The Relationship Between Human Activities and Ecosystem Service Supply–Demand From the Perspective of Land Use Transformation

Land Degradation &Development, EarlyView.
ABSTRACT The equilibrium between ecosystem service supply and demand relationships (ESSDR) is essential for regional sustainable development. Understanding the relationship between human activity intensity (HAI) and ESSDR from the perspective of land use transformation (LT) is important for ecological management and governance.

Iron/Manganese Oxide‐Bound Nitrogen Suppresses Microbial Mediated Nitrate Reduction in Soil

Land Degradation &Development, EarlyView.
ABSTRACT Nitrogen cycling plays a pivotal role in sustaining ecosystem productivity and stability, while the chemical forms of nitrogen in soils critically influence both its efficiency and pathways. In this study, farmland soils from the Anning River Basin—an important watershed in Southwest China—were investigated to examine the regulatory effects of

Environmental magnetic records of PETM in the southwestern Sichuan Basin [PDF]

Chinese Science Bulletin, 2018
Collision between the Indian and Eurasian plates produced concomitant uplift of the Tibetan Plateau and its basin-ridge geomorphological systems. As the world’s largest and highest plateau, Tibetan Plateau surface relief has significant dynamic and thermal effects on atmospheric circulation and on regional and global climate.

Assessing Soil Erosion in a Typical Karst Region: A Model Improved by Bedrock Exposure Rate in Guizhou Province

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion is a major environmental challenge in karst regions of Southwest China, where thin soils and high bedrock exposure accelerate land degradation. This study modified the RUSLE model by incorporating bedrock exposure rate to improve erosion simulation in Guizhou Province from 2000 to 2024.

Integrating Ecosystem Service Benefits to Assess Ecosystem Health and Its Response to Land Spatial Structure Conflicts in Anning River Basin, China

Land Degradation &Development, EarlyView.
ABSTRACT Land spatial structure conflicts (LSSC) weaken the actual benefits of ecosystem services by inducing trade‐offs among them, directly threatening regional ecosystem health (EH) and sustainable development. However, most studies have failed to incorporate ecosystem service benefits (ESB) into EH assessments and have overlooked their response to ...

From Past to Future: Overall Patterns, Nonlinear Relationships, Spatial Heterogeneity and Drivers of Ecosystem Service Trade‐Offs and Synergies in the Yangtze River Economic Belt

Land Degradation &Development, EarlyView.
ABSTRACT Land‐use change and climate change are reshaping watershed ecological functions and may intensify the risk of localized ecological degradation. However, existing studies have primarily focused on the spatiotemporal patterns of ecosystem services (ESs) during historical periods, while the nonlinear changes, spatial heterogeneity, and driving ...

Development and Validation of a Questionnaire‐Based Model for Households With Multiple Helicobacter pylori Infections: A Family‐Based Screening Strategy

Med Research, EarlyView.
This study developed and externally validated a questionnaire‐based household risk model to identify families with multiple Helicobacter pylori infections. Using only noninvasive, readily available household information, the model showed good discrimination and enabled a family‐based screening strategy that substantially improved detection efficiency ...

Genesis and Geological Significance of Tuff in the Wujiaping Formation, Upper Permian, Northern Sichuan Basin, China

Geosciences
In the northern Sichuan Basin, distant from the main body of the Emeishan Large Igneous Province (ELIP), marine deposits of the Wujiaping Formation from the Permian period contain widely distributed tuffs of varying thicknesses. To clarify the genesis of

Preliminary Assessment of Methane Concentration Variation Observed by GOSAT in China

Advances in Meteorology, 2015
Atmospheric column-averaged methane (XCH4) observations from GOSAT are analyzed to study the spatiotemporal variation of XCH4 in China. Furthermore, we investigate the driving mechanism of XCH4 spatiotemporal variations, especially for high XCH4 values ...
