利用马氏网评估老港固废物综合利用基地防护林节肢动物群落结构及多样性

Community Structure and Diversity of Arthropod in Shelterbelt of Laogang ComprehensiveUtilization Base of Solid Waste

    摘要
  • 摘要: 2018 年4－11 月，采用马氏网诱集法对上海市浦东新区的老港固废物综合利用基地防护林节肢动物多样性进行调查，并运用Simpson 优势度指数、Shannon-Wiener 多样性指数、均匀度指数、丰富度指数对不同功能团亚群落进行统计分析。结果表明，共采集到昆虫15 599 头，分属于3 纲17 目133 科，其中姬蜂科Ichneumqnidae 数量最多，为2 515 头，占所有昆虫种群的16.12%；不同功能团节肢动物群落的Shannon-Wiener 多样性指数排序为：总群落＞害虫亚群落＞中性昆虫亚群落＞寄生性昆虫亚群落＞捕食性天敌亚群落；害虫亚群落的Simpson 优势度指数、丰富度指数和Shannon-Wiener 多样性指数均高于天敌亚群落。以上研究结果说明该区域的天敌群落结构可能不如害虫亚群落稳定，因此，在日常养护中应注意对该区域天敌昆虫进行保护。

     

    Abstract: Arthropods were trapped in the Shelterbelt of Laogang Comprehensive Utilization Base for Solid Waste, Shanghai by the method ofMarkov network trapping from April to November 2018. Analysis were made on trapped arthropod by Shannon-Wiener index, Simpson index,evenness index and richness index in the terms of sub communities of different functional groups. The results showed that there were 15 599 insectswere collected, belonging to 133 families, 17 orders and 3 classes. Among them, Ichneumonidae had the most number of 2515, accounting for 16.12%of the total trapped insects. Shannon-Weiner index of arthropod community by different functional groups was ordered by total vommunity > pest subcommunity > neutral insect sub community > parasitic insect sub community > predatory natural enemy sub community. The dominance index,richness index and Shannon-Weiner index of the pest sub community was higher than that of natural enemy sub community, indicating that thestructure of latter was not stable as the pest sub community’s.
