摘要Abstract.在维龙加国家公园（扎伊尔）进行的一次区域调查（1978-1982年）导致在航空照片和实地工作的帮助下，按照形态土壤学方法绘制了土地系统图。利用陆地卫星专题制图仪数据（1987年现场）的分类技术，使我们能够评估的可探测性的形态土壤的限制。统计聚类的无监督分类没有得到结果，这是很容易解释的形态土壤和植被单位。监督分类更好地控制了类别的归属。根据地面资料，分析了土壤地貌单元相对区别的原因。
Abstract Abstract. A regional survey (1978-1982) in the Virunga National Park (Zaire) led to the mapping of land systems with the help of aerial photographs and fieldwork, following the morphopedological approach. The use of classification techniques on Landsat Thematic Mapper data (1987 scene) enabled us to assess the detectability of the morphopedological limits. The statistical clustering by an unsupervised classification did not give results which were readily interpretable in terms of morphopedological and vegetation units. A supervised classification gave better control in the attribution of the classes. The reasons for the relative discrimination of the morphopedological units are analysed on the basis of ground information.
