黟县金钱松天然林的调查研究

摘要

对分布于安徽省黟县泗溪乡较大面积的金钱松天然林进行了调查研究，结果表明，金钱松天然分布区条件优越，地理区系成分复杂。分布格局呈群聚型，林分结构层次分明。前期生长缓慢，以后逐渐加快并有较长的旺盛生长期。天然更新较差。%Investigation was made on the natural forest of Pesudolarix amabilis in Yixian. The results showed that, in its distribution area,natural conditions were fine and floral elements were complex. Its distribution pattern was agregative and the stand structure had distinct levels. In early stage, it grows slowly and then its growth becomes increasingly fast. Its natural regeneration ability was rather weak.
