寒温带兴安落叶松林天然更新与抚育经营研究

STUDY ON NATURAL REGENERATION AND TENDING MANAGEMENT OF LARIX GMELINII FORESTIN COLD-TEMPERATE ZONE

文章对兴安落叶松林皆伐更新林、渐伐更新林及原始林天然更新特征进行分析。分析结果表明,3种森林类型的天然更新数量及高度依次为渐伐更新林>皆伐更新林>原始林;3种森林类型天然更新分布格局均为聚集分布,但是聚集强度存在差异,聚集强度依次为原始林>渐伐更新林>皆伐更新林。在此基础上提出兴安落叶松林抚育经营措施建议。

Abstract： In this paper,we studied the natural regeneration characteristic of the original forest,the successive cutting forest and the clear cutting forest in Cold-temperate zone Larix gmelinii forest.The results show that natural regeneration quantity and height of three kinds forest types were the successive cutting forest the clear cutting forest the original forest.The natural regeneration distribution patterns of the three kinds forest types were aggregation distribution,the aggregation intensity were the original forest the successive cutting forest the successive cutting forest the clear cutting forest.Based on this result,we studied the tending management measures of three kinds of Larix gmelinii forest.
