摘要:

In this study we applied a theoretical model for determining the projection area of a Scots pine(Pinus sylvestrisL.) crown in different directions. The model is based on the assumption that the foliage elements (shoots) are randomly distributed within a symmetrical crown envelope. The model was tested using photographically measured data for three young Scots pine crowns. The compatibility between calculated and measured values was satisfactory.
