摘　　要：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。Based on the publications reported, fossil insects of 18 orders 113 families 240 genera 350 species with associated animals and plants of Yanliao Biota from Middle Jurassic in northern China are enumerated. Structure of ecosystem is preliminarily established by analysing their biological and ecological characteristics, and their environmental settings are reconstructed. The structure shows that the ecosystem was relatively unstable and may be in the early stage of the community. Overall, the climate of this region at the time of disposition was warm and humid, while there was seasonal arid and semi-arid climate in some micro-environments;there were plenty of lakes and swamps, in the vicinity of which there were alpines and mountain streams. The soil was nutrient and moist enough for a variety of plants, insects and invertebrates to survive.
