| 摘 要： | 列举了中侏罗统九龙山组水生昆虫9目28科52属70种,冀北、辽西义县组水生昆虫9目31科47属53种,以及伴生动植物.这些水生昆虫很可能不是自然死亡,而是突发性事件导致的突然死亡,化石为原地埋藏,没有经过搬运.根据统计的化石名录,初步建立了两时代的水生生态系统结构图,并恢复了它们所代表的生态环境.通过对比发现,中侏罗统九龙山组水生昆虫的物种多样性大于冀北、辽西义县组,中侏罗统九龙山组可能处于群落发展早期,生态系统相对不稳定,而冀北、辽西义县组处于群落发展的稳定时期,生态系统趋于成熟.两时代整体上都为温暖湿润的气候环境,但同时存在干旱.半干旱的小气候环境,且都分布有低地湖?自、溪流和沼泽等,这些水体都为低能水体环境.此外,都有高山存在,但这些水体环境在两时代存在差异,中侏罗统九龙山组水体相对较浅,水体面积相对较小,而冀北、辽西义县组水体相对较深,水体面积相对较大.

| Abstract: | Aquatic insects, representing 9 Orders, 28 families, 52 genera, and 70 species from the Middle Jurassic of the Jiulongshan Formation, 9 Orders, 31 families, 47 genera, and 53 species of the Yixian Formation in Northern Hebei and Western Liaoning, and their associated plants and other animals are enumerated here. These aquatic insects may die due to environmental changes or other natural disaster. These fossils were buried in situ, without removal. Hypothetical structures of ecosystems are preliminarily esta... |
