Research BackgroundIn arid desert‑oasis regions, agricultural production and ecosystem stability are highly dependent on limited water resources. While farmland shelterbelts mitigate wind erosion, fix sand and improve field microclimate, they compete for water with adjacent crops and alter soil‑water distribution in nearby farmland. Most existing studies evaluate such impacts based solely on soil water content. Knowledge about water‑uptake sources and their overlap between trees and crops remains limited, making it difficult to interpret shifts in soil microbial functions triggered by water competition. How shelterbelt configurations modify crop water‑uptake sources and further affect microbial osmotic adjustment and carbon metabolism still needs clarification.To fill this research gap, th...

Research BackgroundMoso bamboo (Phyllostachys edulis) is an important species in subtropical forest ecosystems, providing both economic value and ecological functions. However, the long-term cultivation of monospecific moso bamboo forests often leads to constraints on soil nutrient cycling, declining soil fertility, and reduced productivity. In contrast, moso–broadleaf mixed forests can help improve soil conditions, enhance stand stability, and boost productivity. Yet, without effective management, moso bamboo can spread rapidly via rhizomes, altering community structure and inhibiting the reg...

Research BackgroundIn global change research, inland water bodies such as rivers and lakes are not merely conduits for the transport of carbon from land to the ocean; they also serve as critical interfaces for carbon transformation and the release of greenhouse gases. Organic carbon entering these water bodies is partly retained and buried within them, while another portion is converted into CO₂ and CH₄ through microbial decomposition, anaerobic methanogenesis, and gas diffusion, ultimately being released into the atmosphere.In rapidly urbanizing regions, land-use changes, domestic wastewater ...

Research BackgroundUnder the combined influence of global change and human activities, groundwater systems are facing increasingly severe pressures. Particularly in semi-arid regions, uneven spatiotemporal distribution of precipitation, ecological restoration that alters the underlying surface structure, and the substantial vadose zone’s resistance to downward water infiltration have made questions such as “when and how groundwater is recharged, and what the magnitude of that recharge is” central scientific issues. The hilly–gully region of the Loess Plateau is a quintessential ecologically fr...

Against the backdrop of global change, coastal salt marshes are regarded as vital “blue carbon” ecosystems due to their substantial carbon‑sequestration potential. However, over the past three decades, the invasive plant Spartina alterniflora—native to the Atlantic coast of North America—has spread rapidly across China’s coastal salt marshes, continuously disrupting wetland ecological structures and biogeochemical processes, thereby introducing new uncertainties into the blue carbon functions of these ecosystems. Does the expansion of Spartina alterniflora enhance the carbon‑sequestration capa...
