黄河源区弯曲河流演变过程与机理=Morphodynamic Processes andMechanism of Meandering Rivers in the Source Region of Yellow River 李志威,王兆印 著.pdf

本书以黄河源区弯曲河流为研究对象,采用长期野外考察、原型观测与实验、遥感解译、力学理论分析与概化模型实验相结合的综合方法,对黄河源区草甸型与泥炭型弯曲河流演变过程和机理进行系统研究。全书主要内容包括研究背景与意义,黄河源区弯曲河群空间分布、形态特征与边界条件,草甸型与泥炭型弯曲河

渤海、黄海和东海沉积物类型图=Sediment Type Map of the Bohai Sea,Yellow Sea and East China Sea:汉英对照.pdf

《渤海、黄海和东海沉积物类型图》(1:100万)共分6幅,是根据我国几十年来实施的多个海洋调查专项及其他调查研究项目获取的17145站沉积物实测数据,并结合收集的数据资料编制而成的,反映了中国东部海域沉积物类型的分布格局和变化规律。本图说明书在详细阐述沉积物类型、粒度参数和沉积速率分布特征的基础上,揭示了渤海、黄海和东海现代沉积物物源及输运过程,并讨论了该区若干沉积学热点和前沿问题。
