摘　　要：为评价旅游公路景观协调性,通过对影响旅游公路景观协调性因素的分析,采用目标分解法初选评价指标,确定公路景观与交通安全、景观与视觉、景观与生态环境协调性3个目标层。在此基础上采用德尔菲法建立景观协调性评价指标体系;将景观协调性指标权重分为价值量权重和信息量权重2部分,在序关系分析法基础上充分利用指标值信息,综合主、客观赋权法,建立旅游公路景观协调性评价指标组合权重模型。结果表明:该模型可客观有效地确定各评价指标的权重。In order to evaluate the coordination of scenic highway,the indexes are selected based on Target Decomposition Method through analyzing the factors of scenic highway landscape coordination.Then three target systems of traffic safety,vision,environment coordination and highway landscape are set up.The constitution is optimized by using Delphi technique.The weight of evaluation index system of the harmony between landscape and environment of scenic highway consistes of value weight and information weight.The combined evaluation model,based on the deviation of a single evaluation and the combined advantages of different evaluation methods,is established to get more accurate,reasonable and comprehensive value of landscape coordination of tourism highway.The results show that the model can determine the weight of each evaluation index objectively and effectively.
