随着桑地亚哥·得·卡姆波斯特拉朝圣之路(Santiago de Compostela)的成功申遗,以及近年来京杭大运河、丝绸之路申遗呼声的高涨,跨区域大型线性遗产正逐渐成为研究热点。本文在对文化线路和遗产廊道进行中国化的理论解读后,引入了文化廊道的理念。以西南丝绸之路(云南段)为例,在专家评价的基础上,运用地理学的方法,借助于GIS对廊道空间进行分析,提出了确定廊道范围的计算方法,并推导出文化元素"影响力半径"的计算公式;从节点、通道、域面三个方面对西南丝绸之路(云南段)的旅游空间进行了构建,并给出了廊道空间分析、构建的方法和指标体系,为西南丝绸之路旅游开发及其他文化廊道(茶马古道、京杭大运河等)的保护和开发机制研究提供了借鉴。

This paper first reviews the theories of the former, then introduces a new concept of Cultural Corridor which is suitable for China, and explains its core idea. At the base of the path's culture, Cultural Corridor has special linear cultural heritage based on its natural and cultural settings, and reflects multi-dimensional, continuous and reciprocal exchanges of goods, ideas, knowledge and values between peoples and regions over significant periods of time due to people's migration and communication. Identifying the extent is an important basic work, which can help deepen its related study. This paper aims to provide a sound method to identify the corridor's extent. Firstly, the cultural elements related to Cultural Corridor are recognized through experts' comments. Then, a formula is deduced to calculate the "affective force radius" of every element with the comments of experts. Based on the radius, the buffer zone of every element is made with the software of GIS, and then the extent of Cultural Corridor is obtained. Finally, this paper provides an index system to analyze, construct and optimize tourism spatial structure from three aspects: junction, path and domain. According to the above results, the domain of Cultural Corridor can be obtained easily.
