摘　　要：采用典型生境抽样法,首次对江苏省大丰麋鹿国家级自然保护区开展昆虫物种调查,对该保护区昆虫群落多样性、区系组成、多样性空间分布格局和昆虫-植被群落组成关系等内容进行研究。结果显示:(1)保护区共有昆虫11目101科233种,其中鳞翅目(Lepidoptera,68种,占比29.18%)、鞘翅目(Coleoptera,47种,占比20.17%)、半翅目(Homoptera,44种,占比18.88%)、直翅目(Orthoptera,20种,占比8.58%)和膜翅目(Hymenoptera,20种,占比8.58%)物种较多,为主要群落构成种,其余类群累计34种,占比14.60%;(2)保护区昆虫区系与盐城市在动物地理区划中情况相似,以东洋-古北共有种为主,东洋种较古北种略占优势,即东洋-古北共有种占比为69.23%,东洋种占比为20.71%,古北种占比为10.06%;(3)保护区昆虫多样性空间分布格局呈现由内陆向沿海,由实验区向核心区逐渐降低的趋势,实验区昆虫多样性最高,核心区昆虫多样性最低;(4)昆虫群落结构受植被群落结构影响,5种不同植被群落中,乔木群落和其他植被群落下的昆虫种群结构存在差异,而其他植被群落下昆虫种群结构,又可依据草地生境和滩涂生境的不同植被组成进一步区分。The typical habitat sampling method was employed to investigate the insect species inhabiting the Jiangsu Dafeng Milu National Nature Reserve for the first time.And the diversity of the insect community,the spatial distribution pattern of diversity,and the relationship between insect-vegetation community compositions within the reserve were further studied.Results indicated that the reserve was inhabited with 233 insect species,101 families,11 orders.Lepidoptera(29.18%),Coleoptera(20.17%),Homoptera(18.88%),Orthoptera(8.58%)and Hymenoptera(8.58%)were the main communities with the remaining taxa in the proportion of 14.60%.Similar to that of Yancheng in the zoogeographic division,the reserve′s insect fauna was featured of dominant Oriental-Paleonorthern species(69.23%),with Oriental species accounting for 20.71%,and Palaearctic species for 10.06%.Our findings also revealed that insect diversity within the protected areas exhibited a trend of gradual decrease both from inland to coastal and from experimental to core areas.Furthermore,the insect community structure was influenced by the vegetation community structure.Among the five different vegetation communities studied,the arbor community and the other vegetation communities had different insect population structures while the other vegetation communities could be distinguished based on the different vegetation compositions of grassland habitat and tidal beach habitat.
