摘　　要：为加强湿地生态资源监测和生物多样性保护,于2016—2021年对杭州湾湿地中的人工湿地、沿堤滩涂湿地、自然滩涂湿地和人工试验林4种不同生境中的双翅目Diptera昆虫群落多样性及其季节性特征进行调查研究。结果表明,杭州湾湿地分布有双翅目昆虫18科98种,其中数量较多的科为摇蚊科Chironomidae、蝇科Muscidae、潜蝇科Agromyzidae、水蝇科Ephydridae、花蝇科Anthomyiidae、食蚜蝇科Syrphidae、果蝇科Drosophilidae等;人工湿地和人工试验林内双翅目昆虫的个体数、Shannon-Wiener多样性指数、Margalef丰富度指数明显高于自然滩涂湿地和沿堤滩涂湿地;双翅目昆虫群落组成在不同季节变化明显,春季和夏季双翅目昆虫个体数、Margalef丰富度指数和Shannon-Wiener多样性指数最高,秋季和冬季双翅目昆虫的Margalef丰富度指数和Shannon-Wiener多样性指数较低。以上研究表明,杭州湾湿地双翅目昆虫群落多样性受植被类型、季节变化等因素影响明显。During 2016 and 2021,sample plots were established and investigated on diversity and seasonal change of Diptera in 4 different habitats of Hangzhou Bay Wetland,Zhejiang province.The results showed that there were 98 species of 18 families Diptera,among which Chironomidae,Agromyzidae,Ephydridae,Anthomyiidae,Syrphidae and Drosophilidae were abundant.The insect number,diversity and richness index of Diptera in constructed wetlands and artificial experimental forests were significantly higher than those in natural tidal flat wetland and coastal tidal flat wetlands.The insect number,richness and diversity index of Diptera were the highest in spring and summer,while the richness and diversity index were lower in autumn and winter.
