摘　　要：在对塔西南和田南部地区晚石炭世－早二叠世各层段的岩性、沉积构造、古生物、元素地球化学等沉积相标志综合分析的基础上，开展了沉积环境研究。将和田南部地区晚石炭世－早二叠世划分为晚石炭世－早二叠世早期、早二叠世晚期两个沉积时期，并建立了相应的沉积相模式，以此为基础，对塔西南和田南部地区石炭－二叠系的沉积演化史进行了分析。： Depositional environment study has been conducted based on comprehensive analysis for each formation of Late Carboniferous－Early Permian in southern Hetian area of southwest Tarim basin， including their lithology， sedimentary structure， paleobiology， element geochemistry and other sedimentary facies markers． The Late Carboniferous－Early Permian may be divided into two depositional periods， namely， the early subperiod and late subperiod， with their related sedimentary patterns． Then， on such basis， the evolutionary history of Carboniferous-Permian sediments in that area has been analyzed．
