【摘要】 针对山区高速公路景观综合评价的多目标、多层次等特点,运用多层次灰色理论的方法,对可比性方案通过综合评价选出最优方案.通过对山区高速公路景观方案评价因素指标分层及参考数据的确定,采用由两两比较优先关系矩阵建立模糊一致矩阵的方法,对各层指标相对权重系数进行了确定和检验.借助灰色关联分析,计算了山区高速公路景观方案的综合关联度,根据关联度越大排序越前的原则,确定出最优方案.更多还原

【Abstract】 When comprehensively evaluating landscapes of expressway in mountainous area, the evaluation system has those characteristics of multi-targets and multi-layers. According to those features, the multi-levels grey system is applied to the evaluation system to select the most superior scheme from the comparable plans. It determines the index delaminating and reference data of evaluation factors of expressway landscape projects in mountainous areas. Based on the fuzzy priority relation matrix, it set up the fuzzy complementary judgments to decide the relative right weight of every index in the evaluating system. The synthetically grey related degree of every plan is calculated with grey related analysis method. The biggest one is the best plan.更多还原
