模糊数学法在高速公路景观评价中的应用

以哈大高速公路为例,介绍了研究路段的概括,并借鉴了国内外高速公路景观设计和景观评价的最新研究进展,在查阅资料、实地调查的基础上,咨询了有关专家、学者,公路司机乘客、施工人员、管理人员的意见,统计分析并筛选出主要评价指标,构建高速公路景观评价指标体系。采取基于AHP的模糊数学法进行公路景观评价,得出哈大高速公路景观评价体系各因子的模糊评分值,进而结合景观质量指标权重表,构成评判矩阵,再由所确定的权重和单因素评判矩阵,得出一级评判准则的结论向量,同理求解二级评判准则的结论向量。根据最大隶属度原则对哈大高速公路景观质量进行综合评判,认为其景观总体质量综合评价结果为"一般"等级。

Application of Fuzzy Math Method in Highway Landscape Evaluation

The paper has selected main evaluation indexes and established an evaluation system for highway landscape by taking Harbin—Daqing Highway for example,concluding the research road section,using the latest researches on domestic and foreign highway landscape design and evaluation for reference,and based on relevant materials,field surveys and opinions of experts,scholars,drivers,passengers,constructors and managers.Through the evaluation by fuzzy math method based on AHP,it has obtained the fuzzy value of each index of Harbin—Daqing Highway landscape system.Furthermore,by combining with the weights of landscape quality indexes,a judgment matrix has been constructed.Then,based on the weight and single factor judgment matrix,the conclusion vector of the first level of evaluation criteria has been obtained,and the conclusion vector of the second level of evaluation criteria obtained,similarly.In line with maximal subordinate degree,a comprehensive judgment has been conducted on landscape quality of Harbin—Daqing highway,and it is considered that its general landscape quality is of the general grade.
