Haiyang yu huzhao本文通过对比半月湾海滩历史岸线、剖面、水下地形、沿岸输沙等的变化，详细分析了海滩的侵蚀现状，探讨了渔港防波堤建设对半月湾海滩侵蚀的动力机制，并针对性地提出了海滩修复思路。研究结果表明，半月湾海滩自渔港防波堤建设以来产生了自西向东的沿岸净输沙，海滩西侧持续侵蚀，东侧持续淤积；2004~2014年西侧岸线蚀退速率最大约为-8.10 m/a，东侧淤进速率最大约为10.10 m/a；2015~2017年年单宽净侵蚀量最大约为10.99 m3/m，2017~2021年单宽净淤积量最大约为26.05 m3/m；岸线、

International Journal of Urban and Regional Research, EarlyView.Abstract From desert ski resorts to subtropical Winter Games, there is a global proliferation of ‘mission‐impossible’ mega‐projects. The prevailing frameworks of city branding and urban entrepreneurism fail to explain the political logics behind these seemingly irrational projects.

Journal of Analytical Psychology, EarlyView.Abstract This paper explores what is happening, for a trainee, when an ethical boundary violation occurs by the analyst with a fellow peer in training. I am approaching this through the Jungian concept of the alchemical vas as I attempt to make meaning of a catastrophic collapse of the analytic work.

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

, 2006 生态资产是指生态系统的间接生态服务价值。本研究综合运用生态学和经济学方法，基于现有的科学技术水平和统计资料、环境监测数据，按照城市湿地、城市森林、城市草地、城市郊区农作物和城市游憩类生态资产五项构建了城市生态资产评估体系。由于城市游憩类生态资产，是由城市湿地、森林、草地、郊区农作物相互作用带来的，而且它们所产生的游憩类资产没有明确的界线，所以，把城市湿地、森林、草地、郊区农作物所产生的游憩类生态资产合并为城市游憩类生态资产单独计算。 草地、农作物与森林所具有的生态资产价值类型相同，只不过数量上有差异 ...
