正随着世界经济一体化发展,港口物流业日益兴盛,集装箱码头规模快速扩张。例如,长三角经济带的主要国际港口上海港洋山深水港区建成四期自动化集装箱码头,宁波舟山港先后建设穿山港区和梅山港区,泊位数量均在10个以上。在此形势下,港口集装箱码头安全管理工作面临着更加艰巨的挑战。随着集装箱码头规模不断扩大,传统的制度化安全管理模式需要优化升级,以确保生产安全。 相似文献

目前国外已建成的全自动化集装箱码头大部分采用自动引导车(AGV)作为水平运输设备。AGV在实现集装箱码头水平运输机械全自动化的同时,改变了传统码头设备维修模式,对码头总平面布局中机械维修功能区布局产生较大的影响。如何科学合理布置自动化集装箱码头的AGV维修区,成为提高码头运行效率和充分利用土地资源的关键问题。在总结分析国外典型自动化集装箱码头AGV维修功能区实际案例布置基础上,结合目前技术发展及港口整体发展要求,提出了几种新的布置方案,并在我国大型全自动化集装箱码头——洋山四期工程得到实际应用。 相似文献

目前,煤炭销售形式非常好,但有的煤矿经济效益并不如人们所期望的那样高,究其原因主要在于煤炭的生产成本比较高。而节能降耗是煤矿降低煤矿生产成本提高经济效益的主要途径,尤其是针对煤矿中大型机电设备的节能改造是煤矿降低生产成本的主要方式。因此,煤矿需要比较设备不同的运行方式,分析不同情况下的效率,制订节能的运行方案。 相似文献

许多中小城市特别是北方地区房屋建筑至今尚未大面积实施墙体节能设计及管理,以致造成了不必要的采暖能源损失,建筑物外墙出现“热桥”、室内墙面大面积起毛发霉等质量问题时有发生。其主要原因是采暖居住建筑地区外墙保温水平低、热环境质量差、采暖能耗大,不符合节能标准,甚至在某种程度上影响居民的身心健康,给社会带社会来不安定因紊。 相似文献

This article uses the Central Coast region of California as a case study to examine the challenges of protecting coastal ecosystems near areas of intensive agricultural production. Coastal water quality and biodiversity are greatly impacted by regional land use. Agricultural land use can have significant impacts on water quality through erosion and the runoff of agricultural chemicals. While the Central Coast region of California is a center for intensive agricultural production, it is also home to the largest marine sanctuary in the United States. This combination has resulted in intensive efforts from government agencies and conservation organizations to reduce pollution associated with agriculture. Efforts have focused on education and incentives, but are recently facing increasing challenges stemming from new standards created by the produce industry in response to food safety concerns. Personal interviews with crop growers were used to explore these challenges and to better understand the range of possible environmental impacts resulting from new food safety standards. Results indicate that substantial management changes are taking place that are likely to impact regional water quality and wildlife. This case study also explores the role of policy networks in shaping management decisions and illustrates how certain approaches to addressing agricultural pollution may be vulnerable to external policy changes. 相似文献

This special issue provides insight into global conservation science by analyzing a 5-year, $12.5 million global marine conservation science and policy program that included over 50 studies in four priority regions involving over 100 scientists and numerous partners. In doing so, it provides reflections on critical challenges for any conservation science program that is intended to inform policymaking, including how to (1) ensure that science process and products influence conservation actions, (2) build global learning from a network of site-based projects, (3) strengthen in-region capacity, and (4) manage relationships across scales among scientists, conservationists, headquarters, and field-based staff. Information is presented on the development and progress of the program as a whole in addition to specific articles covering each of four focal geographic areas: Belize, Brazil, the Eastern Tropical Pacific Seascape, and Fiji. 相似文献

Drawing on experiences from the four regions and the overall conduct of the Marine Management Area Science (MMAS) program, this concluding article highlights emergent cross-cutting themes that affected MMAS programs across the regions, summarizes the important conservation outcomes of the MMAS program, and then discusses lessons gained from the actual process of conducting the MMAS program. Based on these insights, particularly the last section, this article concludes with recommendations for other conservation programs, specifically those that are global in scope and are science-based with a specific intent to apply that science to conservation action. 相似文献
