Characteristics and trends of morphological evolution of the Yangtze subaqueous delta during 1958—2015

open access: yesShui kexue jinzhan, 2018
How the topography of the Yangtze subaqueous delta has evolved in response to sediment decline has aroused wide attention. In order to examine the Yangtze subaqueous delta evolution and influencing factors during the past six decades, bathymetric data ...

Numerical simulation of the effects of Yangtze River runoff on pollutant transport and diffusion in the Yangtze River estuary

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract The coastal-estuary area is one of the areas most seriously affected by human activities, and the quality of the water environment has received extensive attention from society and scholars. In order to analyze the characteristics of pollutant transport in the Yangtze River Estuary, a two-dimensional hydrodynamic model of the ...

Dependence of coastal wetland ecosystem respiration on temperature and tides: a temporal perspective [PDF]

open access: yesBiogeosciences, 2014
Variations in temperature are widely invoked to explain fluctuations in ecosystem respiration (ER), but hydrological conditions also influence ER. Many researchers have observed that aperiodic variations in hydrological conditions affect ER and the ...

Changes in suspended sediments in the Yangtze River Estuary from 1984 to 2020: Responses to basin and estuarine engineering constructions.

open access: yesScience of the Total Environment, 2022
Suspended sediments in the estuary play an important role in regulating the erosion-accretion and shaping the geomorphological patterns. Yet, it can be strongly impacted by the human activities.

The temperature sensitivity of soil organic carbon decomposition is greater in subsoil than in topsoil during laboratory incubation

open access: yesScientific Reports, 2017
The turnover of soil organic carbon (SOC) in cropland plays an important role in terrestrial carbon cycling, but little is known about the temperature sensitivity (Q 10) of SOC decomposition below the topsoil layer of arable soil.

Joint Effect of Spartina alterniflora Invasion and Reclamation on the Spatial and Temporal Dynamics of Tidal Flats in Yangtze River Estuary

open access: yesRemote Sensing, 2020
Tidal flats, which are non-vegetated land–sea transition areas, have an important ecological function in the global ecosystem. However, they have been shrinking in recent years due to natural and anthropogenic activities.

Global forest fragmentation change from 2000 to 2020

open access: yesNature Communications, 2023
A comprehensive quantification of global forest fragmentation is urgently required to guide forest protection, restoration and reforestation policies. Previous efforts focused on the static distribution patterns of forest remnants, potentially neglecting
