Lessons from a Multi-Scale Historical Reconstruction of Newfoundland and Labrador Fisheries

In this article we use a multi-scale, multi-method historical reconstruction of post– World War II social-ecological interactions within fisheries in Newfoundland and Labrador to explore the dynamics of intensification, expansion, and resource degradation in managed fisheries. Our case study draws on landings statistics, other archival information, and the Local Ecological Knowledge (LEK) of fish harvesters to explore these linked dynamics at the macro, meso, and micro levels. By some measures we found large scale trends toward intensification of effort leading to over-harvesting at macro (province wide) levels. At the same time, at the local level (micro-scale) and across sectors and regions (the meso-scale), we found highly fluid fishing practices and a complex suite of stated motivations for change. As a basis for effective governance, an understanding of the dynamics of interactive restructuring in social ecological systems will require multi-scale analyses that are sensitive to this complexity.     

鄱阳湖生态经济区文化软实力建设刍议

鄱阳湖生态经济区文化软实力建设是提升鄱阳湖生态经济区整体实力和竞争力的必然要求，是指基于已有文化资源，通过采取相应举措，增强其内在的凝聚力、生命力、创新力和外在的感召力、吸引力、影响力。丰富的文化资源是文化软实力建设的基础。鄱阳湖生态经济区文化资源转化为文化软实力还面临内在凝聚力不强、对外传播力不大等诸多困境，提炼核心价值观、加强传播力度、推进资源开发、吸纳优质人才、强化合作交流、构建长效机制是破解困境之策。     

Collaborative Integrated Management in Canada's North: The Role of Local and Traditional Knowledge and Community-Based Monitoring

The objective of this article is to take stock of integrated management in the Canadian North, assessing its contribution to the advancement of knowledge and practice regarding the role of indigenous knowledge and community-based monitoring. This is done in three steps. (1) The Beaufort Sea, designated a Large Ocean Management Area under Canada's Oceans Action Plan, is used as an example of a consultative planning process, with special attention to indigenous peoples. (2) How specifically can indigenous knowledge contribute to integrated management? The problem of Arctic marine food web contamination is used to illustrate the strengths and limitations of traditional ecological knowledge and its relationship to science. (3) The discussion of community-based monitoring relies on Voices From The Bay study involving the Inuit and Cree of Hudson and James Bay, and Inuit observations of climate change study in the Canadian western Arctic. The examples together address integrated coastal management and the health of ocean ecosystems, showing how stakeholder participation and knowledge helps widen the range of knowledge to understand and help monitor environmental change.     

长江中游戴家洲河段崩岸特性及护岸措施研究

在戴家洲右缘崩岸特点、崩岸机理分析的基础上,通过戴家洲右缘崩岸敏感性计算,分析了戴家洲右缘崩退与直港航道条件的关系。根据直港合理曲率半径以及崩岸敏感性计算结果分析了护岸时机,确定了对戴家洲右缘下段先进行守护,而戴家洲右缘上段待时机成熟后再行守护,并提出了先期护岸长度。对长江中下游已有护岸措施及其适应性进行了分析,在此基础上,提出了合理的护岸措施。

三峡库区下洛碛库段消落带生态护岸方案

三峡库区重庆渝北区下洛碛土质库段消落带因近岸采砂形成水下深槽,受江水冲刷库岸造成岸坡崩塌导致库岸线不断后移,区内生境已呈现不可逆转的破坏。为寻求一种兼顾环境、生态与经济的综合治理方案,通过现场勘察,在查明消落带地形地貌、岩土体特征、水文地质特征等的基础上,提出传统斜坡生态护岸和特拉锚垫生态护岸2种方案,并从施工工艺、护岸效果、生态恢复效果、施工周期、施工场地条件和后期养护成本共6个方面对比了2种方案的优缺点。结果表明,特拉锚垫生态河道系统护坡方案因其施工工艺简单、植物易活绿化覆盖率高、满足岸坡对江水侵蚀作用的防治需求等优势,更适合类似下洛碛库段消落带的江河湖泊和库区消落带土质和硬质岸坡的生态修复需求,可推广应用。
