传统的森林土壤测绘方法耗时长，成本高。描述了一个专家系统，并将其应用于在单一花岗岩母质上形成的五个森林土壤景观单元的制图。三个专题地图被认为对影响土壤的分布很重要。第一个模型显示了9类原生桉树林的分布，第二个和第三个模型来自数字高程模型，代表坡度和土壤湿度指数结合地形位置。这些层被输入到基于栅格的地理信息系统（GIS）中，然后以几何方式共同注册到一个规则的30米网格中。根据土壤分布的知识，由经验丰富的土壤科学家量化土壤景观单元与三个数据层之间的关系，并将其作为基于规则的专家系统中的规则。从GIS中获取的主题层为专家系统提供了推断森林土壤-土地特征的数据。
Abstract Mapping forest soils using conventional methods is time consuming and expensive. An expert system is described and applied to the mapping of five forest soil-landscape units formed on a single granitoid parent material. Three thematic maps were considered important in influencing the distribution of soils. The first showed the distribution of nine classes of native eucalypt forests, and the second and third were derived from a digital elevation model and represented slope gradient and a soil wetness index combined with topographical position. These layers were input to a raster based geographical information system (GIS) and then geometrically co-registered to a regular 30 m grid. From a knowledge of soil distributions, the relationships between the soil-landscape units and the three data layers were quantified by an experienced soil scientist and used as rules in a rule based expert system. The thematic layers accessed from the GIS provided data for the expert system to infer the forest soil-lan...
