Construction of Cultural Landscapes along the Ya'an-Luguhu Expressway——Discussion about Techniques of Designing Highway Cultural Landscapes

The concept of cultural landscapes was introduced,and it was proposed that the construction of highway cultural landscapes should follow the principles of "protection first,secure,integrated,suitable for actual conditions,economic,natural and ecological".In this study,relevant theories were taken to analyze the design of cultural landscapes along the Ya'an-Luguhu Expressway in Sichuan Province.Natural conditions,profound cultures and historical resources in the study area were analyzed,and the construction of its cultural landscapes was further discussed from the perspectives of properly dividing landscape spaces,determining the orientation of cultural landscapes,refining regional cultures,choosing carriers of cultural landscapes,improving cultural value of important landscape nodes by using artistic settings,applying more local materials and so on.So that helpful references could be provided for the landscape design of other expressways,and the integration of cultural landscapes and highway landscape system could be realized.

新型定性与定量融合分析的高速公路主题形象定位方法研究

全域旅游背景下,"交通+旅游"融合发展日益兴盛,高速公路主题形象定位方法研究备受关注。全域旅游的快速推进以及社交网络的全面兴起,为高速公路主题形象定位方法研究提供了海量的数据支撑。以雅康高速公路为例,提出了一种定性与定量分析融合确定高速公路主题形象定位方案的方法。首先采用竞争定位法和德尔菲法,从定性角度确定高速公路的一级、二级定位理念;其次,利用社交网络数据集,通过定量分析方法,筛选出彼此关联度较高的主题形象词汇;最后,运用编辑距离算法,对定性分析的定位理念与定量分析的高频主题形象词汇进行匹配计算,进而提出高速公路的主题形象定位方案。采用这种方法,针对雅康高速公路,提炼出"川藏云端朝圣天路"等主题形象定位方案,证明此高速公路主题形象定位方法可行有效。
