摘要：断面积模型是全林模型系统中最重要的模型。本文应用南方５省（区）杉木、北方３省长白落叶松标准地，分别建立了１０组断面积模型，进行比较。结果表明，杉木按立地区建模时，虽然优势高生长过程相似，但断面积生长过程却不同，不能使用同一模型参数。杉木按产区建模时，虽属同区同带，断面积生长过程差异仍很大，因此杉木产区也不是建模的依据。东北３省长白落叶松建模结果表明，各省优势高和断面积生长过程接近，模型参数差异不大。
The basal area growth model is the most important one in the integrated stand growth model. This paper using sample plot data of Chinese fir ( Cunninghamia lanceolata ) stands from five provinces in the south of China and Larix olgensis stands from three provinces in the north of China establishes ten basal area growth models of the two species separately and the parameter adaptability among the provinces or regions are compared.The result show that the process of Chinese fir basal area growth are different between site regions where the process of dominant tree growth are similar or the planting areas even though in the same zone and in the same region, the parameters of the basal area growth model are different,so the site regions or planting areas can not be the criterion to establish different basal area growth models. The processes of the L.olgensis basal area growth are similar and there is no significant difference between the provinces for the parameters of the basal area growth model.
