摘要：

A raster/quadtree geographical information system (GIS) was established For a 932 ha natural area in central Missouri. The GIS contained map layers depicting vegetative cover from 1939 to 1982, soils, topographic aspect and distance from a forest seed source. Discriminant function analysis was used to quantify and describe ecological succession on the area during this period. The calibration of discriminant functions is discussed, as are the statistical and spatial validations of (he model. It was concluded that this approach provides a useful technique to examine long-term temporal phenomena in a spatial context. © 1991 Taylor & Francis Group, LLC.
