In this paper, the surface and core sediment samples were collected in Xinyanggang Bay, north Jiangsu Province, and their grain size parameters i.

利用2004年1月3日在江苏盐城珍禽国家级自然保护区核心区新洋港采集到的表层和柱状沉积物样品,采用矩值法对该潮滩沉积物粒度和粒度参数进行了分析和计算,并对潮滩沉积物的水平和垂向分布特征以及不同植被对沉积物分布的影响进行了研究,结果表明:(1)自海向陆,光滩、互花米草滩、互花米草盐蒿混合滩、盐蒿滩和芦苇地5个亚带中,光滩沉积物的粒径明显较其它4个亚带处的粒径大,在接近互花米草滩时沉积物的粒径迅速变小,而互花米草滩等其它4个亚带处的沉积物粒径则变化不大。

We analyze these samples with a Cilas 940L particle size analyzer and compute the grain size parameters.

共采集样品 27 个，对其用激光粒度仪进行粒度分析，发现沉积物的粒度参数、粒度组分及其分布均具有一定的变化规律，且与滩面高程变化具有很好的相关性。

Spatial distribution characteristics of surface sediment grain-size parameters on the intertidal flat using hyperspectral remote sensing data

基于高光谱的潮间带表层沉积物粒度参数空间分布规律研究

Comparison was made of te grain-size parameters and composition of 48 sediment sample collected from this region during the coastal zone investigation were analyzed.

此外,分析长江口不同潮时采集的沉积物粒度特征说明,不同潮时的动力作用下,大潮期间的沉积物粒度参数和物质组成与中、小潮期间相应的沉积物粒度参数及物质组成有所不同,因而对长江口不同时期的沉积物作比较分析时,选择同一潮时的沉积物可能更有意义。

We analyzed grain-size compositions of terrigenous fractions in 8 core sediments from the southern Yangtze River mouth and Zhoushan Islands area,and compared the grain-size characteristics between them by using the calculated grain-size parameters.

结果表明,除舟山群岛峡道的站位(ZSC7孔)样品外,其他各站位沉积物的粒度组成和粒度参数均表现出明显的相似性;利用粒度参数间的关系,可以判定舟山群岛外侧与长江口外沉积物中的陆源碎屑来源相近。
