A two step approach was developed to estimate POC concentrations in a shallow eutrophic lake, where dissolved carbon and inorganic particulate matter strongly influence optical properties. The approach was based on the identification of a co-variability of POC concentrations with one or more inherent optical properties (IOPs). In the present case, a relationship between POC and absorption at 62...

太湖是流域洪水集散地、水资源调配中心，也是长三角水生态环境的晴雨表，其水位高低影响防洪、供水、水生态、水环境等系统功能，使得太湖面临统筹调度问题日益凸显。本文以太湖为主要研究对象，基于多年实测数据，采用数理统计、河网水动力模型计算，分析流域降雨、进出湖水量和水生态环境演变规律及其与太湖水位的互馈关系，综合考虑不同调度期流域防洪、供水、水生态、水环境目标及其承受风险的时空差异性，优化太湖调度水位，并在此基础上提出太湖调度功能区划图。结果表明，在设计洪水和供水条件下，通过调度水位调整，统筹调控流域水工程，前期预降太湖水位，后期适抬太湖水位，实现太湖多目标调度，可有效保障流域防洪、供水和航运安全，改善河湖生态环境，共绘美丽太湖。;Lake Taihu is a center of flood distribution, water resources regulation, storage...

Harmful algal bloom (HAB) produced by several cyanobacterial species is a significant threat to many aquatic ecosystems around the world. Recently frequent occurrence of serious algal bloom in Lake Taihu, Lake Dianchi and Lake Chaohu has become a serious concern in China. Although various methods are currently being used to control toxic blue-green algal water blooms, many of their techniques a...

The most common natural disturbances in shallow lakes are wind-induced waves, which cause catastrophic changes in the aquatic fauna of lakes. Recovery from these changes is always prolonged. The objective of this study was to understand the resilience and recovery of the particle-attached bacterial community composition (PABCC) after frequent wind-wave disturbance in a large shallow eutrophic l...

The Ocean and Land Color Imager (OLCI) on the Sentinel-3A satellite, which was launched by the European Space Agency in 2016, is a new-generation water color sensor with a spatial resolution of 300 m and 21 bands in the range of 400–1020 nm. The OLCI is important to the expansion of remote sensing monitoring of inland waters using water color satellite data. In this study, we developed a dual b...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants in sediments and pose a serious risk for freshwater ecosystems. In this study, sediment samples from 24 sites were collected the cyanobacterial bloom-occurring, macrophyte-growing lake bay adjoining river of Taihu Lake. Here, concentration levels, sources, assessment 16 priority PAHs surface typical algae, macrophyt...
