Although considerable progress has recently been made in the evolution of marine traffic procedures in coastal and waterway areas, mariners are finding difficulty in coping with the diverse traffic schemes that have so far been devised. This paper is a plea for international and logical marine traffic management, so that ships can operate safely and efficiently within a framework of the proliferating offshore zonal legislation that we are now witnessing. 相似文献

中国风电事业经过近20年的发展取得了令人瞩目的成绩.到2000年底,国内已建立了24个风电场,总装机容量34.43万千瓦,但是未达到国家计委、国家经贸委和科技部三部委制定的"九五"计划期间装机40万千瓦的目标,与国家电力公司制定的装机100万千瓦的目标相差更远.风能利用发展速度不仅明显滞后于欧美等发达国家,而且已经落后于我们的邻国印度. 相似文献

Coastal zones are among the most productive areas in the world, offering a wide variety of valuable habitats and ecosystems services. Despite the low population density in the Brazilian coastal zone, their distribution is quite concentrated near some coastal cities and state capitals. This concentration places enormous pressure on coastal resources. Therefore, the main objective of this paper is to present an overview on the current status of SiMoCo (Sistema de Monitoramento Costeiro, or Coastal Monitoring System in English) project as a possible early warning system that can be integrated to the Brazilian Coastal Management Information System. This prototype platform provides a real-time access to the composition, organization and simulation of planktonic communities. First, our results demonstrate such a system detecting a target dinoflagellate; second, we apply structural and functional indexes to compare and characterize the ecological networks from two different coastal areas. Conclusions are made about SiMoCo’s feasibility and its possible contribution to the decision-making process within integrated coastal zone management (ICZM) strategies. 相似文献

“泰坦尼克”号沉没后,英国政府专门成立遇难情况调查委员会对事故进行细致的调查处理,调查报告认为海难的原因包括:号称“不沉之船”的“泰坦尼克”号自视结构设计绝对安全,绝不会沉没,从而没有准备充足的救生艇;“泰坦尼克”号的设计也存在一些漏洞;而海上无线电通讯不畅、缺乏应急预案等因素使海难升级。 相似文献

It is now some five years since the restructure of Australian ports and their transformation into corporatized entities. This strategy was adopted in an endeavour to improve efficiency by distancing government from day to day operations—the element that was perceived by many to be the cause of sub-optimal performance. While there is widespread agreement that port performance has improved significantly, dissatisfaction persists with the continued political intervention which is considered to be the reason for ongoing sub-optimal performance and ports' commercial potential from being realized. This paper investigates some of these issues but argues that political intervention per se should not be the focus of research and what is widely perceived to be the cause of the problem. Rather, that political intervention is an effect of something more endemic, of a legislative framework which may not be appropriate for the operations of a commercially focused port. It is argued that the focus should therefore be on the cause, a legislative framework, rather than the outworkings, or the effects of that framework. 相似文献
