摘　　要：本文以研究区三条主于研究剖面沉积微相、沉积韵律、沉积旋回及生物生态分析为基础，对研究区栖霞组的沉积环境及其演化规律进行了讨论，研究结果认为，浙江省栖霞组属于潮下低能开阔无障壁环境沉积，形成于向东南缓倾斜的碳酸盐缓坡沉积背景。Based on the sedimentary microfactes and bioecologic analysis of the Qixia formation of three sections in studied area, this paper summaries the depositional rhythms, cycles and sedimentary environment of the Qixia formation, and further analyses the characteristics of its sedimentary evolution. The results suggest that the Qixia formation was formed in a subtidal,low energy, open and non-barrier carbonate ramp belt.
