在国家自然科学基金面上项目和重大项目等资助下，中国科学院南京地理与湖泊研究所张运林研究组近日基于全国五大湖区1133对星地同步数据，构建和验证了全国湖泊透明度遥感估算模型（图1），并将模型应用于蒙新高原湖泊透明度反演及时空变化分析和驱动机制研究，相关成果发表在Water Research和Science of The Total Environment杂志上。
全球湖泊生态系统在气候变化和人类活动的双重胁迫下经历较大变化，特别是大型浅水湖泊，其退化和功能丧失的速率和幅度超越了地质历史时期，已制约到流域社会经济的发展和区域可持续性。蓝藻水华暴发态势对湖泊生态修复造成较大影响。
近日，云南大学张虎才研究团队在国际著名地学综合期刊Catena (2021年影响因子/JCR分区：5.198/Q1) 以“Potential catastrophic water outflow from Lake Dian, China: Possible hydrological and ecological risks”为题在线发表了关于滇池存在构造漏水隐患研究的阶段性成果。

The community composition and biomass of phytoplankton in shallow lakes are impacted by many environmental factors including water quality physicochemical parameters, land use in the watershed, and la...
以只经过大气瑞利校正的遥感反射率、气温和风速为输入，构建深度学习算法，可以绕过内陆水体精确大气校正难题，实现复杂富营养湖泊溶解有机碳浓度、储量和环湖河流碳通量的遥感估算。虽然，2008-2018年环太湖河流输运入湖的溶解有机碳净通量是太湖储量的约5.2倍，但太湖的溶解有机碳的时空变异主要受控于藻类生消过程。此外，强降雨是河流输运有机碳进入太湖的重要决定因素，苕溪河有近一半的入湖有机碳输运发生在强降...
Water quality degradation is one of the largest threats to freshwater ecosystems. Nutrient inputs, land use changes, and climate are expected to be the most important drivers of water quality degradat...
Semi-arid areas of northern China are under increasing pressures from anthropogenic activities and climate change. Although wetland areas in these drylands have experienced dramatic, unidirectional sh...
In temperate lakes, it is generally assumed that light rather than temperature constrains phytoplankton growth in winter. Rapid winter warming and increasing observations of winter blooms warrant more...

ater clarity (expressed as Secchi disk depth (SDD)) reflects light transmission capacity of a water body and influences growth of aquatic plants, aquatic organisms, and primary productivity.
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...
