Research Trends and Ecological Water Levels in Poyang Lake

A 2026 bibliometric review and quantitative synthesis of research on ecological water levels in China's Poyang Lake. The study, authored by Yanhui Zhang and shared on figshare, analyzes publications from CNKI and Web of Science databases. It identifies key research clusters and quantifies annual and monthly ecological water level thresholds.

Use Cases

• Bibliometric analysis of research trends in ecological water level studies based on the identified clusters from CNKI and Web of Science.
• Quantifying hydrological thresholds for ecosystem management based on the reported minimum and optimal ecological water level values.
• Assessing the impact of dam operations and climate change on wetland hydrology based on the described research focus areas.
• Designing monitoring strategies for critical wetland habitats based on the identified data gaps regarding spatial resolution and species-specific requirements.

Strengths

• Provides specific quantitative thresholds, including an annual minimum ecological water level of 9.71 ± 1.94 m and an optimal level of 12.53 ± 2.01 m.
• Identifies clear monthly patterns, with ecological water level requirements peaking from July to August and reaching their lowest in January.
• Uses a structured methodological approach combining bibliometric analysis with quantitative synthesis of existing research.

Limitations

• The primary data file is a 48.2 KB PDF, suggesting the dataset is a document summary rather than a raw data repository.
• Row count and column-level documentation are absent, limiting assessment of underlying data structure and granularity.
• The description notes inherent data limitations, such as insufficient spatial resolution of hydrological station data and weak links between water levels and specific biotic requirements.
