摘要
城市街道景观评价可为街道景观的优化提升提供决策依据.以著名的旅游城市桂林市为例,基于实地调查提取研究区街道景观信息,通过分析城市街道景观特征,分级构建了以功能、生态、美学和文化4方面作为评价准则的城市街道景观综合评价体系,并分别运用层次分析法(AHP法)和熵权法,分析了桂林市5条主要旅游通道街道景观的现状,并针对分析结果对两种方法进行比较和优选.分析结果表明:权重变化对基于AHP法的街道景观评价结果影响不大,两种不同的指标赋权法得到的指标权重虽有所差异,但评价结果基本相同,即5条旅游通道街道景观质量由高到低依次是滨江路、翊武路、龙隐路、七星路和穿山路.通过比较AHP法和熵权法的城市街道景观评价结果,揭示了AHP法在城市街道景观评价中因其主观性和不确定性所产生的局限性,证明了熵权法在城市街道景观评价方面的科学性和合理性,丰富了空间多准则决策技术.
The evaluation of urban street landscape can provide a decision basis for the optimization and improvement of street landscape.Famous tourist city of Guilin,for example,street view in the study area information extraction based on field survey,through the analysis of characteristics of urban street landscape,grading is constructed with function,ecology,aesthetics,culture in four aspects as evaluation criteria of city street landscape,a comprehensive evaluation system and using the analytic hierarchy process(AHP)method and entropy weight method,and analyzes the five major tourist channel street in Guilin landscape present situation,and compares the two methods on the analysis and optimization.AHP method is based on the analysis results show that the weight change of street landscape has a little influence on the evaluation results,two different weighting method to get the index weight is differ,but the evaluation results are basically the same,namely 5 travel channel street landscape quality from high to low in turn is the Binjiang road,Yiwu Road,Longyin Road,Qixing Road and Chuanshan road.By comparing the AHP method and entropy weight method of city street landscape evaluation results,reveals that the AHP method,the limitations of subjectivity and uncertainty,proved that the entropy weight method in the aspect of urban street landscape evaluation is scientific and reasonable,enriched the spatial multi-criteria decision making technology,and in the landscape evaluation and optimization of ascension has been widely used in related field.
