The resource allocation of different component organs crops under drought stress is a strategy for the coordinated growth crops, which also reflects adaptability to condition. In this study, maize variety namely ‘Denghai 618’, ventilation shed, two treatment groups light (LD) and moderate (MD), same rehydration after are set, as well normal water supply control in shed (CS). experiment was conducted jointing–tasseling stage 2021. effects on content biomass each organ were analyzed. results...
The central role of the state and its partners in business as authors football development China has led scholars to foreground institutions, policy, political motivations outcomes. Grassroot expressions culture have generally been sidelined favour analyses politics-business nexus, governance, public health etc, creating impression that is a top-down enterprise driven exclusively by politically connected commercial interests. In this article, we recentre grassroots engagement with examining...
ABSTRACT A large‐scale experimental model of instantaneous dike‐break induced flow was conducted in this work. Water level variations the river channel and floodplain, breach discharge, surface velocity field at were measured during dike failure. The results show that: (i) water rapidly decreased to a minimum (15%–22% initial depth), then began gradually rise, finally approached stable. floodplain increased ultimately tended towards stability. (ii) discharge initially peak, with decreasing...
Drought-flood abrupt alternation (DFAA), characterized by a period of persistent drought followed sudden heavy precipitation at certain level, has significant impacts on ecosystems and socioeconomic environment. As previous studies mainly focused the monthly scale regional scale, our study proposed multi-indicator daily-scale method for identifying DFAA occurrence. Then we applied exploring events over China from 1961 to 2018. The results show that: i) occurred in center southeast China. ii)...
ABSTRACT The fast‐flowing watershed is characterized by rapid runoff and confluence, posing challenges for accurate flood prediction. We introduce three forecasting model structures, namely GRU‐ED, LSTM‐FED, LSTM‐DSA to address this issue. Through application research in representative watersheds, we found that: First, as input information attenuates, the predictive ability of models may decline with an extended lead time. incorporation a feedback mechanism effectively addresses issue,...
Drought-flood abrupt alternation (DFAA) is an extreme hydrological phenomenon caused by meteorological anomalies. To combat the climate change, watershed integrated management model—Soil and Water Assessment Tool model (SWAT)—was used to simulate DFAA, total nitrogen (TN) phosphorus (TP) from 1961 2050, based on measured precipitation data in Hetao area downscaled Representative Concentration Pathways (RCPs) scenarios. In future, increase temperature will aggravate pollution of water bodies....
As basic data, the river networks and water resources zones (WRZ) are critical for planning, utilization, development, conservation management of resources. Currently, network WRZ world most obtained based on digital elevation model data automatically, which not accuracy enough, especially in plains. In addition, code is inconsistent with network, hindering efficiency hydrology research. Based global 90-meter DEM combined a large number auxiliary this paper proposed series methods generating...
Abstract Population and water withdrawal data sets are currently faced with difficulties in collecting, processing verifying multi-source time series, the spatial distribution characteristics of long series also relatively lacking. Time is basic guarantee for accuracy sets, production a realistic requirement to expand application scope sets. Through time-consuming laborious work, this research focuses on population intake interpolates extends them specific land uses ensure demand spatially...
As an essential link between terrestrial and climatic ecosystems, vegetation has been altered by the soil hydrological environment associated with frozen thaw. However, it is not clear whether fluctuating moisture (SM) within zone alters hydrologic to alleviate water stress in plants further, there are scant previous studies at large scale on a threshold for SM greening. This study integrated monitoring data 125 stations from existing studies, then quantified advantages of six remote...
It is of great significance to study the effects and mechanisms key driving forces surface water quality deterioration—climate change LUCC (land use land cover change). The Luanhe River Basin (LRB) in north-eastern China was examined for qualitatively quantitatively assessing responses total nitrogen (TN) phosphorus (TP) loads on different climate scenarios scenarios. results show that from 1963 2017, TN TP basically presented a negative correlation with temperature (except winter), while...
It has become a hot issue to study extreme climate change and its impacts on water quality. In this context, explored the evolution characteristics of drought–flood abrupt alternation (DFAA) total nitrogen (TN) phosphorous (TP) pollution, from 2020 2050, in Luanhe river basin (LRB), based predicted meteorological data representative concentration pathways (RCPs) scenarios simulated surface quality Soil Water Assessment Tool (SWAT) model. The results show that DFAA occurred more frequently...
Soil microbial communities are essential to phosphorus (P) cycling, especially in the process of insoluble solubilization for plant P uptake. Phosphate-solubilizing microorganisms (PSM) dominant driving forces. The PSM mediated soil cycling is easily affected by water condition changes due extreme hydrological events. Previous studies basically focused on effects droughts, floods, or drying-rewetting while few drought-flood abrupt alternation (DFAA), through activities. This study explored...
Based on the VOSviewer software and bibliometric visualization analysis, with 4636 published papers from 2000 to 2021 included in Web of Science (WOS) Core Collection China National Knowledge Infrastructure (CNKI) database, this study reviewed literature effects droughts floods phosphorus through three aspects: publication date, keywords, distribution research discipline, etc. The results show that has risen rapidly recent 20 years, average annual literatures WOS database increased 18.44...
The Ugii Nuur Lake is not only one of the small hydrologically closed lakes located in Orkhon River Basin Central Mongolia but also most vulnerable area for global climate change. Therefore, this study aims to investigate impacts recent change on water surface area. data we analyzed were various measured hydro-meteorological variables lake basin and area, which was estimated from Landsat series satellite 1986 2018. methods used Mann-Kendall (MK), Innovative trend analysis method (ITAM),...
Climate change, especially precipitation will significantly change soil moisture, which then influences root growth, further affecting yield and grain quality. Previous studies focused on the drought or flood effects summer maize growth. However, few studied of drought-flood abrupt alternation (DFAA) growth maize. We explored DFAA impacts roots, leaf area index (LAI), yield, quality in field. The main results show that had different seeding-jointing stage (SJS) tasseling-grain filling (TGS)....
Crop resilience refers to the adaptive ability of crops resist drought at a certain level. When degree stress did not exceed range crop, crop could recover even normal growth after rehydration. However, assessment lacks considerations on mechanisms. Focusing suitable maize planting areas in China, this study took relative soil humidity (RSH) as index screen and rehydration events, identified mechanism under conditions, determined correlation between RSH. The results shown that strongest were...
