木材管理中关注的一个主要话题是确定皆伐对边坡稳定性的影响。陡峭山坡上的森林砍伐常常导致大量大规模浪费事件的发生。地理信息系统 (GIS) 是预测大规模垃圾场位置的潜在有用工具。利用基于栅格的 GIS，可以对滑坡危险参数的数字编码地图进行叠加和建模，以生成描绘高概率滑坡区域的新地图。本调查的目的是检查基于栅格的信息系统作为预测最有可能发生浅层土壤碎片雪崩的清晰山坡位置的工具。进行了文献综述，考虑了植被、道路、降水、土壤类型、坡度和坡向，以及预测大规模土壤运动的模型。重点关注数据库方法和幻灯片预测的各个方面。
A major topic of concern in timber management is determining the impact of clear-cutting on slope stability. Deforestation treatments on steep mountain slopes have often resulted in a high frequency of major mass wasting events. The Geographic Information System (GIS) is a potentially useful tool for predicting the location of mass wasting sites. With a raster-based GIS, digitally encoded maps of slide hazard parameters can be overlayed and modeled to produce new maps depicting high probability slide areas. The present investigation has the objective to examine the raster-based information system as a tool for predicting the location of the clear-cut mountain slopes which are most likely to experience shallow soil debris avalanches. A literature overview is conducted, taking into account vegetation, roads, precipitation, soil type, slope-angle and aspect, and models predicting mass soil movements. Attention is given to a data base approach and aspects of slide prediction.
