研究区内二叠系—三叠系生物化石较丰富,门类有腕足类、蜓类、珊瑚、菊石、牙形石、双壳类及有孔虫等。这些生物门类明显受沉积环境控制。对研究区内中二叠统—中三叠统的古生物化石进行了详细的分析和埋藏特征研究,根据生物化石在时间与空间上的组合特征,将研究区中二叠统—中三叠统生物群划分为17个生物群落,并论述了各群落的组成、结构和环境特征。研究表明,不同生态类型的群落其分布的地理位置有一定差异,主要体现在以下2个大的区块,即分别分布于研究区的主体区块和其边缘区块,前者以底栖固着型为特征,后者以游泳型及底栖游移型为特征。根据化石群落与沉积特征的组合情况,识别出6种类型的生物相,并总结了其生物相模式,阐述了各生物相中的生物类别、生态类型、典型群落以及对应的沉积相等特征。化石群落的划分和分析对于四川盆地二叠纪—三叠纪的古环境、古地理及其演化的研究具有一定的意义,生物相的研究对于研究区古生物地理学和古板块构造的恢复具有一定的意义。

The research area is located in the western part of Sichuan basin as a Yangtze ecotope of Cathaysian Tethyan area. It is dominated by benthic fauna, including brachiopods, Fusulinids, corals, bivalves, foraminifers, ammonites, bryozoans,Crinoids and pleopods which are less common with traces of trilobites, stromatoporas, nautilus and sporopollens seen in one or two areas,which are obviously controlled by sedimentary environments and in accordance with sedimentary facies.Through the analysis of fossils and research on burial characteristics from middle PermianmiddleTriassic, based on the combination of the feature of fossils in time and space, seventeen communities are recognized, the coposition, construction and palaeoenvironment of each community are expounded. Study shows that different ecological type biocoenose are distributed in different locations, which are mainly represented by sessile benthic community in the main research area, composed of Mianzhu, Mianyang, Deyang and Santai and nektonic community in marginal areas in the research area subdivided into two parts: Areas around Guangyuan-Nanjiang-Tongjiang, located at the margins in the northeast of the research area, and areas around Wenchuan-Maoxian-Dayidafeishui situated at the western borders of the research area. According to the combination of communities with sedimentary characteristics,six kinds of biofacies have been recognized and described in the study area and biofacies pattern are established. Category,ecotype, typical community and sedimentary facies of each biofacies are elucidated in this paper. The subdivision and analysis of community are meaningful for the studies of paleoenvironment ,paleogeography and their evolutions,The research of biaofacies is important for the recovery of paleobiogeography and paleoplate tectonic characteristics.
