Systematic Evaluation and Influencing Factors Analysis of Water Environmental Carrying Capacity in Taihu Basin, China

Zhibing Hu et al.

Summary: The evaluation of water environment carrying capacity is a prerequisite for achieving sustainable development and reflects the comprehensive condition of the water environment in a lake basin under current economic development. A comprehensive evaluation index system of water environment carrying capacity was established based on the case study of Taihu Basin, including water resources, pollution emissions, water quality, water ecology, and land use subsystems. According to the evaluation results, the water environment carrying capacity index of Taihu Basin increased by 51.4% from 2007 to 2019, but still slightly exceeded the carrying capacity of the water environment.

Bloom-induced internal release controlling phosphorus dynamics in large shallow eutrophic Lake Taihu, China

Lijuan Kang et al.

Summary: This study found that high phosphorus concentrations are common in eutrophic lakes during algal blooms, despite previous efforts to reduce external nutrient inputs. Through extensive nutrient monitoring in Lake Taihu and its tributaries over a five-year period, it was determined that internal phosphorus loading has a significant impact on phosphorus dynamics. The study showed that the in-lake total phosphorus stores ranged from 398.5 to 1530.2 tons, and the annual internal phosphorus loading accounted for approximately 115.6% of the external inputs on average. The findings highlight the importance of considering internal phosphorus loading and ecosystem restoration in eutrophic lakes, particularly in regions dominated by algal blooms.

Characterization of internal phosphorus loading in the sediment of a large eutrophic lake (Lake Taihu, China)

Hongbin Yin et al.

Summary: This paper provides a detailed investigation of sediment internal P loading in Lake Taihu and its role in algal dominated zones (ADZs) and grass dominated zones (GDZs). The results show that ADZ sediments have higher levels of total P and mobile P fraction compared to GDZ sediments. The study also identifies ADZ as a hotspot for P, with high concentrations of DGT-measured P. Sediment microbial composition is found to be closely related to different P fractions in the sediment. The findings highlight the importance of considering the sediment composition and different management strategies for combating internal P loading in ADZ and GDZ.

An ecologically dispatch strategy using environmental flows for a cascade multi-sluice system: A case study of the Yongjiang River Basin, China

Xi Weng et al.

Summary: The construction of estuary sluice has significant negative impacts on the ecological environment, which can be mitigated by an ecologically oriented multi-sluice system operation strategy to meet the diverse environmental flow requirements of different fish species. By predicting effective habitat through modeling and adjusting river discharges, the study aims to maintain the needs of fish for spawning and migration.

Environmental controls of harmful cyanobacterial blooms in Chinese inland waters

Hai Xu et al.

Summary: Harmful cyanobacterial blooms are expanding in China's inland waters, with varying environmental factors controlling their dynamics. Shallow water bodies in China are highly susceptible to human activity and changing climatic conditions compared to deeper lakes. Rapid urbanization and industrialization, combined with climate change, have accelerated the onset and proliferation of cyanobacterial blooms in these regions.

Contributions of external nutrient loading and internal cycling to cyanobacterial bloom dynamics in Lake Taihu, China: Implications for nutrient management

Hai Xu et al.

Summary: Despite extensive abatement efforts focused on external phosphorus loading, harmful cyanobacterial blooms persist in Lake Taihu. Internal nutrient cycling plays a key role in sustaining these blooms, with nitrogen leaving the lake faster than phosphorus, creating persistent nitrogen limitation.

Identifying major contributors to algal blooms in Lake Dianchi by analyzing river-lake water quality correlations in the watershed

Jing-Han Wang et al.

Summary: Globally intensified hazardous algal blooms pose threats to public health and ecosystems. River-lake water quality differences were studied from 2010 to 2015, showing that riverine pollutants, especially CODCr and nutrients, had significant impacts on lacustrine HABs. Water temperature and suspended solids were identified as positive correlation factors with HABs, while dissolved oxygen was a negative factor. Recommendations for lower nutrient limits in inflow rivers and Lake Dianchi were proposed to mitigate HABs in the lake.

Extreme Climate Anomalies Enhancing Cyanobacterial Blooms in Eutrophic Lake Taihu, China

Boqiang Qin et al.

Summary: The study finds that regional climate anomalies exacerbate eutrophication in Lake Taihu by intensifying internal nutrient cycling and aggravating cyanobacterial blooms, resulting in a positive feedback mechanism. These regional effects of climate anomalies are nested within larger-scale global warming predicted to continue in the foreseeable future, contributing to the global expansion of eutrophication and blooms, especially in large, shallow, and eutrophic lakes.

Water quality assessment of Loktak Lake, Northeast India using 2-D hydrodynamic modelling

Eliza Khwairakpam et al.

Summary: This paper applies a physically based 2D hydrodynamic model to simulate the transport phenomena and water quality of Loktak Lake, revealing deterioration primarily caused by pollutants from sub-catchments. The study successfully simulated dissolved oxygen and biochemical oxygen demand in the lake using MIKE 21 ECO Lab.
