Lakes are important sources of greenhouse gases (GHGs) to the atmosphere. Factors controlling CO2, CH4 and N2O fluxes include eutrophication and warming, but the integrated influence of climate-warmin...
Lake warming induced by climate change has constituted a particular challenge for the restoration of eutrophic lakes. However, a quantitative analysis about impacts of lake warming on the internal nut...

富营养化 湖泊底泥 内磷负荷 吸附剂

Dredging and in situ adsorbent inactivation are two methods which are frequently used in eutrophic water bodies such as ponds, lakes and estuaries to control internal phosphorus (P) loading from sedim...
厌氧硫酸盐还原作用在水体有机物代谢、沉积物内源磷释放、和致黑物质产生等方面都有重要影响。以往研究表明水柱中厌氧硫酸盐还原主要发生在海洋缺氧区和自然分层的深水湖泊中。而对于浅水湖泊而言，通常认为难以发生持续的厌氧硫酸盐还原作用。
湖泊溶氧反映的是大气富氧与植物光合作用放氧过程和生物呼吸作用耗氧过程间动态平衡，较低的溶氧水平不仅影响湖泊氧化还原电位进而增加氮磷营养盐释放和有毒重金属的毒性，还会影响鱼类和无脊椎动物的分布与生长。因此，较高的溶氧水平条件是维系一个良性湖泊生态系统的关键要素。Hutchinson早在1957年就提出：“比起其他任何化学参数，对溶氧的分析更能让湖泊学家了解湖泊的特性，再结合透明度、水色及其他水体形态...
