不同森林植被类型蛾类群落结构及其多样性研究

The community structure and diversity study of moths at the different vegetation types in Zijin Mountain area

为揭示不同森林植被类型鳞翅目蛾类昆虫群落的结构状态和功能,评价不同植物群落的生态稳定性,于2007~2008年对紫金山主要植被类型蛾类昆虫种类、种群密度、分布及发生规律进行了调查;对不同植被类型、不同季节、整体时间动态的蛾类昆虫进行了多样性方面的分析研究。结果表明：紫金山共有蛾类13总科28科355属494种,阔叶林蛾类在属、种、个体数上均为最高,针叶林均为最低;紫金山景区的针阔混交林、针叶林及竹林由于人为因素的影响加上森林的自然演替,现处于一个演替的中间阶段,阔叶林蛾类总体较为稳定,但季节性变化明显,昆虫本身的生物学特征、气候条件、生态环境是影响蛾类群落结构及动态的主要因素;紫金山蛾类种群动态有明显的时序变化,这种变化在很大程度上与季节性的温度变化有关。

In order to reveal the insect communities in Lepidoptera moths and functional status at different types of forest,population density,distribution,the diversity and occurrence of moths was investigated and analyzed at the different vegetation types and different seasons in Zijin Mountain.The results showed that there were 13 total families,28 families,355 genera,and 494 species of moths in Zijin Mountain.The genera,species and individual number of the moths were the highest in broad-leaved forest and lowest in coniferous forests.Because of human disturbances and the natural forest succession,mixed coniferous,coniferous forest and bamboo forest in Zijin Mountain are being in an intermediate stage of succession now,moths were generally more stable in broad-leaved forest,but seasonal changed significantly.The biological characteristics,climatic conditions and ecological environment were the main factors which affected the moth community structure and dynamics.Moth population dynamics in Zijin Mountain had visible timing changes,which might be related to the seasonal temperature changes.
