Abstract Concomitant changes of annual precipitation and its seasonal distribution within the context global climate change have dramatic impacts on aboveground net primary productivity ( ANPP ) grassland ecosystems. In this study, combining remote sensing products with in situ measurements , we quantified effects mean MAP PSD spatial variations along a gradient Eurasian temperate grassland. Our results indicated that increased exponentially for entire grassland, but linearly specific type,...
Abstract Understanding ecosystem dynamics and predicting directional changes in response to global are ongoing challenges ecology. Here we present a framework that links productivity state transitions based on spatially continuous dataset of aboveground net primary ( ANPP ) from the temperate grassland China. Across regional precipitation gradient, quantified spatial patterns (variability, asymmetry sensitivity rainfall) related these desert semi‐arid mesic steppe. We show three indices...
Abstract Understanding the atmosphere–land surface interaction is crucial for clarifying responses and feedbacks of terrestrial ecosystems to climate change. However, quantifying effects multiple climatic factors vegetation activities challenging. Using geographical detector model (GDM), this study quantifies relative contributions including precipitation, humidity, solar radiation, air temperature interannual variation (IAV) normalized difference index (NDVI) in northern grasslands China...
Understanding how extreme weather events (EWEs) impact vegetation phenology is crucial for assessing ecosystem stability under climate change. This study systematically investigated the growing season length (GL) response to four types of EWEs- heat, cold, wetness (surplus precipitation), and drought (lack precipitation). The EWEs extremity thresholds were found statistically using detrended long time series (2000-2022) ERA5 meteorological data through z-score transformation. analysis was...
Abstract Predicted future shifts in the magnitude and frequency (larger but fewer) of precipitation events enhanced nitrogen (N) deposition may interact to affect grassland productivity, effects N enrichment on productivity response individual remain unclear. In this study, we quantified addition patterns gross primary (GPP) different sizes ( P size ) a temperate China. The results showed that significantly increased time-integrated amount GPP an event (GPP total N-induced stimulation with...
Abstract Aims Prediction of changes in ecosystem gross primary productivity (GPP) response to climatic variability is a core mission the field global change ecology. However, it remains big challenge for model community reproduce interannual variation (IAV) GPP arid ecosystems. Accurate estimates soil water content (SWC) and sensitivity SWC are two most critical aspects predicting IAV Methods We took widely used Biome-BGC as an example, improve performances temperate grassland ecosystem....
Over the past 50 years, rainfall events have made significant alterations to environments due global warming. The grasslands in arid and semi-arid regions are extremely sensitive variations patterns, which considered significantly affect ecosystem functions. In this study, an experiment with varying sizes frequencies (0 mm, 2 5 10 20 40 mm) was conducted during growing seasons typical grasslands, study effect of changes regime on net exchange (NEE). Our results indicated that NEE exhibited...
Shifting sands are one of the main contributors to desertification in China. This paper briefly reviews measures and techniques which used protect traffic lines by stabilizing fixing desert desertification-affected arid semi-arid areas north We introduce types features these techniques, including mechanical, chemical, biological measures, outline how they have been applied different over past six decades, from 1950s 2010s, taking Baotou-Lanzhou railway, Qinghai-Tibet Tarim Desert highway as...
The estimation of wetland plant biomass is key to understanding the dynamic changes structure and functions ecosystems. Relatively few studies on spatiotemporal dynamics have been conducted because difficulties in obtaining detailed accurate data. Carex cinerascens meadows are important patches Poyang Lake eastern China provide significant food resources habitats for wintering waterbirds, particularly geese. We proposed a method estimate C. subsection Lake, i.e. Baisha employing digital...

Global greening and its relationship with climate change remain the hot topics in recent years, are of critical importance for understanding interactions between terrestrial ecosystem carbon cycle system. China, especially north has contributed a lot to global during past few decades. As water-limited ecosystem, human activities, not precipitation amount, were thought as main contributor China. Considering event characteristics (PEC) altered regimes, we integrated long-term normalized...
Accurately quantifying spatiotemporal variations in evapotranspiration (ET) and its components on Tibetan Plateau (TP) is crucial for understanding the regional water cycle energy balance. However, determinant of spatial ET component processes grassland ecosystems TP remain unclear. In this study, we used 14 sites observation data applied Shuttleworth-Wallace-Hu (SWH) model to investigate relationships between ET, components, influencing factors. Our results highlighted good performance SWH...
Nitrogen (N) and phosphorus (P) additions have led to profound impacts on grassland ecosystems. However, there is currently limited understanding of the response underlying ecological mechanisms ecosystem stability, particularly in relation nutrient inputs their impact resistance resilience. We conducted influence N P resilience a temperate during natural severe drought. Our results demonstrated that addition considerably decreased both community forb, while only forb resistance....
Quantitative assessments of ecosystem service value (ESV) are great significance for rational allocation environmental resources and making regional ecological protection decisions. The method equivalence factor per unit area is widely used this purpose because its simple algorithm. However, ESV also affected by biotic factors (e.g., net productivity (NEP) or precipitation), which difficult to obtain at the scale, leading uncertainty in estimations. In study, according equivalent modified...
