Abstract Designing heterogeneous interface to enhance the kinetics for electrocatalysts is a highly efficient but challenging pathway toward hydrogen evolution reaction (HER) in water electrolysis. Herein, coupling of CeO 2 quantum dots onto porous Ru aerogel through interfacial Ru‐O‐Ce bridge proposed construct ‐Ru as superior HER electrocatalyst with ultra‐low overpotentials. In situ characterizations and theoretical calculations reveal electron distribution at boost bonding sites, faster...
The anomalies of cadmium (Cd) in karst region pose a severe threat to plant growth and development. In this study, the responses Rhododendron decorum Cd stress were investigated at physiological, molecular, endophytic microbial levels, potential correlation among these was assessed. impeded R. led an increase malondialdehyde (MDA) hydrogen peroxide (H
Research into global water resources is challenged by the lack of ground-based hydrometric stations and limited data sharing. It difficult to collect good quality, long-term information about river discharges in ungauged regions. Herein, an approach was developed determine 24 rivers regions on Tibetan Plateau a scale. This method involved coupling Manning–Strickler formula, from unmanned aerial vehicle (UAV) Gaofen-2, SPOT-5, Sentinel-2 satellites. We also compared calculated using three...
River discharge is of great significance in the development water resources and ecological protection. There are several large ungauged catchments around word still lacking sufficient hydrological data. Obtaining accurate information from these areas an important scientific issue. New data methods must be used to address this In study, a new method that couples unmanned aerial vehicle (UAV) with classical slope–area developed calculate river discharges typical catchments. UAV obtain...
Ephemeral rivers are vital to ecosystem balance and human activities as essential surface runoff, while convenient effective ways of calculating the peak discharge ephemeral scarce, especially in ungauged areas. In this study, a new method was proposed using an unmanned aerial vehicle (UAV) combined with incipient motion stones calculate northwestern China, typical arid region. Two field surveys were conducted dry seasons 2017 2018. Both logarithmic exponential velocity distribution methods...
The Tianshan Mountains, known as the “water tower” of Central Asia, are major source water for most part Xinjiang and oasis region Asia. However, climate warming has amplified discharges glacial meltwater in Mountains. In this study, we calculated river discharge by integrating cross-sections mapped using unmanned aerial vehicles (UAV) velocity data collected field. Multiple remote sensing images, such Landsat Sentinel-2 imagery, were applied to estimate long-term 19 sections ungauged...
The transport characteristics of phosphorus in soil and the assessment its environmental risk have become hot topics agricultural fields. Sanjiang Plain is an important grain production base China, it characterised by serious land use change caused large-scale exploitation. Agricultural inputs tillage management destroyed nutrient balance formed over long-term conditions. There are few studies on non-point source pollution Plain, which largest swampy low plain a mid-high-latitude region...
Most of the terminal lakes in inland basins, which account for half world's lake reserves, have been shrinking at an alarming rate recent years. In a Terminal Lake Basin, changes water level can lead to variations local erosion base level. From perspective level, we revealed response river evolution change Ebinur Basin past 5000 Our results verified three geomorphic development stages natural decline, balance maintenance, and imbalanced decline. modern times, decline number rivers entering...
Obtaining the water volume of small- and medium-sized lakes in enclosed watersheds with scarce data is a global focus research. River flow into lake an important factor affecting volume. However, most river measurement methods involve long cycles, low efficiency, transdisciplinary expertise, making rapid assessments ungauged basins impossible. This paper proposes remote sensing estimation method based on multi-source data, which quickly assesses provides input for simulation. The...
Global climate change, especially the snow drought events, is causing extreme weather events influencing regional vegetation growth and terrestrial ecosystem stability in a long-term persistent way. In this study, Sanjiang Plain was selected, as area has been experiencing past two decades. Logistic models, combined with multisource remote sensing unmanned aerial vehicle (UAV) data, well meteorological data over 20 years, were used to calculate sixteen phenological periods biomass. The...
河道流量的获取是水资源开发及生态保护的基础。但在缺少资料地区,如何方便、准确的获取流量资料仍然是一个难题。随着无人机航空摄影测量的发展,为解决该问题提供了新的数据源和思路。本研究利用无人机航空摄影获取的高精度的DOM(Digital Orthophoto Map)与DSM (Digital Surface Model),结合经典曼宁公式河道流量算法,深度挖掘航测数据记录的地表高程信息,提出了一种河道流量估算的新方法。研究计算了中国西北典型无资料区准格尔盆地的卡赞营、博尔通古、安集海、大河沿子和二叉河等5个典型断面的流量。与实测流量对比分析得出如下结论:5个计算断面流量平均相对误差为10.74%,最小相对误差为1.43%,均方根误差RMSE(Root Mean Squared Error)为4.82 m3/s,平均百分比误差MPE(Mean Percentage...
The Pamir Plateau is an extremely important water resource area for over 60 million people in Central Asia. With the increasingly significant response of resources to climate change, timely hydrological predictions future supply are necessary. In plateau, accessing and monitoring glaciers their melt outflow challenging due harsh geographic environments. Unmanned aerial vehicles (UAVs) combined with remote sensing technologies offer great potential providing information improve management...
Nonpoint source pollution (NPSP) is a serious environmental problem faced by megacities throughout the world.Unlike small cities, problems associated with NPSP are more complex in developing megacities.However, long-term spatial and temporal variations NPSP, as well driving forces behind these changes, still unknown for megacity.In this study, we used model set containing export coefficients statistical models to calculate load five types from 2006 2016 Beijing its four city functional...

With the development of human society, balance between minimum ecological instream flow requirement (MEIFR), which is an essential part water demand in arid areas, and anthropogenic depletion has received increasing attention. However, due to lack hydrological station data river information on basins, previous researchers usually considered only individual rivers, lakes, or oases. To address this issue, a new method that combines hydraulic parameters wet circumference obtained by unmanned...
