乌溪江国家湿地公园昆虫多样性分析

为了解乌溪江国家湿地公园内不同生境昆虫多样性的差异并为制定湿地保护政策提供科学依据,对选取的10种不同生境进行生物多样性调查。共采集鉴定昆虫16目138科454种,通过对昆虫进行生物多样性分析,结果表明:(1)各生境物种多样性由大到小依次为杨梅林(4.56)>厚朴(4.09)>溪边灌木(3.61)>混交林(3.60)>马尾松(3.57)>柑橘林(3.54)>油茶(3.08)>板栗林(2.94)>竹林(2.22)>河边滩涂(1.76);(2)优势度指数和多样性指数最大的是鳞翅目,均匀度最大的是鞘翅目;(3)与邻近自然保护区的比较发现,群落稳定性和环境质量关系为龙王山>天目山>凤阳山>乌溪江,均匀程度大小为天目山>乌溪江>龙王山>凤阳山;同时还列举了乌溪江的昆虫资源。

Preliminary Studies on Insects Diversity in the Wuxijiang National Wetland Park

In order to understand the insects diversity in the Wuxijiang river national forest park and provide scientific basis to make the wetland protection policy,10 different habitats were selected for biodiversity survey.The investigation found that there are 16 orders and 138 families of 454 species,the biodiversity analysis was carried out.The results showed that:(1) The habitat species diversity from high to low as follow: red bayberry forest(4.56)> cortex mangnoliae officinalis forest(4.09)>streamside shrubs(3.61) > mixed forest(3.60)>Pinus masoniana(3.57)>Citrus reticulata forest(3.54)>Camellia oleifera(3.08)> chestnut forest(2.94)>bamboo forest(2.22)>river tidal(1.78);(2) The lepidoptera had biggest Simpson index and diversity index,coleoptera had biggest evenness index;(3) Comparing with surrounding nature reserve,community stability and environmental quality relationship was that Wuxijiang River >Tianmu Mountain> Dragon King Mountain > Fengyang Mountain,degree of uniformity was that Tianmu Mountain> Wuxijiang River > Dragon King Mountain > Fengyang Mountain.The insect resource in Wuxijiang was also listed.
