建立了6种桉树林分茎体积产量预测模型。， E. obliqua L'Her。， E. delegatensis R. Baker。毛毛蕨史密斯，格兰迪斯希尔，梅登和杂色蕨米尔。所使用的数据集是由澳大利亚八个主要林业机构多年来收集的。它只包括在其整个生命周期中没有受到重大自然或非自然干扰的充分储存的单一林分的数据。大部分数据来自再生林，但也包括一些人工林的数据。这些数据并没有正式或完整地对这六种物种自然发生的整个地区进行抽样。在应用模型时，必须牢记这些数据限制。建立了每个树种的立地指数方程，并利用该方程建立了基于常用舒马赫模型的林分茎体积产量预测模型。然后用这些模型来比较增长率。
Summary Stand stem volume yield prediction models are presented for six eucalypt species Eucalyptus regnans F. Muell., E. obliqua L'Her., E. delegatensis R. Baker. E. pilularis Smith, E. grandis Hill ex Maiden and E. diversicolor F. Muell. The data set used was collected over many years by eight of the major forestry agencies of Australia. It included data only from fully stocked, monospecific stands which had received no major natural or unnatural disturbance throughout their life-times. The bulk of the data was collected from regrowth forest, but some data from plantation forest were also included. The data did not sample formally or fully the entire area of natural occurrence of the six species. These data limitations must be borne in mind when applying the models. A site-index equation is developed for each species and these are then used in developing the stand stem volume yield prediction models which were based on the commonly used Schumacher model. The models are then used to compare growth rates ...
