Research BackgroundThe hydrological processes of plants in forest ecosystems of arid regions are an essential component of regional water cycles. They not only influence community structure, ecological functions, and productivity but also affect the regional balance of matter and energy. As the primary source of water input into arid ecosystems, precipitation exhibits significant seasonal variability and limited temporal availability. The coniferous forests at the northern foothills of the Tianshan Mountains represent a typical cool-temperate forest characterized by relatively abundant rainfal...

Research BackgroundIn karst regions, the soil layer is shallow and bedrock is often exposed. Groundwater distribution varies significantly across different soil layers and rock fractures, making water availability a critical factor limiting vegetation restoration and long-term stability. Limestone and dolomite differ markedly in terms of weathering degree, soil thickness, and fracture structure, which may further influence plant root water uptake, xylem water transport, and leaf transpiration processes. However, existing studies have largely focused on the impacts of climate or vegetation type...

Against the backdrop of global change, the water cycle is being reshaped. How does precipitation enter the soil? How is soil water absorbed by plants? Does deep soil water contribute to groundwater recharge? These questions may seem disparate, yet they all point to the same critical medium—the soil water.Recently, the team led by Professor Zhu Guofeng from Northwest Normal University published a data paper in Scientific Data, presenting and releasing a global-scale dataset of stable isotopes in soil water. This dataset systematically integrates observations of stable hydrogen and oxygen isotop...

Research BackgroundGlobal warming is accelerating the degradation of permafrost in high-altitude cold regions and is also altering the way rivers receive water. The Qinghai-Tibet Plateau is the world’s largest and highest-altitude permafrost region, as well as an important source area for numerous rivers. As the active layer of permafrost deepens and seasonal freeze-thaw processes intensify, the connections among surface water, soil water, and groundwater are being reshaped, leading to changes in the sources of river runoff. Previous studies have shown that precipitation, snowmelt, soil water,...

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 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...
