根据目前已发表的资料,统计中国北方中侏罗世燕辽生物群化石昆虫18目113科240属350种及其伴生动植物,通过对其生物学和生态学特性的分析,初步建立了中国北方中侏罗世燕辽生物群生态系统结构关系图,并恢复了它们所代表的生态环境。结构关系图显示该生态系统相对不稳定,可能处于群落发展早期。该地区整体上为温暖湿润的气候环境,同时存在季节性干旱-半干旱的小气候环境;有丰富的浅水湖泊和沼泽等水体,湖泊附近存在高山,山间有溪流;土壤营养丰富且水分比较充足,适宜多种动植物生存。
According to the published data, 350 species of fourteen genera and 113 associated genera, 18 orders, 113 families, and fossils from the Yanliao Group in the Middle Jurassic Yanliao biota in North China were collected. Based on the analysis of their biological and ecological characteristics, Jurassic Yanliao biota ecosystem structure diagram, and restore the ecological environment they represent. The structural diagram shows that the ecosystem is relatively unstable and may be at an early stage of community development. The whole area is warm and humid climate environment, meanwhile there is a seasonal arid-semi-arid microclimate environment; there are abundant water bodies such as shallow lakes and swamps; there are high mountains near the lakes and streams in the mountains; soil is rich in nutrients and water is abundant , Suitable for a variety of plants and animals to survive.
