| 摘 要： | 本文分析了黄骅潮间带的两次水准测量和地貌调查资料,结合样品作了粒度分析,得出本区潮滩的四个特征如下: 1.沉积类型简单,主要为粘土和粉砂,其含量为90％以上。 2.滩涂宽阔平坦,坡度极小,是典型的平原淤泥质海滩; 3.根据地貌和水动力特征,滩涂分为三部分:A.高潮滩的龟裂带;B.中潮滩的侵蚀滩面带;C.低潮滩的平整滩面带。 4.形成本区以上特征的控制因素有两个:一是黄河携带大量物质的影响;二是气候和潮汐波浪的作用。

| Abstract: | The data, including two levelings and a geomorphic survey and sample sizing of the tidal flat in Huanghua County, was analysed in this paper. Four characteristics of the tidal flat in this area are found as follows: 1. Its sedimentary type is simple, mainly clay and silt, whose content is over 90%. 2. The flat is both broad and plain; its slope is very small, and the shore is a typically plain muddy coast. 3. According to its geomorphic and water dynamic characteristics, this flat is divided into three sections: A. the mud crack zone of high tidal flat; B. the washout zone of middle tidal flat; and C. the plain zone of low tidal flat. 4. The formation of these characteristics is controlled by two factors: the action by the Huanghe River and the action by climate, waves and tides. |
