| 摘 要： | 海滩地貌动力状态是海滩过程和陆海相互作用研究中的重要内容,但目前国内对北部湾强潮环境下的砂质海滩地貌与沉积的研究相对较少。对2010年3月采集的北海银滩剖面高程与沉积物变化的资料进行分析,探讨此类海滩响应外在驱动力作用的地貌动力状态特征,结果表明:1)北海银滩地貌结构简单,地貌状态属于消散型类型。2)银滩沉积物类型为砂,并以细砂、中砂为主,沉积物分选性较好;此外,沉积物中砂的百分含量和中值粒径自陆向海逐渐减小,而极细砂的百分含量则逐渐增加。3)北海银滩横向剖面沉积物可区分为后滨、滩面和内滨3个沉积单元。后滨沉积物在风的作用下以跃移质为主;滩面沉积物因波浪形成的冲流作用而具有双向运动的性质;内滨沉积物主要受控于波浪和潮流的联合驱动作用而以跃移质组分为主。

| Abstract: | Beach morphodynamic state is one of the important contents to understand beach processes and land-ocean interac-tion.Few studies on geomorphology and deposit for sandy beaches in response to strong-tidal action in China have ever been conducted.Based on the measured profile change and associated depositions of Yintan Beach in March,2010,deposition cha-racteristics of strong-tidal beach profile in response to externally-driven actions were analyzed.The results show that: 1) It is of simple geomorphologic com... |
