Prediction and Evaluation of Landscape Change Caused by Land Deformation

本研究的内容分为两个部分。一种是露天开采引起的景观变化预测，另一种是露天开采复垦采石场的景观评价，利用数字地形模型模拟开采过程中的景观变化，并用线框法和多边形法在计算机图形屏幕上显示。利用彩色图像处理技术，在PC机上合成了采空区的照片。为了更逼真地呈现场景中的变化，以彩色图像为变量刺激，进行了两种心理测量学评估测试，即等级标度法和语义差异法。通过等级尺度法进行定量分析，结果表明，采空区景观复垦在近距离时草本植物优于木本植物，在远距离时木本植物优于草本植物。采用语义差异法进行了轮廓分析、因子分析、聚类分析和多维尺度分析四种分析方法。可见，恢复植被的美观和质地是评价采空场景观的重要因素。

The contents of this study was divided into two parts. One was a prediction of landscape change caused by open-cut mining, the other was a landscape evaluation of mined-out quarry reclaimed by revegetating.Landscape changes with the progression of mining were simulated by the use of digital terrain models, and that were shown on the computer graphic screen with the wire-frame method and the polygon method. Photomontages of mined-out quarry were composed by the use of color image processing technology with personal computer. It became possible to present changes in the scene more realistically.Two psychometrical evaluation tests, rating-scale method and semantic differential method, were conducted using color photomontages as variable stimulus. In the quantitative analysis with 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. Four kinds of analysis, namely profile analysis, factor analysis, cluster analysis and multidimensional scaling analysis, were conducted with semantic differential method. It became clear that beauty and texture of revegetation were important factors to estimate the landscape evaluation of minedout quarry.
