摘要:
根据样地调查数据,对云南松人工林与天然林的群落结构进行了比较分析。结果表明:(1)天然林的物种丰富度明显高于人工林,人工林中云南松的重要值高达294.7,而天然林中伴生有较多的阔叶树种。(2)人工林中针叶树的枯落物占90%以上,而天然林中阔叶树的枯落物占40%。(3)云南松属于衰退种群,而滇油杉、黄毛青冈属于增长种群。(4)天然林中的云南松个体绝大多数树干通直,而人工林中1/4以上树干弯曲。
Abstract:
Based on the data collected from sample plots, the differences in community structure between artificial? and natural forests of Pinus yunnanensis were studied. The results were as follows. (1) There were more tree species in natural forests than those in artificial ones. And the importance value of P. yunnanensis reached 294.7 in artificial forests, but there were some broadleaf trees in natural forests. (2) The litters of coniferous trees accounted for 90% in artificial forests, but litters of broadleaf trees were 40% in natural forests. (3) The population structure of P. yunnanensis belonged to declining type, but the population structure of Keteleeria evelyniana and Cyclobalanopsis delavayi were characterized by an increasing type. (4) The overwhelming majority of individuals in natural forests were straight, but a quarter of individuals were crooked in artificial forests.
