直径生长潜力模型的研究

Research on latent growth models of diameter

文章运用理查德生长曲线构成的遵守加法组合和乘法组合的非线性模型 ,对日本落叶松等3个树种进行了立地质量评价的尝试。结果表明 ,在森林立地质量评价的诸多方法之中 。

In this paper, by using nonlinear models constituted with Chapman-Richards growth curves which complied with the theories of addition combinations and multiplication combinations, appraisals of site qualities of 3 tree species including Larix kaempferi and other tree species were tested. The results showed that: among the appraisal methods of forest site quality, diameter growth potential was still a practical and effective measure.
