摘要

在过去几十年中,智利政府不断推动私人公路的建设,以提高全国货物和人员运输的效率。通过这种方式,出现了重型道路基础设施、景观破碎化、濒危动物栖息地的丧失、视觉质量的丧失以及生物多样性斑块的减少。尽管如此,在智利高速公路的某些区域,仍可以部分看到一些绿色植物——本地和引进的动植物、自然元素、颜色、线条、图案等。特别是,本文重点介绍了连接拉各斯地区蒙特港和帕尔瓜市的主要路线。这项定性研究的目的有三个。首先,通过在Pargua公路(Alto Bonito地区)路边的实地调查,使用改编自Tveit等人的属性量表,测量主要景观属性和视觉尺度特征。(2007)。其次,通过环境调查(植物社会学分析)来测量植被类型。第三,从养护和人为干预的角度来衡量公路的管理程度。由于垃圾填埋场和立交桥等人为干预的集中存在,路边几乎看不到荒野和自然。在实地调查中,从多个角度检查了视觉尺度。在道路的东南侧,Las Canchas地区被高大的树木、房屋和工业所覆盖,阻碍了周围自然景观的景观。在道路的右侧,可以看到卡尔布科火山和奥索尔诺火山的清晰天际线。最后,路线特许公司对这类景观的视觉景观的任何高质量管理都是随机进行的。然而,植被表面本身已经找到了一种保护土地免受侵蚀和荒漠化的方法。

Visual scale and Naturalness of Roadside Vegetation Landscape. An exploratory study at Pargua Highway, Puerto Montt – Chile
Over the last few decades, the Chilean Government has constantly promoted the construction of private highways in order to increase the effectiveness in terms of transportation of goods and people all along the country. In this way, heavy road infrastructures, landscape fragmentation, loss of endangered animals’ habitat, loss of visual quality, and a decrease of biodiversity patches have emerged. Despite this, some greenery – native and introduced flora/fauna, natural elements, colors, lines, patterns, among others- can be partly seen in certain areas of Chilean highways. In particular, this paper focuses on the main route connecting Puerto Montt and Pargua cities in Los Lagos region.The objectives of this qualitative research are threefold. Firstly, to measure main Landscape attributes and Visual scale characteristics through a fieldwork by the roadside of Pargua highway (Alto Bonito Area) using a scale of attributes adapted from Tveit et al. (2007). Secondly, to measure the type of vegetation through an environmental inventory (phytosociological analysis). Thirdly, to measure the degree of management of the highway considering its maintenance and human intervention.Wilderness and Naturalness are scarcely observed on the roadside due to a concentrated presence of human interventions such as landfills and overpasses. The visual scale is checked in fieldwork from several scopes. On the southeast side of the road, Las Canchas Area is covered by high trees, houses, and industries which hinder the view of the natural surrounding landscape. On the right side of the road, it presents a clear skyline of Calbuco and Osorno volcanoes. Finally, any management of high quality of the visual scenery of this type of landscape from the route concessionaire is is randomly done. However, the vegetation surface itself has been working out a way to protect the land from erosion and desertification.

期刊介绍: Landscape Online focuses on studies dealing with landscape research. The subject matter deals with any scientific, educational or applied aspect of processes, dynamics, indicators, controllers and visions related to landscapes. Furthermore, Landscape Online emphasizes the coupling of societal and natural systems, not only the involvement of human impact on landscape systems but also human perception of the landscape, its values and the evaluation of landscapes. Moreover, articles are appropriate that deal with landscape theory, system approaches and conceptual models of landscape, both their improvement and their discussion. Papers may be undisciplinary or multidisciplinary but have interdisciplinary or transdisciplinary appeal. All kinds of articles or parts of it must not be published beforehand in another journal
