| 摘 要： | 对内蒙古自治区宁城县山头乡中侏罗世九龙山组中昆虫群落进行了分析，共鉴别出3个昆虫群落：水生昆虫群落Mesobaetis sibirica-Yanliaocorixa chinensis，土壤昆虫群落Anthoscytina longa-Palaeointinodes haifanggouensis和森林草地昆虫群落Rhipidoblattina hebeiensis-Sinoprophalangopsis reticulata。根据定性和定量相结合的方法对各个昆虫群落的物种丰度，优势度和分异度等进行了分析。结果显示化石产地当时为近岸，浅水的湖泊环境，气候温暖，潮湿。

| Abstract: | Based on abundant insects fossils collected from the Middle Jurassic Jiulongshan Formation of Ningcheng County, Inner Mongolia, 3 insect communities were recognized: the aquatic Mesobaetis sibirica-Yanliaocorixa chinensis community, the soil Anthoscytina longa-Palaeontinodes haifanggouensis community, the forest and grassland Rhipidoblattina hebeiensis-Sinoprophalangopsis reticulata community. The richness, diversity, dominance and palaeogeographical distribution of dominance species within these 3 communities were analyzed. They represent a humid and warm climate condition. Results suggested that there might be a near-shore and shallow water lacustrine environment in fossil locality. |
