摘要
本文详细分析了奉贤县海岸岸滩近十年来的冲淤特征，着重讨论了潮流、波浪和沿岸泥沙运移对岸滩演变的影响。本区岸滩纵向上由东向西存在着明显的波状变化特征，在横向冲淤变幅上以低潮滩至水下斜坡上部最为明显；相对稳定的沿岸潮流和波浪作用强度是岸滩稳定的动力保证，沿岸泥沙供应量的变化则是局部岸滩冲淤变化的关键所在。基于岸滩存在不同性质的冲淤特性，在岸滩资源开发上应采取不同的措施。
This paper studies the erosion characteristics of tidal flats in Fengxian area during the last ten yeas and the development of mud flats affected by tide currents, waves and sediments near shore in detail. The results show that the mud flats is obviously wave characteristics in plane, the erosion variation from low tidal flats to the top of the slope under water is great in cross section, the relative stable tide currents and wave strength keep the mud flats stableness in dynamic, and the key of the flat erosion variation in part is the changes of the amount of sediment near shore. On the basis of the different erosion types of mud flats, the different methods should be taken in exploit resources of mud flats.
