摘要：

A methodological study in mapping vegetation variables is presented. The method, which is related to trend surface analysis, is based on polynomial regression and is used in this paper to describe the spatial pattern of a weed community in a corn field. In a field experiment carried out in Rennes (Brittany, France), the weed flora was dominated by three species (Polygonum persicaria, Chenopodium album and Solanum nigrum). For the first two species, the mapping analysis shows a spatial gradient while for Solanum nigrum, patches were found throughout the sampling area.
