| 摘 要： | 河流是陆地与海洋相互作用的重要纽带,查明陆地河流活性物质入海通量是当前生态地球化学评价的一项重要任务。文中选择了中国东部入海河流中主要的35条河流,分丰、枯水期系统采集了悬浮物、过滤水、底泥等样品,利用河流径流量参数,计算得到了各河流主要重金属及营养元素的年入海通量及陆地河流年入海总通量,确定了各元素水溶态及悬浮物态迁移入海量的比例,为陆海相互作用研究、浅海生态地球化学评价提供了重要依据。

| Abstract: | River is a bridge between terrene and ocean. It is very important to study the flux of river active material flowing into the sea for current ecological geochemical evaluation. We have chosen 35 major rivers flowing into the sea in Eastern China and collected the samples of suspended particulate matter (SPM),filtered water and bed mud both in dry seasons and wet periods. By analysing these samples and using the runoff data of these rivers,we calculated the annual flux of major heavy metals and nutritive ele... |
