笔者介绍云南宁蒗油果木地区中二叠世含筑蜓地层，地层的岩石学及古生物特征，并就各期沉积环境作一简要分析。对筑蜓类动物群进行详细研究，记述了１３属４８种。依据筑·蜓类的演化，自上而下建立５个筑蜓化石带，分别为：（５）Ｎｅｏｓｃｈｗａｇｅｒｉｎａ延限带；（４）Ｓｃｈｗａｇｅｒｉｎａｐｓｅｕｄｏｃｈｉｈｓｉ－ａｅｎｓｉｓ－Ｓｃｈｗａｇｅｒｉｎａｌｏｎｇｉｐｅｒｔｉｃａ带；（３）Ｎａｎｋｉｎｅｌａｏｒｂｉｃｕｌａｒｉａ－Ｐｉｓｏｌｉｎａｓｕｂｓｐｈａｅｒｉｃａ带；（２）Ｍｉｓ－ｅｌｉｎａｃｌａｕｄｉａｏ带；（１）Ｓｔａｆｆｅｌａｍｏｅｌｅｒａｎａ带，同时讨论筑蜓类动物群的特征，并与国内相关地层进行了对比。
The author introduces the petrologic and paleontological characteristics of the Permian stratocumulus and stratum in the Yulinmu area of Ninglang, Yunnan, and makes a brief analysis of sedimentary environment in each period. On the dragonfly fauna detailed study, account for 13 genera and 48 species. According to the evolution of the Zhufutong class, five Jufong fossil belts were established from top to bottom: (5) Neoschwagerina extension zone; (4) Schwagerinapseudochihsi-aensis-Schwagerinalongipertica zone; (3) Nankinelaorbicularia-Pisolinasubsphaerica zone; 2) Mis-elinaclaudiao belt; (1) Staffelamoelerana belt, discussing the characteristics of the Jufus fauna and comparing with the related strata in China.
