潮滩沉积 meaning in English
subtidal deposit
tidal flat deposit
Examples
- In this field observation we also find an important fact that , even during storm surge period , high tidal flat can still be in sedimentation in some place , no erosion occurred . to tell the typhoon storm surges from cold wave storm surges , 12 monthly sedimentary samples are collected from the modern tidal flat surface at dafeng , jiangsu . palynological analysis of these samples indicates that the seasonal palynological features of the tidal flat sediment are very obvious and some palynological indexes , such as taxon percentage of arboreal , herbaceous pollen and spore , are good indicators to tell the seasonality of the tidal flat deposits
为区分风暴潮沉积是由台风引致还是由寒流或冷锋引致，对长期处于淤积状态的江苏中部大丰县斗龙港附近潮滩，采集了一年中每月小潮期间滩面表层泥样，并在启东茅家港滩面分别采集了6月、 9月与12月的表层泥样，在实验室中，对这些样品进行孢粉等分析，认为在以粉砂、泥为主的潮滩沉积中，孢粉种类百分比，尤其是木本种类占孢粉总种类的百分比是判别季节性潮滩的重要指标，通过启东茅家港工程建设区淤积状况的观测记录对这一判别指标进行了验证。 - The field observation of the sediments of storm surge produced by no . 11 typhoon in 1997 shows that sedimentation rate of storm surge sediments are greater than that of normal astronomical tide sediments , and the grain size shows relative coarse with poor sorting . vertical sequences of the storm sediment show parallel bedding and overlapped by hummock bedding . these characteristics provide good basis for building the index of storm surge deposit
通过对梁垛河闸9711号台风的现场观测并结合目前已有的风暴潮沉积的研究，分析了风暴潮沉积在构造和结构上的特点，从而建立了正常潮滩沉积中风暴潮沉积的识别标志，同时在野外观测中还发现即使在风暴潮期间，高潮滩上部仍存在只有淤积没有侵蚀的地带。
