| 摘 要： | 闭流坳陷湖盆以发育气候层序为特征,在理想条件下,气候三级周期的变化基本符合正弦曲线;一个完整的闭流坳陷湖盆气候层序Ⅰ型层序应包括4个体系域:低水位进积楔体系域、水进体系域、高位体系域和强制水退楔体系域;同样一个完整的闭流坳陷湖盆气候层序Ⅱ型层序应包括3个体系域:水进体系域、高位体系域和强制水退边缘体系域。这些体系域在气候周期变化的曲线上有相应的位置,层序界面则位于基准面变化的最低点。

| 关 键 词： | 闭流坳陷湖盆 气候层序 强制水退体系域 基准面变化最低点 |

| Abstract: | Closed depression lacustrine basin is mainly characterized by climatic sequence.In idealistic conditions, three-grade climatic periodic changes basically conform to sine curve. Type Ⅰclimatic sequence of an integrated closed depression lacustrine basin is composed of four parasequences:LPWST,TST,HST and FRWST. Similarly, type Ⅱclimatic sequence of an integrated closed depression lacustrine basin is composed of 3 parasequences:TST,HST and FRMST. These tracts have relevant locations in curves of climatic periodic changes and sequence boundary is at the lowest point of base-level changes. |

| Keywords: | closed depression lacustrine basin climatic sequence forced regressive wedge systems tract the lowest point of base-level changes |
