石朱桥水库边坡生态修复效果评价研究

Effect Evaluation of Conservation of Ecological Restoration Slope of Shizhuqiao Reservoir

研究边坡生态修复效果评价体系,可为科学合理地选择边坡生态修复措施提供理论依据。根据评价目标选取了10个重要的评价指标,建立由目标层、准则层、指标层组成的评价体系,运用层次分析法得出各指标的权重,结合石朱桥水库四个不同边坡的实际情况,由综合指数模型计算各个边坡生态修复效果的综合评价值。四个生态修复边坡的效果综合评价值分别为框格梁生态袋植草技术(0.9695)、植被混凝土+生态棒修复技术(0.8067)、高次团粒喷播技术(0.6170)、液压喷播草种(0.4299)。评价结果与实际情况相符,所构建的指标体系可以应用到其它边坡生态修复效果的定量分析中去。

Studing the evaluation system of slope conservation effect, which can provide a theoretical basis for scientific and rational selection of slope ecological restoration measures. According to the evaluation target, 10 important evaluation indexes are selected, and the evaluation system is established. It is composed of target layer, criterion layer and index layer.Then use AHP to get the weight of each index. In combination with the actual situation of four different slopes of Shi Zhu Qiao reservoir, the comprehensive evaluation values of conservation effects of each slope are calculated by the comprehensive index model. The comprehensive evaluation values of soil and water conservation effects of four ecological restoration slopes were: Eco bag planting in the frame(0.9695), Eco-bar restoration technology of vegetation concrete(0.8067), High order seed spraying technique(0.6170), Sow grass(0.4299).The evaluation result is consistent with the actual situation, so the constructed index system can be applied to quantitative analysis of soil and water conservation effects of other slopes.
