摘　　要：考虑到桥梁景观评价过程中的不确定性和复杂性因素,基于集对分析理论,引入了能体现系统确定性与不确定性的同异反联系度(IDC)的计算公式,并建立了以桥梁景观为评价对象的集对分析模型(SPAM).模型从两个层次阐明集对分析理论的具体意义并将多指标表达成一个从总体上衡量桥梁景观的5元联系数;利用层次分析法确定指标权重,从主客观两方面定量计算桥梁美观程度.将SPAM应用于葫芦河特大桥的景观评价.结果表明:就总指标来说,桥梁景观评价等级为"二级(良)";就各个子系统来说,桥梁美学、造型和环境协调性相对好于其它三个指标.SPAM模型可以较好地处理研究对象中所包含的不确定性问题,将辨证性认知与定量性分析有机结合,是桥梁景观综合评价的一种新方法.In view of uncertainty and complexity in the process of bridge landscape assessment, based on set pair analysis （SPA） theory, identity -discrepancy -contrary （IDC） connection degree formula which can embody certainties and uncertainties of the assessment system is introduced and set pair analysis model （SPAM） is established in bridge landscape assessment. The meaning of SPA applied to bridge landscape as- sessment in two levels is fully analyzed. All indexes can be summarized in five - member connection number. Analytic hierarchy process （AHP） is applied to calculate the weighing values in order that the artistic degree of the bridge can be calculated from the objective and subjective evaluations. As an example, Hulu fiver bridge is assessed with SPAM. The results show that： from the whole system, the artistic degree of the bridge is fine; from the subsystem, bridge esthetics, modeling and environment coordination are better than others. The results express the artistic degree of the bridge on different levels and different aspects. SPAM combines qualitative description with quantitative analysis and takes full advantage of uncertainty. It is a new model for the bridge landscape assessment.
