根据杏园节肢动物群落物种的组成和数量,按照营养和取食关系,将群落划分为植食类、捕食类、寄生-中性类。按照系统分科的方法,将每个亚群落分成不同的功能类群,采用群落分析的多个参数研究群落的结构和动态。结果表明,杏园内共有昆虫47科59种,其中捕食性天敌有14科16种,植食性昆虫有28科37种,寄生及中性昆虫5科6种;植食类的相对丰盛度为0.98419,捕食类相对丰盛度为0.01446;对不同月份的节肢动物群落多样性和均匀性进行比较,发现多样性指数时高时低,呈现明显的波动性,其中5月份多样性指数达到最大值;均匀性与多样性表现出相同的趋势。
According to the composition and quantity of arthropod community species in apricot orchard, the community is divided into phytophagous, predatory and parasitic - neutral according to the relationship between nutrition and feeding. According to the method of systematic division, each sub-community is divided into different functional groups, and the structure and dynamics of the community are studied by using multiple parameters of community analysis. The results showed that there were 47 families and 59 species of alfalfa, including 14 families and 16 species of predatory natural enemies, 28 species of plant-eating insects, 37 species of parasitic insects and 5 families of 5 families of neutral insects. The relative abundance of plant-eating species was 0.98419, and the relative abundance of predatory species was 0.01446. Comparing the diversity and evenness of arthropod communities in different months, it was found that the diversity index was high and low and fluctuated obviously, of which the diversity index reached the maximum in May. Uniformity and diversity show the same trend.
