公路建设项目景观视觉影响评价的方法研究

公路建设的景观视觉影响及其保护措施,是我国公路建设中环境保护的热点问题之一。本文在国内外相关研究的基础上,以青藏公路改建工程为例,采用矩阵分析的方法,从景观美学质量评价、视觉敏感度分析、工程活动影响等景观视觉影响要素出发,划分了青藏公路沿线的景观保护级别,建立起青藏公路景观视觉影响评价方法,并以公路施工建设中具有代表性的取土场为例,结合视觉冲击强度分级,进行了相关的景观视觉影响评价。

Methods Study on Landscape and Visual Impact Assessment of Road Construction

Visual Impact Assessment and landscape protection were hot issues in the environmental protection work of highway construction in China. Taking the Qinghai-Tibet Highway Reconstruction Project as an example, this paper established a model by matrix analysis to assess the visual impact of highway project based on landscape aesthetics, visual angle, visual distance and engineering work impact. Based on this model, this paper discussed the visual impact assessment of soil-fetching work in highway project and the combination of the visual impact strength grading.
