基于AHP的城市生态文化景观评价体系构建

Construction of urban ecological and cultural landscape evaluation system based on AHP

在梳理评价指标构建原则和指标因素特征选取基础上,运用层次分析法(AHP),通过3个准则层和16个指标层构建城市生态文化景观评价体系,研究影响城市生态文化景观的重要因素。结果表明,准则层权重由高至低分别为自然生态U_(1)(0.4742)、人文层面U_(2)(0.3764)、社会层面U_(3)(0.1494);16个指标层按照对城市生态文化景观影响的重要程度划分为3类:重要因子、次重要因子和一般因子,其中,对城市生态文化景观影响最大的重要因子分别为山水格局U_(12)(0.2090)、生态化设计U_(14)(0.1297)、地域文化U_(23)(0.1098)、气候条件U_(11)(0.1041)。针对影响最大的重要因子,提出加强城市与自然山水的融合与统一、低碳引领下突出生态化设计的现代城市景观、城市景观中地域文化的创新发展、巧妙营造适宜的小气候环境等对策建议。

On the basis of sorting out the principles of evaluation index construction and the selection of index factor characteristics,AHP method is used to construct the evaluation idex through 3 criterion layers and 16 index layers.The important factors that affect the urban ecological and cultural landscape are studied.The results show that the weight of the criterion layer from high to low is natural ecology U_(1)(0.4742),humanistic layer U_(2)(0.3764),and social layer U_(3)(0.1494).The 16 index layers can be divided into three categories according to the improtance of their impact on urban ecological and cultural landscape:important factors,secondary important factors and general factors,among which the important factors that have the greatest impact on the urban ecological and cultural landscape are landscape pattern U_(12)(0.2090),ecological design U_(14)(0.1297),regional culture U_(23)(0.1098),climate Condition U_(11)(0.1041).Aiming at the important factors with the greatest impact,this paper puts forward some countermeasures and suggestions,such as strengthening the integration and unification of the city and the natural landscape,highlighting the ecologically designed modern urban landscape under the guidance of low carbon,innovative development of regional culture in the urban landscape,and ingeniously creating a suitable microclimate environment.
