摘　　要：通过样地调查,对内蒙古大兴安岭北部兴安落叶松3种森林类型(原始林、渐伐林、皆伐更新林)的林分空间分布格局进行了研究。结果表明:3种林分的分布格局均为聚集分布,但聚集程度存在差异,聚集强度依次为皆伐更新林>原始林>渐伐林。并提出了兴安落叶松合理经营管理的建议。Based on the field investigation of selectd sample plots a study on the spatial distribution pattern of 3 types of forests （primitive forest, successive cutting forest and clear cutting forest） of Larix gmelinii was conducted in north Daxing＇ anling in Inner Mongolia. The results demonstrated that the distribution pattern of 3 typs of forests were all in cluster distribution, but they are different in the extent. The intensity of the clear cutting forest is the biggest, primitive forest is intermidiate and successive cutting forest is the smallest. According to the results of the study, some suggestions about management of Larix gmelinii were put forward.
