Psychometrical Evaluation on Landscape of Mined-out Quarry Reclaimed by Revegetating.

Landscape destruction caused by open-cut mining makes an impact on the environmental issue. Landscape evaluation of mined-out quarry becomes necessary from the view point of environmental protection. In this study, we investigated on landscape of mined-out quarry that was reclaimed by revegetating. Three kinds of revegetation, namely herbaceous planting, woody planting and herbaceous + woody planting, were simulated using a color image processing technology with a personal computer. Two psychometrical evaluation tests, rating-scale method and semantic differential method, were conducted using color photomontages as variable stimulus.In the quantitative analysis by a rating-scale method, it became clear for the landscape reclamation of mined-out quarry that herbaceous planting was better than woody planting when it was seen at a short distance, and woody planting was better than herbaceous planting when it was seen at a long distance. In the factor analysis by a semantic differential method, it became clear that beauty and texture of revegetation were important factors to estimate the landscape evaluation of mined-out quarry.
