滨州港海域沉积物特性分析 总被引:2,自引:1,他引:1
依据2008年1月、2006年3月和7月的黄骅港、滨州港海区沉积物取样资料,对海床泥沙中值粒径、细颗粒泥沙含量、分选程度等平面分布特征进行了分析,并与黄骅港海域的泥沙底质进行了比较,结果表明滨州港的兴建阻挡了港岛以南床面泥沙的北移,部分遏制了泥沙来源,同时滨州港外航道成为从南到北泥沙输移的沉沙池,对减少黄骅港外航道泥沙淤积有利。 相似文献

描述了《水道港口》期刊近年影响因子变化及期刊传播趋势,同时选择影响因子和即年指标与同类期刊进行了对比分析。分析显示,自2001年以来,《水道港口》的影响因子经过5 a的波动后,自2006年起呈总体上升趋势,表明了《水道港口》现已进入了可持续发展的轨道。该期间的即年指标变化趋势亦佐证了这一点。 相似文献

随着舟山港油轮运输的不断增加,溢油风险事故的发生越来越大。为了避免污染带来的损失,溢油轨迹预报显得非常重要。本文利用舟山海域环境动力场的预报方法获取比较准确的环境条件,应用溢油模型,结合海区的环境场模拟溢油的运动轨迹,并在电子海图上实现了溢油信息的可视化。 相似文献

Ports are marine gateways to economic activities. Ports’ ability to perform services depends on their facilities, harbor conditions, and other factors. Generally, ports have control over their facilities but must compete for funding to improve them. As for waterways, in the U.S., a Harbor Maintenance Trust Fund was established to fund dredging, which levies a 0.125% cargo value tax on most shippers using U.S. coastal and Great Lakes harbors. Yet, commonly, a gross tonnage metric is used to allocate the fund’s resources, resulting in under-maintenance of some harbors. This, reportedly, deters additional port funding and hinders valuable commerce. Supplemental economic metrics, such as value of commerce or cargo, can improve port financing decisions, but such data is not readily available. Container ports collect cargo value data in nominal terms, but bulk ports do not. When making economic decisions, however, real values must be used. Further, when allocating resources, decision-makers must be able to assess ports over time and relative to each other. Conforming to these criteria, this paper develops three port financing indicators based on a real value of cargo and illustrates their calculations using the U.S. Port of Duluth-Superior as a case study. 相似文献
