长江中下游杨树抑螺防病林昆虫多样性的初步研究
|
摘要
对安庆市南埂林场长江沿岸杨树抑螺防病林3年生、8年生和20年生林地上空间昆虫群落的种群组成和多样性进行了调查。结果表明,在3种不同林龄林分之间,地上空间昆虫种群组成的差异表现为,在目一级分类单元组成上,3种不同林龄林分具有很高的共性,在科和种的单元上,不同林龄林分之间的差异大小依次为:3年生与20年生林分之间>3年生与8年生林分之间>8年生与20年生林分之间。随着林分林龄的增加,林内地上空间昆虫丰富度指数、Shannon-Wiener指数明显降低。不同林龄林分地上空间昆虫种群的均匀度指数与林分林龄无明显的相关性,其中20年生林分昆虫种群的均匀度指数显著低于8年生和3年生的林分,而8年生和3年生林分之间没有显著差异。
The composition and the diversity of insect community were investigated in planted poplar forests respectively at 3, 8 and 20 years of age on the beach of Yangtze River in Nangeng Forest Farm in Anqing city. Results indicated that among the different ages the composition of insect community appeared to be common at order level, while at species and families levels the differences between age pairs were: 3 and 20 years > 3 and 8 years > 8 and 20 years. With increase of age of the poplar forests, the species richness index and the Shannon-Wiener diversity index of insects within the forests reduced obviously. There was no significant correlation between the evenness index of insect community and ages of poplar forests. However, the evenness index of insect community was significantly smaller at 20 years than at 8 and 3 years, and no significant difference was found between 8 and 3 years.
