China's instrumentalist greenisation of the new‐generation IIAs
Review of European, Comparative &International Environmental Law, EarlyView.Abstract In the context of the global trend of greening international investment agreements (IIAs) after Rio+20, China is taking a more active role in greening its IIAs than before, albeit with inconsistent patterns. This article analyses the driving factors for its change after Rio+20 and argues that China's IIA greenisation is instrumentalist at ...

The foraminiferal taxa in surface sediment and its environmental implication in Sansha Bay [PDF]
, 2016 有孔虫对所生存的环境变化较敏感。对于不同的水深、温度、盐度、pH、沉积速率等环境因子的变化，有孔虫群落特征会发生相应变化。故有孔虫群落特征能较好地反映海洋环境变化。由于季节的变化，夏季和冬季所对应的环境因子条件不同，其有孔虫群落特征也会发生相应变化。本论文根据福建三沙湾的夏冬季24个站位表层沉积物样品，进行有孔虫鉴定和沉积物粒度分析。在广泛收集前人资料及室内分析的基础上，结合表层沉积物中七种重金属含量平面分布特征，通过研究分析有孔虫种群的空间分布及其与环境因子间相互关系 ...

At the controls: Politics and policy entrepreneurs in EU policy to decarbonize maritime transport
Review of Policy Research, EarlyView.Abstract The recent adoption of the FuelEU Maritime regulation, aiming to decarbonize maritime shipping, is part of the EU clean energy transition to reach carbon neutrality by 2050. Based on autoethnographic method and qualitative text analysis, applying the multiple streams framework as a theoretical lens, this article explores and explains the ...

Secondary productivity of macrobenthos in mangrove and salt marsh in Gaoqiao of Zhanjiang,Guangdong Province of South China [PDF]
, 2012 为了比较湛江高桥潮间带不同植物生境的大型底栖动物次级生产力,根据2010年4个季度湛江高桥潮间带生境的大型底栖动物数据,运用brEy经验公式计算不同植物生境的大型底栖动物次级生产力.结果表明:湛江高桥红树林和盐沼湿地不同生境大型底栖动物平均次级生产力为11.77gAfdM·M-2·A-1.其中,无瓣海桑生境次级生产力最高,为18.16gAfdM·M-2·A-1,其次是桐花树、盐地鼠尾粟和木榄生境,分别为17.67、8.34和2.92gAfdM·M-2·A-1.在4种生境中,木榄生境的年生产力/年均生物量(
