Nutrients transport behavior in inlet river in the Yellow River Delta in winter

Marine Pollution Bulletin, 2023
The nutrients such as dissolved inorganic nitrogen (DIN, NH4+-N, NO2--N, and NO3--N), dissolved inorganic phosphorus (DIP, PO43-) and dissolved SiO2 (DSi) funneled by the inlet river are the dominant factors to coastal eutrophication. This study investigated nutrient transport process in typical inlet rivers in the Yellow River Delta.

Salinity Effects on Microbial Derived-C of Coastal Wetland Soils in the Yellow River Delta

Frontiers in Ecology and Evolution, 2022
Microorganisms play a crucial role in regulating the turnover and transformation of soil organic carbon (SOC), whereas microbial contribution to SOC formation and storage is still unclear in coastal wetlands. In this study, we collected topsoil (0–20 cm)

An overview of ecohydrology of the Yellow River delta wetland [PDF]

Ecohydrology & Hydrobiology, 2016
The combined effects of geophysical and ecological processes, such as water and sediment load, land use change, eustatic sea level rise, land subsidence, and wetland loss, have produced a dynamic eco-hydrologic environment of the Yellow River delta (YRD) in northern China.

Influence of the River Ceasing on Wetland Environment in the Yellow River Delta

Journal of Environmental Science International, 2003
The Yellow River began ceasing affected by natural factors and the unreasonable human activities. The flow broke in the Yellow River and water and sediment flowing into the sea decreased, which lowered the speed of newly formed wetland extending to the sea.

Ecological stoichiometry, salt ions and homeostasis characteristics of different types of halophytes and soils

Frontiers in Plant Science, 2022
Studying eco-stoichiometric and salt ions characteristics of halophytes and soils is helpful to understand the distribution mechanism of nutrients and salts in halophytes and their adaptation strategies to salinized habitats.
