| 1 | ^(210)Pb沉积速率测定法在浅水动力环境中的应用显示文摘本文根据瓦登海(Waddensea)潮滩沉积物。^(210)Pb强度的测定和有关实验,讨论了^(210)Pb沉积速率测定法在浅水动力环境中应用所存在的一些问题和原因;提出了^(210)Pb“转换时间”和“沉降时间”概念;分析了泥沙运动与沉积物^(210)Pb强度的关系并依据粒度指标对某些不规则^(210)Pb剖面进行修正;发现Jade湾潮滩现代沉积速度为0.16—0.29cm/a,Greetsiel为0.16cm/a,Afsluitdfijk大坝附近达6.0cm/a,反映了大坝工程改变动力环境后出现的聚淤现象。 | 陈卫跃 沈健 D.

| 2 | SIZE DISTRIBUTION OF SUSPENDED SEDIMENT IN MAXIMUM TURBIDITY ZONE AND ITS RESPONSE TO TIDAL DYNAMICS IN THE JIAOJIANG RIVER ESTUARY显示文摘This paper discusses the change of the size distribution of suspended sediment, both in the region and over the tidal cycle, by means of statistics and calculations of different size fractions and median diameters. It also indicates that the size distribution is mainly influenced by three factors, i.e. sediment sources, re-suspensions of the bottom sediment and flocculated settlings. Of which, the action of the resuspension is more remarkable during the spring tide than during the neap tide, while the action of the flocculation is more pronounced during the neap tide than during the spring tide. | LI Bogen, XIE Qinchun, D.

| 3 | DEPOSITIONAL CHARACTER AND SHORELINE CHANGES OF THE NANDUJIANG DELTA,HAINAN ISLAND,CHINA显示文摘The Nandujiang delta dates from at least 3000 yr ago and probably was fomred earlier during the Holocene. The present delta is built up of plain, channels, lagoos, spits, coastal barriers and beaches.Tidal currents are directed approximately east-west. The dominant waves come from NNE and are locally generated. Erosion occurs mainly on the east side of the delta. As the delta was growing outward into deeper water, the influence of marine processes increased and the delta changed from a river-dominated delta. Former branches were closed by littoral drift. The recent reduction in sediment suppy from the river, caused by the construction of a reservoir, has led to erosion of the coast. Three coastal sections of the delta are discussed in detail. Erosion mainly taks place on the foreshore and spits and barriers migrae inland covering former lagoon deposits. Measures to reduce further erosion and landward migration of the coastline are needed. | Wang Baocan Zhang Keqi(East China Normal University, Shanghai 200062 China People’s Republic of China)D.
