摘　　要：本研究针对当前寒区堤防护坡优选主观经验决策的局限性,以哈尔滨市阿什河干流道为例,构建多指标评价体系,引入熵权系数评价模型对不同堤防护坡方案进行优选。结果表明:熵权系数模型可将主观经验和客观信息有机结合,计算结果更为科学可靠;不同堤防护坡方案以铰链生态护坡熵权系数评价值最高(综合效益最优),达到0.993,可作为阿什河干流道外香坊段堤防护坡的主要方案。In view of the limitations of subjective experience decision-making in the optimization of embankment protection slope in cold regions,this study takes the main channel of Ashi River in Harbin as an example,constructs a multi-index evaluation system,and introduces the entropy weight coefficient evaluation model to optimize different embankment protection slope schemes.The results show that the entropy weight coefficient model can organically combine subjective experience and objective information,and the calculation results are more scientific and reliable.In addition,the entropy weight coefficient evaluation value of hinge ecological slope protection is the highest(namely comprehensive benefit is the best),reaching 0.993,which can be used as the main scheme of embankment slope protection in Xiangfang section of the main channel of Ashi River.
