摘要
通过对沂蒙工程造林区内各立地因子的分析，共组成６０种立地单元，然后直接对各立地因子分级打分，采用动态聚类方法，对立地类型进行定量分类，全区共分５种立地类型，为造林规划和适地适树决策提供了依据。
Based on the analysis of site foctors in the research area,sixty site units were di-vided.Then,after dividing and grading the site factors,dynamic cluster was used to classify the sites quantitatively,and the whole area was divided into five site types.This has provided scientific basis for afforestation program and selection of tree species according to the site.
