式耦合方式实现分布反馈光纤激光器保偏输出的方法,分布反馈光纤激光器是由刻写在有源光纤上的相移光栅构成的一种窄线宽光源.由于侧面紫外曝光过程造成的光纤极化,这种光纤光栅激光具有线偏振特性,但光路结构一般是由单模光纤构成,因此激光的线偏振特性无法保持.通过监测激光偏振耦合输出功率,可以间接识别激光线偏振方向,将激光线偏振方向和保偏尾纤二次耦合熔接,可以实现窄线宽分布反馈光纤激光的保偏输出.实验得到了偏振消光比大于30 dB,输出稳定线偏振光的分布反馈光纤激光器,且激光效率、线宽、噪声等较原
The Andean forests of northern Ecuador are known for their high levels of plant diversity relative to the area they occupy.Typically,these forests grow on steep slopes that lead to dramatic habitat gradients across short distances.These extreme habitat gr
