| 摘 要： | 通过遥感解译、现场地质地貌调查，获得了房县盆地内及控盆边界断裂活动、河流阶地、夷平面等基础资料，并在此基础上讨论了盆地新构造运动特征。综合分析认为，盆地内断裂早第四纪有一定的活动，晚第四纪以来未见明显活动迹象；控盆断裂第四纪以来有过活动，晚第四纪活动稍强，活动性质以正断为主，表现为隆起背景下的伸展构造环境；盆地新构造活动的显著特征表现为南北差异隆升，新生代地层整体往南倾斜。

| Abstract: | Based on both remote-sensing interpretation and field survey, we obtain some data about fault activity, terrace and planation of Fangxian basin and discuss the neotectonics. The preliminary analysis indicates that the fault inside basin is active in the early Quaternary but less active in late period. The boundary fault has strong activity in the late Quaternary with normal faulting, which is charcterized by extensional tectonic environment of uplift background. The characteristic of neotectonic activity presents different uplift between north and south, and the Cenozoic stratum all dips to south. |
