福建武平帽布天然米槠林皆伐火烧后重要值和物种多样性变化规律研究．结果表明：火烧后幼树层重要值最大者为阳性树种（山乌桕Ｓａｐｉｕｍｄｉｓｃｏｌｏｒ）、灌木层重要值最大者为阳性树种（茶秆竹属一种Ｐｓｅｕｄｏｓａｓａｓｐ．），而火烧前幼树层重要值最大者（米槠Ｃａｓｔａｎｏｐｓｉｓｃａｒｌｅｓｉ）变为第２位、灌木层重要值最大者（赤楠Ｓｙｚｙｇｉｕｍｂｕｘｉｆｏｌｉｕｍ）也变为第２位；其它层次火烧前后重要值最大者基本一致，火烧后各层次物种多样性指数有所增加，其原因是由于阳性树种的侵入，使得物种数增加，总个体数也增加，同时均匀度增加，优势度下降
Study on Variation of Importance and Species Diversity of Natural Castanopsis fargesii Population after Clear Fire in. The results showed that the most important value of sapling was the positive tree species (Sapiumdiscolor), the highest value of the shrub layer was positive (Pseudosasasp.), While the value of the pre-fire sapling layer was the largest (Castanopsis carlesi) changed to No. 2, and shrub layer (Syzygiumbuxifolium) was the second highest. The other important values were the same before and after fire, and the species diversity index The increase is due to the invasion of the positive species, resulting in an increase in the number of species and an increase in the total number of individuals, with an increase in evenness and a decrease in the dominance
