根据节肢动物群落中物种的营养和取食关系将总群落划分为天敌亚群落和非天敌亚群落(含害虫和中性昆虫),以调查到的节肢动物种类、个体数量结合各群落生态学指标分析总群落及亚群落的结构组成。共查得节肢动物55种分属47科;非天敌亚群落为总群落主要成分,相对丰盛度为0 8948,其中优势种为同翅目昆虫;天敌亚群落相对丰盛度为0 1055;优势种为蜘蛛类天敌。优势集中性和优势度分析表明非天敌亚群落 总群落 天敌亚群落;多样性分析表明天敌亚群落 总群落 非天敌亚群落。二者结果相符合,是由优势种种群数量较高造成的。
The total community was divided into natural enemies sub-community and non-natural enemy sub-communities (including pests and neutral insects) according to the relationship between the species of the arthropod community and the feeding and feeding. Based on the surveyed arthropod species, the number of individuals and ecological indicators Analysis of the total community and sub-community structure. A total of 55 species of arthropods were found, belonging to 47 families. The non-natural enemy sub-community was the main component of the total community, with a relative abundance of 0 8948, of which the dominant species was Homoptera; the relative abundance of natural enemies was 0 1055; For the spider predators. The analysis of dominant concentration and dominance showed that the natural enemies of the non-natural sub-communities were all sub-communities. The diversity analysis showed that the natural enemies of the natural enemies were non-natural sub-communities. The result of the two is consistent with the higher population of dominant species.
