基于灯诱调查法的雄安新区昆虫群落结构及多样性研究

Study on insect community structure and diversity in Xiongan New Area based on lamp lure survey method

  • 摘要: 为深入了解雄安新区昆虫群落结构特点及其多样性,应用黑光灯诱虫法,对雄安新区3县23个乡镇的昆虫群落进行采集调查,并对其群落组成结构、不同地区群落多样性及时序动态进行分析。结果表明:共诱集到各类昆虫11目97科347种12551头,鳞翅目、鞘翅目、半翅目都比较丰富,其中鳞翅目的科数和物种数在安新县、容城县、雄县3县内均最多。安新县大王镇多样性指数和丰富度指数最高,优势度指数最低;安新县老头河镇优势度指数最高,多样性指数和丰富度指数最低;均匀度指数最高为雄县昝岗镇,最低为雄县北沙口乡。昆虫科数和个体数7月下旬达到最高峰;群落多样性指数和丰富度指数6月下旬最低,7月下旬较高,优势度指数8月上旬最高,9月上旬较低,均匀度指数在6月下旬和8月上旬波动较大,其他月份较稳定;绝对优势类群和一般优势类群时序动态的发生高峰期主要出现在7月下旬,昆虫常见种最低值主要出现在6月下旬,最高值主要出现在7月下旬。综上所述,雄安新区昆虫群落较丰富,并且具有较高稳定性。

     

    Abstract: In order to deeply understand the structural characteristics and diversity of insect communities in Xiongan New Area, Using the black light lure method, insect communities in 23 townships of 3 counties in Xiongan New Area were collected and investigated, and their community composition structure, diversity characteristics and temporal dynamics in different regions were analyzed. the results show that: A total of 12551 insects belonging to 347 species and 97 families in 11 orders were attracted, including abundant species in the orders Lepidoptera, Coleoptera, and Hemiptera. The number of families and species of lepidoptera is the largest in Anxin, Rongcheng and Xiongxian counties. The Dawang Town in Anxin County has the highest diversity index and richness index and the lowest dominance index; Laotouhe Town of Anxin County has the highest superiority index, and the diversity index and richness index are the lowest; The highest uniformity index was in Zangang Town, Xiong County, and the lowest was in Beishakou Township, Xiong County. The number of insect families and individuals peaked in late July; The community diversity index and richness index are lowest in late June and higher in late July, while the dominance index is highest in early August and lower in early September. The evenness index fluctuates greatly in late June and early August, and is relatively stable in other months; The peak period of the temporal dynamics of absolute dominant groups and general dominant groups mainly occurred in late July, The lowest value of common insect species mainly appeared in late June, and the highest value mainly appeared in late July. In summary, the insect community in Xiongan New Area is relatively rich and has high stability.
