1.基于过程的模型SIMFORG，基于管道理论，苏格兰松参数化在六个地点沿着在欧洲的南北梯度。Berninger等人（1995）提出，叶质量与茎横截面积的比值是潜在蒸散量的函数。不同地点对树干的分配不同，从而影响了树干的产量。净初级生产力的变化和管道模型参数的差异是造成这些差异的原因。实测数据与模拟数据吻合较好.正如气候变化senarios所预测的那样，初级生产的增加增加了对茎的分配。然而，结果是敏感的叶质量茎边材横截面积比的变化。分配的变化在北方高于南方。
1. The process-based model SIMFORG, based on the pipe theory, was parameterized for Scots Pine at six locations along a north-south gradient in Europe. The ratio of foliage mass to stem cross-sectional area was changed as a function of potential evapotranspiration as proposed by Berninger et al. (1995).2. Allocation to the stem differed between the locations and affected consequently the stemwood production. Variation in the net primary production and differences in the pipe model parameters were responsible for these differences. There was good agreement between measured and simulated data.3. Increase in primary production, as predicted by climate-change senarios, increased allocation to the stem. However, the results were sensitive to changes in the foliage mass to stem sapwood cross-sectional area ratio. The changes in allocation were higher in the north than in the south.
