南北极是研究全球变化的关键区域。＂十一五＂期间我国在南极地区系统开展了东南极冰盖/冰架变化监测与预测技术研究,对认识全球气候变化具有重要作用。通过项目实施,建立和发展了一批现场观测体系,发展了冰盖观测新技术并集成应用于东南极冰盖的综合观测,拓展了对冰穹A地区的新认识和新发现;在冰穹A边缘地区钻取的一支浅冰芯恢复了过去约780年的气候记录,记录了东南极地区存在小冰期的明显证据;发展了东南极冰盖积累和等时年层流动模型,研究在冰盖浅层、中层和深部的变化特征,反演了冰穹A地区的古积累率分布。本文概要介绍该项目基本情况。  相似文献   

Engaging stakeholders in fisheries and marine research     

S. Mackinson  D.C. Wilson  P. Galiay  B. Deas 《Marine Policy》2011

Despite knowledge-brokering being of high interest to public policy, there is a lack of research integrating the knowledge of stakeholders and scientists, principally because public policies remain viewed as top-down controlled. To help European research policies make a positive difference to society, there is a need to better engage stakeholders with the delivery of research and to demonstrate an impact and value that it brings. The pertinent question addressed by this communication is: how can a deeper and more systematic engagement of stakeholders be enabled through European research activities? Enabling stakeholder participation in European research activities requires there to be an incentive for researchers and stakeholders to engage, and the capacity of stakeholders to operate effectively in the research framework. Unsurprisingly, the establishment of communications and cultures conducive to shared problem solving is high priority, as is the need to work towards a governance structure that helps link research with policy outcomes, while at the same time resonating directly with stakeholders. The Regional Advisory Councils could be a strong force in bringing stakeholders knowledge to bear on the scientific issues relevant to management, but their strategy and capacity to mobilise the skills to do so are not yet ready.  相似文献

Conventional sectoral management and piecemeal governance are considered less and less appropriate in pursuit of sustainable development. Ecosystem based marine spatial management (EB-MSM) is an approach that recognizes the full array of interactions within an ecosystem, including human uses, rather than considering single issues, species, or ecosystem services in isolation. Marine spatial planning and ocean zoning are emerging concepts that can support EB-MSM. EB-MSM is driven by high-level goals that managers aim to achieve through the implementation of measures. High-level goals and objectives need to be translated into more operational objectives before specific targets, limits and measures can be elaborated.Monitoring, evaluation and adaptation are necessary to ensure that marine management measures are both effective and efficient. Solid monitoring frameworks are the foundation of adaptive management, as they provide the necessary information to evaluate performance and the effectiveness of management actions. Marine protected areas (MPAs) - possibly set up in networks - constitute a key component in EB-MSM policies and practises and have been applied as a cornerstone in conservation of marine biodiversity, management of fish populations, development of coastal tourism, etc. Moreover, MPA experiences have provided methods and concepts (such as zoning) to a wider EB-MSM context. The assignment of values to biophysical features of the marine environment allows the direct assessment of related management choices and may assist EB-MSM.A range of monetary valuation techniques have been proposed to reduce attributes of goods and services to a single metric. However, in the marine environment such an approach is often over simplistic, and thus less reductive techniques may be necessary. Rather than producing a single metric, the results of non-monetary assessments guide policy allowing weight to be given as necessary to potential areas of conflict and consensus.Strategies to take into account climate change effects and geohazard risks in EB-MSM have been applied or proposed worldwide. EB-MSM regimes must be alert to such risks and flexible to account for changes.  相似文献   

西藏高原强对流天气及短临预报研究进展

Research progress on evaluation frameworks of regional ecological sustainability   总被引：1，自引：0，他引：1

As natural ecosystems provide the material basis and fundamental support for regional sustainable devel-opment,the sustainability of natural ecosystems is an important prerequisite and a viable approach for the achievement of regional sustainable development.It is also the final criteria to assess whether sustainable development paradigm is successful.Along with the increasing impacts of human activities on natural ecosystems,the evaluation of regional ecological sustainability has become one of the key issues for research on macro ecology and sustainable development.Based on different unit of indicators,this study firstly groups the evaluation frameworks of regional ecological sus-tainability into three major types:comprehensive index evaluation with dimensionless unit,monetary valuation,and biophysical quantity measurement.We then discuss and compare these types in terms of basic principles,scope of ap-plications,advantages and shortcomings.Finally,drawn on the discussion about characteristics of ecological sustain-ability,we outline the current trend and future directions of regional ecological sustainability evaluation,for instance,transition from sustainable development evaluation to sustainability science,integration of goal-oriented and problem-solving approaches,combination of spatial pattern analysis and ecological sustainability evaluation,and en-hancement of ecological sustainability evaluation at landscape scale.  相似文献
