ABSTRACT

The relationship between air pollution and the visual perception of scenic areas has become an important topic for research. The public has been concerned with the visual impact of air pollution in urban areas. Haze transported from urban areas and industrial facilities has degraded the pristine air quality of remote locations as national parks and wilderness areas, and its effects on the beauty of landscapes and therefore the enjoyment of visitors are believed by some to be deleterious. The control of regional haze due to emissions from multiple sources was left for future regulations. The relationships between the perceptual indices, namely, the visual air quality index and the scenic beauty estimate, and physical parameters, such as visual range, sky chromaticity and luminance, solar zenith and scattering angles, and cloud cover, were investigated using multiple linear regression. The most signficant result of the work was the finding that the sensitivity of scenic beauty to visual range differed considerably among vistas.
