【摘要】 路网结构是城市群公路交通联系在空间上的反映,为了解析公路网与区域空间结构的互动关系,在提出城市群公路网结构适应性评价的基本内涵的基础上,从规模结构、功能结构、等级层次结构、布局结构、发展趋势等5方面设计了城市群公路网结构适应性评价指标;为了提高评价的精度,运用层次分析法确定指标权重,并将其与灰色关联度法相结合,构建了灰色欧几里德加权平均关联度评价模型;最后以关中城市群为例,对模型进行验证分析,表明了该方法的科学性与合理性。更多还原

【Abstract】 The highway network is the reflection on the space of the urban group highway traffic connection.In order to analyzes the interrelation of the highway network with the areal space structure,the article puts forward the basic intension of the suitability evaluation of the urban group highway network structure,and designs the suitability evaluation indexes of urban group highway network from five aspects of scale structure,functional structure,gradation structure,layout structure and development trend.In order to enhance the evaluation correction,the gradation analysis method is used to determine the index weight.The combination of the index weight with grey relational analysis builds the grey Euclid weighted average relational evaluation model.The article proves and analyzes the model by the example of Guanzhong urban group,makes clear the scientificity and rationality of this method.更多还原
