露天开采后造成的景观破坏给社会带来了不利的影响。本文介绍预测与评价露天开采引起景观变化的方法。随着采掘的延伸，景观的变化可用数字地形模型来摸拟，并能以图形显示在计算机屏幕上。用电子计算机图形和实际的外观图片制成的合成照片进行了评价性实验。计量心理学的两种评价方法——尺度法和选择法均已被用于从景观工程角度来观察计算开采后的露天坑所能容许的标准值。在这次实验中，选择两个采石场作为研究的例子。从评价实验结果来看，开采后的露天坑的景观变化取决于背景山的高度比和开采坡面的外现高度。开采坡面的外观高度是景观评价的一个极其重要的因素。采石场开采坡面外观高度的容许值限度约为0．037，该值相当于目视角1°，这也是一个正常人在此时能辨清所观测的物体的位置。因此，从保护景观的角度来看，外观高度0．037是开采后的露天坑允许标准值，无疑是一个定量准数。
Landscape destruction caused by open pit mining has adversely affected the society. This article describes ways to predict and evaluate landscape changes caused by open pit mining. As mining progresses, landscape changes can be simulated using digital terrain models and graphically displayed on computer screens. Evaluation experiments were conducted on synthetic photos made with computer graphics and actual appearance pictures. Two evaluation methods of measurement psychology-scale method and selection method-have all been used to observe from the landscape engineering point of view the standard values that can be calculated after the exploitation of open pit. In this experiment, two quarries were chosen as examples. Judging from the experimental results, the landscape change of the open pit after mining depends on the height ratio of the background mountain and the apparent height of the mining slope. The apparent height of a mining slope is an extremely important factor in landscape assessment. The tolerance of the height of the quarry face on the mining slope is about 0.037, which corresponds to 1 ° of the viewing angle. This is where a normal person can see the observed object at this time. Therefore, from the perspective of landscape protection, the apparent height of 0.037 is the allowable standard for the open pit after exploitation, undoubtedly a quantitative standard.
