| 摘 要： | 采用解析木导向曲线法编制了辽东地区日本落叶松地位指数表。在此基础上，对落叶松地拉指数与立地因子及落叶松栽植代数的关系进行了分析，认为不同栽植代数对落叶松人工森地位指数影响差异显，落叶松连作造成立地质量下降。

| Abstract: | Site index tables regarding Japanese larch in eastern Liaoning were mapped out by using stem analysis guide curve. Accordingly, analysis of the relationship between site index and site factors with planting generations of larch was carried out. The results indicated that the effect of different planting generations on site index of larch plantations differed significantly, and continuous cropping of larch led to the degradation of site quality. |
