摘    要:以鸭绿江口西汊道连续性较好的柱状沉积物为样本,对其210Pb年代、粒度特征和粒度参数进行了测定和分析,发现人类活动在沉积记录中有良好的粒度响应。其中,粒度对围海造地、航道治理等人类活动带来的河床演变最为敏感,水库拦截作用的粒度响应也比较清楚,对流域内的其它人类活动的粒度响应相对较弱。

关 键 词:鸭绿江口  人类活动  粒度响应

Abstract:The 210Pb dating,grain size characteristics and grain size parameters of core sediments with by better continuity collected in West-branch-way of Yalu River estuary were analyzed.It was found that human activities had good response to grain size.Among them,land reclamation and waterway regulation were the most sensitive factors to riverbed evolution.The interception effect of reservoir was also clear.The response of grain size to the other factors in human activities was relatively weak.
Keywords:Yalu river  human activity  grain size response
