摘要
应用综合集成赋权法进行城市景观河道坝系布局方案优选,选取逼近理想点法计算指标的客观权重,选用区间映射赋权法(G2法)并加以改进后计算指标的主观权重,通过基于单位化约束条件的"加法"集成法得到兼顾主客观信息的综合权重,再借助该权重进行综合评估,确定坝系布局方案优先顺序。应用实例表明,应用综合集成赋权法得到的综合权重和坝系布局方案优选结论能够兼顾主客观影响因素,具有较好的推广应用价值。
The combining weight method was applied to the optimization of layout schemes for dam system of urban landscape rivers.The TOPSIS was employed to calculate the objective weight,and the interval mapping weighting method(G2 method) was improved to calculate the subjective weight.By use of the linear integrated method based on the unitized constraint conditions,both the objective weight and the subjective weight were integrated into the comprehensive weight,by which comprehensive evaluation was performed and the optimization of layout schemes for the dam system was determined.The results show that the comprehensive weight and the optimization of dam system layout achieved by the combining weighting method consider both the subjective and the objective factors.The proposed method is scientific,agile,simple and applicable.
