摘要

摘要: 我国河口海岸和近海区域的沉积物类型多样,粒级范围包括砾、砂、粉砂和黏土,其主体粒径范围为-4~10 φ,常规的粒度分析技术不能满足一次性完成测量的要求。以图像法作为建立粒度分析标准的测量方法,以新型激光粒度粒形分析仪为主体,以显微镜法为补充技术手段,对筛分法、吸管法和主流激光粒度仪等粒度资料进行同化处理,对主流粒度分析仪器和方法的输出结果进行转换,有助于河口海岸学与海洋沉积学对同样的粒度和粒度参数数据有统一的认识;在此基础上,对沉积物的粒度和类型所用术语进行区别,使得沉积物资料的对比有可能的"共同语言"。

Abstract: A variety of sediment types exist in estuarine and coastal environments. Sediments are generally consisted of gravels, sands, silts and clays, varying between -4φ and 10φ. It is difficult for traditional techniques of particle size analysis to fulfill the task of "one sample, one output with one measurement". Image analysis technique can be used as the standard method for particle size analysis. In this study, a new particle size and image analyzer was used, combined with microscopic method, to standardize the outputs of mainstream particle size analysis instruments, Thus, there is a possible "common language" for the standardization of sediment data obtained by different methods. On this basis, an universal usage software for the calculation of grain size parameters and the nomenclature of sediments can be developed to fill the gap in the field of classic sediment analysis techniques.
