Local and Tele‐Coupling Coordination Relationships Between Urban Resilience and Ecosystem Health in the Beijing‐Tianjin‐Hebei Region and Analysis of Their Influencing Factors

Land Degradation &Development, EarlyView.
ABSTRACT Urban resilience and ecosystem health are essential foundations for regional sustainable development, yet their coupled and coordinated relationships remain insufficiently explored at the urban‐agglomeration scale. Taking the 13 prefecture‐level cities in the Beijing‐Tianjin‐Hebei urban agglomeration as the study area and using panel data for ...

Constructed Wetlands as Remediation Tools for Shallow Groundwater Contaminated by Swine Lagoon Seepage

, 2005
Swine waste is typically flushed from beneath confinement houses into anaerobic lagoons for temporary storage and partial treatment. When improperly constructed, studies have shown that there is potential for the high strength wastewater to leak from the

Afforestation Partially Offsets Losses of Soil Conservation Services and Carbon Stock From Direct and Indirect Urban Expansion in China

Land Degradation &Development, EarlyView.
ABSTRACT Urban expansion has exerted both direct and indirect impacts on natural land and ecosystem services it supports, driven by increasing population and food demand, yet these underlying pathways remain insufficiently distinguished. Here, we quantified the losses of soil conservation services (water erosion regulation and sandstorm prevention) and

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, EarlyView.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

Spatiotemporal Interactions of Land Use Change, Land Surface Temperature, and Vegetation Dynamics in China's Caohai National Nature Reserve

Land Degradation &Development, EarlyView.
ABSTRACT Understanding the spatiotemporal dynamics of land use change (LUC), land surface temperature (LST), and vegetation indices is critical for assessing ecological changes and informing sustainable land management. This study investigates the long‐term interrelationships between LUC, LST, and vegetation indices in China's Caohai National Nature ...
