| 摘 要： | 根据样地调查资料，分析了西南桦人工幼林生长与立地条件的关系。结果表明：林分上层高和平均高与立地腐殖质层厚度、坡位（由山顶到山脚）呈正相关，与土壤紧实度和石含量呈负相关。通过逐步回归，建立了林分上层高、平均高与坡位、腐殖质层厚度和土壤石含量之间的方程，为西南桦人工林立地选择和立地质量评价提供了依据。

| Abstract: | On the basis of investigated materials in the plot,a relationship between height increment of Betula alnoides plantation and site conditions was analyzed with simple regression and stepwise variable selection. The results showed that the top height and mean height of the plantation increased as the increasing of slope location (from mountaintop to the valley) and the thickness of humus-layer with linear function. By the contrast, the top height and the mean height of the plantation decreased as the increasing of soil elastic and rock content with linear function. And the multiple equations were worked out in the paper, which provided a foundation for the site selection and evaluation of Betula alnoides plantation. |
