Abstract:
Sediment granularity, if well studied, can reflect regional natural environment and its change. This paper, based on a surface sampling 0~20 cm in a typical micro-physiography in northwest Shandong province, applies laser granularity analyzer to study the granularity with the results indicating that the regional surface sediment grains are similar with regional stream grains, which are chiefly siltstone. The spatial differentiation of sediment granularity is controlled by micro-physiography formed by alluvion and deposit swing and by paleoclimate, and by, as well, human’s irrigation from Yellow River.
Key words: micro-physiography; sediments; northwest Shandong province

摘要:
沉积物粒度研究对研究沉积区域自然环境特征及变化有重要意义。对鲁西北地区典型微地貌表层0~20 cm沉积物进行采样,利用激光粒度分析仪进行粒度分析。分析结果说明区域表层沉积物颗粒与区域河流泥沙颗粒组成相似,以粉砂为主;沉积物粒度表层空间分异与古河流冲积、河床摆动形成的微地貌控制及气候等自然要素有关,也受人类引黄灌溉、抽水灌溉等社会因素影响。
