Australian Wetland Water Environment Management and Technology Dynamic Integration     

An Zhengtao  Wei Yongping 《地球科学进展》2016,31(2):213-224

Australian government attaches great importance to the management of wetland water environment and the implementation of advanced technology, and has made large processes in the recent decades. Australia is one of the best country in global for wetland management and technology implementation. Based on the analysis of Australian government working method for wetland water environment management, two wetland water environment management and technology dynamic integration cases, and on the comparason ofthe differences of wetland water environment management between the two countries, including Murray-Darling Basin (MDB) and Lake Eyre Basin (LEB), it can be concluded that the success of Australian wetland water environment management is because of the following reasons: the dynamic integration between department establishment and technology, the dynamic integration between public participation and monitoring technology, as well as the dynamic integration between innovation policy and advanced technology. Furthermore, entity management method such as Murray-Darling Basin Authority (MDBA) is more adaptable and has longer lifespan. Such virtual management method as Lake Eyre Basin Intergovernmental Agreement is more flexible and has lower cost. The lessons learned from Australian government can help China manage wetland water environment.  相似文献   

Towards an EU Action Plan on Cetacean Bycatch     

《Marine Policy》2016

For decades, cetacean bycatch has been a major conservation and welfare concern in Europe, with high numbers of harbour porpoises, dolphins and whales continuing to die each year. Despite binding legal requirements to reduce bycatch, there has been limited effective monitoring or mitigation. Bycatch is also an important welfare issue. At this critical juncture, with discussion of incorporating monitoring and mitigation of bycatch of protected species in Europe into the Data Collection Framework and Technical Measures Framework taking place to help deliver the reformed Common Fisheries Policy (CFP), a clear, effective strategy could identify the steps that are required by all EU Member States to reduce bycatch towards zero. Here, implementation of current monitoring and mitigation obligations are reviewed. Recommendations are made for the provision of clear EU guidance in order to improve and unify population surveillance and bycatch monitoring, with enhanced implementation and enforcement from Member States. A more regionalised evidence-based approach to monitoring and mitigation is in line with the move to more regionalised management under the CFP, with Member States robustly showing that bycatch levels are decreasing over a set period of time (e.g. 5 years) by a specified amount. To this end, an EU Action Plan on Cetacean Bycatch, comparable to the existing 2012 Action Plan for reducing incidental catches of seabirds in fishing gear, might be beneficial and could ultimately form a model for an international Food and Agricultural Organisation (FAO) Cetacean Bycatch Reduction Action Plan.  相似文献

应用分布式存储技术优化省级CIMISS数据服务能力     

宋智  徐晓莉  张常亮  向筱铭  杨雪 《气象科技》2019,47(3):433-438

随着气象数据量的不断增长,进一步提升CIMISS数据管理和服务能力的需求变得日益迫切。为解决存储系统动态扩展能力不足、并行计算与吞吐效率低下等限制CIMISS继续发展的问题,采用分布式文件系统和NAS技术替代GPFS建设共享文件系统,实现非结构化气象数据的存储功能;采用分布式数据库替代Oracle RAC建设关系数据库管理系统,实现结构化气象数据的存储功能和非结构化气象数据的索引功能。实践证明,该方案能够有效地改善CIMISS的数据存储能力、并发响应能力,适应未来气象业务对数据存储和应用的需求。  相似文献   

Rational noncompliance and the liquidation of Northeast groundfish resources     

Dennis M. King  Jon G. Sutinen 《Marine Policy》2010

The results of a 2007 survey of fishers, managers, scientists, and enforcement officials indicate that noncompliance is a significant problem in the Northeast multispecies groundfish (NEGF) fishery, as it has been for at least 20 years. The percent of total harvest taken illegally is estimated to be 12–24%, which is significantly higher than estimates of 6–14% in the 1980s. Thirty-seven percent of fishers, 61% of fishery managers and 80% of fishery enforcement staff believe that “the combined adverse impact of all violations on the health and manageability of fish resources” is significant, highly significant, or extremely significant. Many fishers believe that illegal fishing will prevent them from ever benefiting from stock rebuilding programs.  相似文献

宣传贯彻《矿产资源法》促进依法治矿     

龚静夫 《湖南地质》1991,(1)

《矿产资源法》颁布实施五周年,通过宣传贯彻,增强了广大干部、群众依法办矿的法制观念,推动了各项矿管工作的开展,依法办矿的矿山取得了采矿权,非法采矿的小矿山被关闭,违法行为受到查处,矿管部门的声望越来越高,促讲了依法治矿。宣传贯彻《矿产资源法》要领导首先学法,提高认识,加强领导,建立一支专兼结合的宣传队伍,采取多种形式有重点地进行宣传教育。我国、我省面临矿产资源形势是严峻的,浪费矿产资源的现象仍存在,要继续深入宣传贯彻《矿产资源法》。  相似文献
