摘　　要：系统描述鄂尔多斯盆地西南缘乾县好畤河、耀县桃曲坡、淳化县铁瓦殿等几个奥陶纪生物礁中的珊瑚化石,包括床板珊瑚6目8属14种,8属分别为Lichenaria, Amsassia, Rhabdotetradium, Syringoporella, Cateni-pora,Yaoxianopora,Plasmoporella,Parastelliporella;皱纹珊瑚1目3属4种,3属分别为Dinophyllum,Ning-nanophyllum,Favistella。其中,Lichenaria,Amsassia和Syringoporella是乾县好畤河中奥陶统生物礁的主要造礁生物;Catenipora,Plasmoporella,Favistella是淳化县铁瓦殿上奥陶统生物礁的主要造礁生物;耀县桃曲坡中奥陶统生物礁只产少数珊瑚。In this paper the coral fossils in the Ordovician reefs in the southern edge of the Ordos Basin are described. They include 14 species referred to 8 tabulate genera as Lichenaria, Amsassia, Rhabdotetradium , Syringoporella , Cateni pora , Yaoxianopora , Plasmoporella , and Parastelliporella and 4 species referred to 3 rugosan genera as Dinophyllum, Ningnanophyllum, and Favistella. This study reveals that Lichenaria, Amsassia, Syringoporella were the main reef builders in the Middle Ordovician reef at Haoshihe, Qianxian County, Shaanxi Province. Catenipora, Plasmoporella, Favistella, occur in the breccia of the reef-front facies of the Upper Ordovician reef at Tiewadian, Chunhua County, Shaanxi Province. Yaoxianopora is a secondary reef-builder in the Middle Ordovician reef at Taoqupo, Yaoxian County, Shaanxi Province.
