Eutrophication and algal blooms have frequently occurred in Chaohu Lake. Water parameters interact with eutrophication blooms. However, there are few studies on the spatial–temporal characteristics of water Lake Basin. To assess quality its seven surrounding rivers, 132 samples from 33 sites were collected seasonally September 2019 to July 2020, 14 physicochemical detected. Our results showed that urban rivers had highest nutrients, chemical oxygen demand (CODMn, 6.30 ± 0.80 mg/L), five-day biological (BOD5, 4.51 0.42 chlorophyll a concentration (Chl a, 54.88 39.81 μg/L); forested higher transparency (137.83 18.52 cm), lowest CODMn (4.02 0.20 BOD5 (1.42 0.14 Chl (7.18 1.41 agricultural mixed intermediate.

Prediction of Future Chlorophyll‐a Concentrations in Large Eutrophic Shallow Lakes Under Multiple Stressors

Earth s Future, Год журнала: 2025, Номер 13(5)

Опубликована: Май 1, 2025

Abstract Assessing future chlorophyll‐a (Chl‐a) changes is crucial for developing effective lake management programs. Future assessments should integrate socio‐economic and climatic factors, including extreme climate impacts. However, such are lacking. This study developed a novel framework integrated model to analyze Chl‐a response in Chaohu Lake (e.g., precipitation, temperature, wind) population, fertilizer application, livestock farming). The results indicated that by around 2050, the concentration would change −6.5% −0.1% compared 2020. While factors significantly altered nitrogen phosphorus loading, exogenous loading had minimal effect on due high endogenous releases. decrease mainly increase precipitation. reduction was primarily driven increased precipitation (0.6%–12.9%), leading −9.4% −4.4% changes. runoff also provided an opportunity treat heavily polluted area. Air temperature increases of 5.1%–9.2% resulted 0.9%–3.1%. On annual scales effects were mean values. variability significant at seasonal scales, example, lower spring temperatures favored summer Chl‐a. There uncertainty about impact wind speeds. emphasized importance comprehensively quantifying impacts external pressures water quality assessment reference pathway support large, shallow lakes.

A Review on the Driving Mechanism of the Spring Algal Bloom in Lakes Using Freezing and Thawing Processes

Water, Год журнала: 2024, Номер 16(2), С. 257 - 257

Опубликована: Янв. 11, 2024

Spring algal blooms in mid–high-latitude lakes are facing serious challenges such as earlier outbreaks, longer duration, and increasing frequency under the dual pressure of climate warming human activities, which threaten health freshwater ecosystems water security. At present, freeze-thaw processes is key to distinguishing spring mid- high-latitude from low-latitude lakes. Based on visualization an analysis literature WOS database during 2007–2023, we clarified driving mechanism process (freeze-thaw, freeze-up, thawing) bloom by describing evolution nutrient migration transformation, temperature, lake transparency dissolved oxygen, physiological characteristics algae between shallow deep We found that complex phosphorus transformation frozen period can better explain spring-algal-bloom phenomenon compared nitrogen. The dominant species also undergo process. On this basis, response future change has been sorted out. general framework “principles analysis, model construction, simulation prediction, assessment management” prevention strategy for dealing with have proposed, would like provide scientific support reference comprehensive control freezing thawing processes.
