Abstract Terrestrial ecosystems can exhibit various behaviors in response to climate change and human activities. Nonlinear abrupt shifts are particularly important as they indicate substantial modifications ecosystem structure function, posing a threat the provision of services. Here we distinguish between linear, curvilinear, productivity from 2000 2020 China's Loess Plateau. We utilize spatial Random Forest models analyze driving factors behind these patterns. Our findings that 84.1%...
Abstract. Satellite observations of evapotranspiration (ET) have been widely used for water resources management in China. An accurate ET product with a high spatiotemporal resolution is required research on drought stress and management. However, such currently lacking. Moreover, the performances different estimation algorithms China not clearly studied, especially under environmental conditions. Therefore, aims this study were as follows: (1) to use multisource images generate...
Net primary productivity (NPP) of terrestrial ecosystems serves as a crucial carbon sink, playing significant role in mitigating climate change. This study, focusing on the Yangtze River Economic Belt (YREB), key area for both economic development and ecological conservation China, evaluates temporal spatial changes regional NPP its responses to climatic factors against backdrop global Utilizing long-term meteorological grid data from 1981 2017, we analyzed annual change patterns linear...
The discharge of Fukushima radioactively contaminated water into the Pacific Ocean started in August 2023, posing comprehensive threats to marine ecosystems and human health globally. This study introduces Contaminated Water Risk Factor (FCWRF), which integrates three components─radionuclide diffusion, bioaccumulation, global seafood trade─to evaluate spatiotemporal distribution risks based on actual practices. Results suggest that exceeding 2 orders magnitude beyond baseline will be...
Experimental investigations were carried out to study the effect of pyrolysis temperature on characteristics, structure and total heavy metal contents sewage sludge biochar (SSB). The changes in chemical forms metals (Zn, Cu, Cr, Ni, Pb Cd) caused by analyzed, potential ecological risk (SSB) was evaluated. conversion into reduced H/C O/C ratios considerably, resulting stronger carbonization a higher degree aromatic condensation biochar. Measurement results showed that pH specific surface...
In this study, chalcopyrite was oxidized in hydrogen peroxide (H2O2) solutions of different concentrations to simulate degrees oxidation real ores, and the effects H2O2 treatment on surface properties flotation performance were investigated by analysis techniques floatation experiments, which implied reason for poor grade recovery concentrate production process ore. Flotation results showed that when concentration increased from 0% (by weight) 5%, decreased sharply. However, with increasing...
The rapid development of the social economy and continuous change in land use have greatly altered ecological risk regional landscape. This study focused on Yangtze River Basin China aimed to examine temporal spatial variation characteristics landscape (LER) over a period 34 years (1982–2015), after determining optimal sub-watershed scale. Based conditional probability framework, non-linear response NPP LER was revealed. Finally, primary driving factors were explored, additional potential...
Abstract Clipping management, which alters vegetation conditions by removing aboveground while preserving the underground root system, directly impacts hydrological processes and flow dynamics, ultimately affecting soil erosion processes. This study conducted field experiments (2 × 6 m) encompassing four clipping intensities (with coverage of 70%, 50%, 25%, 0%), three rainfall (60, 90, 120 mm·h −1 ), slope gradients (10°, 20°, 30°). The results showed that treatments significantly reduced...
E-commerce sellers are recommended keyphrases based on their inventory which they advertise to increase buyer engagement (clicks/sales). Keyphrases must be pertinent items; otherwise, it can result in seller dissatisfaction and poor targeting -- towards that end relevance filters employed. In this work, we describe the shortcomings of training filter models biased click/sales signals. We re-conceptualize advertiser keyphrase as interaction between two dynamical systems Advertising produces...
We introduce a novel Rayleigh Doppler lidar (RDLD) system that utilizes high-power single-frequency laser with over 60 W average output power, achieved through fiber solid-state cascade amplification. This represents significant advancement by addressing common challenges such as mode hopping and multi-longitudinal issues. Designed for atmospheric wind temperature profiling, the operates effectively between altitudes of 30 km 70 km. Key performance metrics include speed measurement errors...
