Photodegradation of humic acid from the surrounding soils of a sub-alpine Lake Tiancai Open
溶解性有机质(DOM)是湖泊生态系统的物质循环和能量流动的基础.典型亚高山湖泊DOM的主要来源为流域土壤腐殖酸(外源DOM),其具有较强的光吸收特性,光降解是其重要的转化过程,从而改变碳、氮、磷等物质的存在形式.在气候变暖的背景下,亚高山湖泊中DOM的浓度、pH、溶解氧及太阳辐射都可能发生变化;但这些环境变化对亚高山湖泊DOM光降解过程的影响尚不够清楚.由此本文研究了亚高山湖泊——天才湖(树线下200 m)周边土壤提取的腐殖酸(THA)的光降解过程:首先考察在光源为500 …

The responses of the benthic-pelagic coupling to eutrophication and regime shifts in shallow lakes: Implication for lake restoration Open
浅水湖泊中的初级生产者主要由分布在底栖生境中的底栖植物和生活在敞水生境中的浮游植物组成.底栖植物主要包括维管束沉水植物和底栖藻类等,浮游植物则主要为浮游藻类.贫营养浅水湖泊湖水营养盐浓度低,透明度高,底栖植物因能直接从沉积物中获取营养盐,往往是浅水湖泊的优势初级生产者.随着外源营养盐负荷的增加,湖水中的营养盐浓度不断升高,浮游植物受到的营养盐限制作用减小,加上其在光照方面的竞争优势,逐步发展成为湖泊的优势初级生产者,湖泊逐步从底栖植物为优势的清水态转变为浮游植物为主的浑水态…
