摘要
通过研究分析得到:岩桂造林地宜选在海拔500-950 m的石灰岩发育而成的土壤中造林,土层厚度在大于45 cm,坡向选择半荫、半阳坡;应用多元回归方法建立了岩桂生长指标与立地因子间的优化回归模型。
Normal site conditions of Cinnamomum petrophilum N. Chao had been studied on topography, soil type and depth. The results showed that lime soil of 500-900 m high, soil depth over 45cm, half-shade or half-sunshineaspect of slope were very agreeable site conditions for Cinnamomum petrophilum N. Chao. An optimized regression model between growth indicators and site factors was formed by multiple regression method,
