乡村景观设计方案评价与优化研究

在对影响乡村景观设计方案各项因素进行综合分析的基础上,运用AHP-模糊综合评价法构造了乡村景观设计方案评价模型。首先建构了"目标层-指标层次结构",采用专家打分法建立判断矩阵,计算出相对权重,并通过两级的模糊综合评价,然后确定出每个设计方案的各因素分值和综合评价分值,作为乡村景观设计方案评价和优化的理论依据。以福建省某乡村景观设计为研究对象,对此实例的四个设计方案进行了评价验证和优化研究,结果表明,采用AHP-模糊综合评价法对乡村景观设计方案进行评价与分析是客观公正、可行有效的,根据综合评价最高分值优选出来的方案明显优于其他设计方案,并能从各因素的分值对比中得到良好的优化建议。

Rural Landscape Design Programs: Evaluation and Optimization

On the basis of a comprehensive analysis of the factors that affect the rural landscape design an evaluation model of the rural landscape design program is constructed with the help of the AHP-fuzzy comprehensive evaluation method.According to this model the target layer-indicator hierarchy is constructed,the judgment matrix is established with the expert evaluation method,the relative weights are calculated,and then the factor score and comprehensive evaluation score of each design program are determined by means of the two-grade fuzzy comprehensive evaluation,which are employed as the theoretical basis of the rural landscape design program evaluation and optimization.The landscape design for a village in Fujian province is taken as research object and four different design programs made for the same village are evaluated,examined and optimized as research contents.The results show that the AHP-fuzzy comprehensive evaluation method is objective,feasible and effective.And the design program selected according to the highest comprehensive score is obviously superior to the other design programs and fine suggestions on optimization can be made according to the score comparison between factors.
