摘要
自1989年在中卫下河沿石炭系地层发现昆虫化石以来,该地区已记述昆虫化石7目22属22种.通过研究下河沿昆虫群落及其伴生化石的特征,分析昆虫古生态古环境.结果表明,该地区的昆虫以森林昆虫、水生昆虫为主,反映出以蜻蜓类有翅昆虫为主要捕食者的复杂食物网关系.推测当时该昆虫群的生活环境为近岸、温暖的潮坪泻湖环境.
Since the discovery of insect fossils in the Carboniferous strata of Zhongwei Xiaheyan in 1989,the fossils have been recorded in the area as 7 families,22 genera and 22 species.By studying the characteristics of insect community and its associated fossils from Xiaheyan,the article analyzed the paleoecological environment of insects.The results showed that the insects in this area were mainly forest and aquatic insects,reflecting the complex food network relationship by taking the Dragonflies-type winged insects as the main predators.It was speculated that the living environment of the insect group at that time was nearshore and warm tidal flat lagoon.
