Mapping and Analyzing the Spatiotemporal Patterns and Drivers of Multiple Ecosystem Services: A Case Study in the Yangtze and Yellow River Basins

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(2), P. 411 - 411

Published: Jan. 20, 2024

The Yangtze River Basin (YZRB) and the Yellow (YRB), which are crucial for ecology economy in China, face growing challenges to ecosystem service (ES) functions due global population growth, urbanization, climate change. This study assessed spatiotemporal dynamics of ESs YZRB YRB between 2001 2021, comprehensively encompassing essential aspects such as water yield (WY), carbon sequestration (CS), soil conservation (SC), habitat quality (HQ) while also analyzing trade-offs synergies among these at grid cells. GeoDetector was employed ascertain individual or interactive effects natural anthropogenic factors on their trade-offs/synergies. results showed that (1) from four exhibited significant spatial disparities distribution within two basins, with overall trend mainly increasing. consistently substantially higher ES values than YRB. (2) Complex were apparent both characterized by distinct heterogeneity. relationships WY–CS, WY–SC, CS–SC, CS–HQ synergistic. (3) Precipitation, potential evapotranspiration, elevation, land use cover (LULC), slope influenced basins. Notably, factors, particularly interactions involving LULC other demonstrated more robust explanatory power trade-offs/synergies drivers. These findings significantly affect refined management sustainable development decision-making large rivers regions.

Spatial and temporal divergence and driving mechanisms of carbon sinks in terrestrial ecosystems in the middle reaches of the Yangtze River urban agglomerations during 2008–2020

Ecological Indicators, Journal Year: 2024, Volume and Issue: 165, P. 112205 - 112205

Published: June 4, 2024

Urban cluster carbon sinks are key parts of the terrestrial cycle, and play an important role in global climate change. Based on inversion results net ecosystem productivity (NEP) Middle Reaches Yangtze River Agglomeration (MRYRUA), this study considered influence both natural environmental socioeconomic factors NEP, investigated driving mechanism sink emphasizing spatial temporal heterogeneity by geographically temporally weighted regression model (GTWR). Results demonstrated that (1) During 2008–2020, annual average NEP was positive MRYRUA, effect increased. (2) In Precipitation DEM were positively correlated with sinks, opposite for temperature, percentage water areas population density. (3) period, factors, such as temperature precipitation grew gradually weaker, whereas The urbanization rate, night lights index industrial structure changed from negative to positive, while built-up area had increasing NEP. conclusions above, proposed differentiated policy implications, including improving vegetation hydrothermal environment, controlling urban expansion accelerating transformation. It would provide empirical inspiration attaining peak carbon, neutrality, sustainable development goals.

Groundwater Storage Response to Extreme Hydrological Events in Poyang Lake, China’s Largest Fresh-Water Lake

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(6), P. 988 - 988

Published: March 12, 2025

Groundwater systems are important for maintaining ecological balance and ensuring water supplies. However, under the combined pressures of shifting climate patterns human activities, their responses to extreme events have become increasingly complex. As China’s largest freshwater lake, Poyang Lake supports critical resources, health, adaptation efforts. Yet, relationship between groundwater storage (GWS) hydrological in this region remains insufficiently studied, hindering effective management. This study investigates GWS response by downscaling Gravity Recovery Climate Experiment (GRACE) data validating it with five years observed daily levels. Using GRACE, Global Land Data Assimilation System (GLDAS), ERA5 data, a convolutional neural network (CNN)–attention mechanism (A)–long short-term memory (LSTM) model was selected downscale high resolution (0.1° × 0.1°) estimate recovery times return baseline. Our analysis revealed seasonal fluctuations that phase precipitation, evapotranspiration, runoff. durations flood (2020) drought (2022) ranged from 0.8 3.1 months 0.2 4.8 months, respectively. A strong correlation meteorological droughts, while agricultural significantly weaker. These results indicate precipitation runoff more sensitive than evapotranspiration influencing changes. findings highlight significant sensitivity GWS, despite improved management
