辽东地区日本落叶松立地分类和立地质量研究

摘要

通过对辽东地区日本落叶松林的调查,利用数量化理论I确定了辽东地区日本落叶松生长发育的主导环境因子为海拔、土层厚度和坡向,并构建了辽宁省东部地区日本落叶松立地质量评价模型,检验结果表明达到了精度要求.利用这一模型可对辽宁省东部地区日本落叶松立地质量进行数量化评价.%Investigation was carried out in Larix kaempferi growing in eastern Liaoning Province, China.the main factors affecting the growth of were analyzed by quantitative theory Ⅰ. It was found that the main factors were altitude, soil depth and slope direction, respectively. A model to evaluate the site quality of L. kaempferi in this region was established. The result of examination of the model indicated that the it met the precision requirements.
