Spatial–Temporal Wetland Landcover Changes of Poyang Lake Derived from Landsat and HJ-1A/B Data in the Dry Season from 1973–2019

Remote Sensing, 2020
As China’s largest freshwater lake and an important wintering ground for white cranes in Asia, the Poyang Lake wetland has unique ecological value. However, wetland cover types have changed dynamically and have attracted the attention of society and ...

The Seasonal and Spatial Patterns of Planktonic Bacterial and Fungal Community Structure and the Response to Environmental Factors in the Danjiangkou Reservoir, China

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
This study investigated the spatial and temporal distribution patterns of bacterial and fungal communities in the Danjiangkou Reservoir during dry season and wet season, revealing the mechanism by which seasonal variations drive changes in microbial community composition and function through their influence on the physicochemical properties of the ...

Spatial heterogeneity of vegetation extent and the response to water level fluctuations and micro-topography in Poyang Lake, China

Ecological Indicators, 2021
Wetland vegetation dynamics are vital but difficult to understand due to complex impact factors and their spatial heterogeneities. Poyang Lake, the largest freshwater lake in China, is well-known for its ecological importance as a floodplain wetland ...

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

Land Degradation &Development, Volume 37, Issue 9, Page 3715-3725, 30 May 2026.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

Advanced Science, Volume 13, Issue 26, 8 May 2026.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

A Numerical Study of the Effects of Density Contrast on Flow, Turbulence, and Mixing at the Negro/Solimoes Confluence, Brazil

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

Flood Forecasting Scheme for Poyang Lake

Journal of Water Resources Research, 2014
鄱阳湖为长江中下游洪涝灾害频繁的地区，鄱阳湖洪水预报方案研制对于科学调度鄱阳湖防洪减灾具有重要意义。本文分析了鄱阳湖洪水及其灾害特征，根据星子站实测水位与星子、湖口站前期水位、涨率、区间平均降雨量、五河七口入湖流量与湖口出流量之差进行相关分析，建立了湖泊水量平衡方案与多要素相关方程两种预报方案，用于鄱阳湖洪水作业预报。通过历史资料和应用检验，这些洪水预报方案可以取得较高的预报精度。Poyang Lake, located in the middle and lower reaches of Yangtze River, is the area that bears fre-quent flood disasters.

Observation‐Based Spatiotemporal Analysis of the Evolving Flood Regulation Capacity for the Yangtze River Basin

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The lack of direct observations for flood regulation capacity largely compromises our objective assessment of a basin's flood mitigation strategies in confronting global change. This study proposes a novel Precipitation‐Inundation Paired Events (PIPE) extraction frame‐work, which employs 3D clustering analyses of precipitation paired up with ...
