摘  要：
为研究不同土壤条件下阔叶红松林昆虫群落结构及动态的差异,对凉水自然保护区内5种不同类型土壤上阔叶红松林昆虫群落进行了系统的调查。调查共捕获昆虫3547只,分属10目41科179种,其中膜翅目和双翅目为优势类群。极点排序表明5种生境昆虫群落具有一定差异,Ⅰ生境和Ⅲ生境差异最大。各生境昆虫群落不同营养类群中,物种数最多均为植食性昆虫类群,最少均为寄生性昆虫类群。不同生境昆虫群落相对稳定性为Ⅰ>Ⅱ>Ⅳ>Ⅴ>Ⅲ。主分量分析表明,在各生境中对昆虫群落变化起着主导作用的因子具有较大差异。研究认为,5种生境中厚层典型暗棕壤阔叶红松林综合环境条件最适宜昆虫群落发生发展,薄层典型暗棕壤稳定性相对较低,建议通过适当措施,增加天敌昆虫类群丰富度,提高昆虫群落稳定性。

摘  要：
In order to study the difference of insect community structure and dynamic,a systematic investigation was carried out on the insect community in broad-leaved Korean pine forest on five types of soil in Liangshui Natural Reserve. 3547 insects were collected in the survey,belonging to 179 species,41 families and 10 orders,among which Hymenoptera and Diptera were the dominant groups. Polar ordination analysis showed that there were some differences among the five habitats and Habitat I and Habitat Ⅲ had the biggest difference. Phytophagous insect has the maximum species and parasitic insect has the minimum among insect community habitats. Relative stability of different habitats is Ⅰ > Ⅱ > Ⅳ > Ⅴ > Ⅲ. The principal components analysis showed that the dominant factors had significant differences in the five habitats. Results indicated that the broad-leaved Korean pine forest on thick dark brown soil was the most suitable for growth and development of insect community and the forest on thin dark brown soil had the relatively low stability. It was suggested that appropriate measures should be taken to increase the richness of the natural enemy insects and the stability of the insect community.
