在工程沿线，共调查了13个弃渣场样地，采用了“五点取样法”，测定了样地内的乔木、灌木和草本层的相关指标，对样地内生态恢复措施效果进行了评价。工程采取的生态恢复措施中，紫穗槐等灌木层和草本层结构对渣场水土保持早期发挥了重要作用，乔木层长势缓慢，发挥作用受限，应该增加对渣场区域土层结构改良，提高渣场区域生态恢复和水土保持效果。

Along the project,13 slag field plots were investigated.And the “five point sampling method”was adopted to determine the related index of the arbor,shrub and herb layer within the plots.Then the evaluation of effect of ecological restoration measures of the plots was done.The results are that shrub layer and herb layer structure of the slag fields early played an important role in soil and water conservation in the ecological recovery measures,but the tree layer slow growth play the role of limited.So the soil structure of the slag fields should be improved to improve the effect of ecological recovery and soil and water conservation.
