Abstract The delivery and distribution of nutrients in coastal wetland ecosystems is much related to the land use. spatial variations TOC, TN, NH 4 + -N, NO 3 − -N TP associated soil salinity with depth 9 kinds uses zone modern Yellow River Delta (YRD) was evaluated based on monitoring data field from 2009 2015. results showed that average contents were 4.21 ± 2.40 g kg −1 , 375.91 213.44, 5.36 9.59 7.20 5.58 591.27 91.16 mg respectively. high N C found cropland southern part low values...
Introduction Sedimentary evolution and river channel changes of large delta (e.g. Huang River, Changjiang River) in response to environmental have been one the key issues global change research. Methods This study reconstructed sedimentary environment modern Yellow River Delta (YRD), based on grain size elemental chemical analysis two short cores (YDC YDG) from southern region Qing 8 course YRD. Results The results indicated that YDC YDG sediment were dominated by silt (58.47% 67.6%,...
Introduction Over the past three decades, approximately 16% of world’s tidal flats have been lost. In Yellow River Delta (YRD), reduction in sediment supply due to decreased discharge has raised concerns regarding morphological stability flats. Methods To investigate response flat development reduced input, a novel physical model experiment was conducted using natural silt from YRD flat. Offshore concentration simulate supply. An Argus system deployed wave basin for first time capture...
The tidal flat is one of the important components coastal wetland systems in Yellow River Delta (YRD). It can stabilize shorelines and protect biodiversity. erosion risk flats wetlands was seldom been studied. Characterizing changes soil particle size distribution (PSD) an way to quantity flats.Based on fractal scale theory network analysis, we determined characterizations (singular dimension multifractal dimension) PSD a successional series YRD eastern China. results showed that major...
Saline–alkali stress is one of the major factors limiting oat seed germination. The regulatory role melatonin (MT) as a naturally occurring active substance well known, but mechanism MT-mediated intrinsic physiological regulation germination under saline–alkali unclear. Therefore, this study investigated (1) variability different MT soaking concentrations and times on seeds stress, (2) possible mechanisms stress. results showed that vigor was significantly reduced oats inhibited; treatments...
Introduction The sediments of the Yellow River delta record environmental changes in basin on a long time scale and are sensitive to river diversion sedimentary environment evolution. Methods In this study, cores YDC YDG near estuary since 1976 were taken as research object, parameterized end-member analysis model was used analyze grain-size data cores. Results results show that: main silty sand (58% 77.9%). parameters showed opposite with wide ranges mixed sizes obviously. End member 1...
Historically, the river course and coastline of Yellow River Delta changed frequently, many studies focused on these change trends their driving forces. Few have explored influence historical channels coastlines response modern landscape patterns. This study examines impact channel migration evolution pattern subdeltas coastal wetlands, utilizing a combination Geo-informatics Remote Sensing images in 1989, 1998, 2009, 2016. The results showed that: (1) Subdeltaic landscapes from 1998 to...

To evaluate the relationship between phosphorus (P) fractions and physicochemical characteristics in soils of estuarine wetlands with different climax vegetation covers, surface 60-cm soil samples were collected Suaeda heteroptera (SH), Tamarix chinensis (TC) Phragmites australis (PA) Yellow River Delta during June 2017. Results showed that inorganic (Pi) PA was significantly lower than TC SH (p < 0.05), organic (Po) opposite pattern, a rank ≫ > SH. The available (AP) had high proportion at...
To cope with the yield loss caused by drought stress, new oat varieties greater tolerance need to be selected. In this study, two different tolerances were selected for analysis of their phenotypes and physiological indices under moderate severe soil stress. The results revealed significant differences in degree wilting, leaf relative water content (RWC), SOD CAT activity between genotypes stress; moreover, drought-tolerant variety exhibited a increase number stomata wax crystals on surface...
Cold waves, as a common natural disaster, have significant impact on economic development and living environment in coastal areas, especially estuary regions. This paper utilizes the Delft3D software based rectangular grid, driven by eight major tidal harmonic constituents of M 2 , S N K 1 O P Q to construct hydrodynamics sediment numerical model. The study focuses morphodynamic changes Yellow River Delta (YRD) during severe cold wave strong wind event. By simulating intense from November 28...
Exogenous melatonin (MT) regulates plant growth and mitigates stress in response to stress. To analyze the machinery of exogenous melatonin, which improves salt alkaline tolerance oats, MT’s function was identified oat seed germination stage our previous study. In this study, morphogenesis, photosynthetic physiology, hormone levels, ion homeostasis were evaluated using same MT treatment concentration. The results revealed that compared S45 treatment, 100 μmol·L−1 efficiently increased...
During the resource crisis, swell energy received an increasing amount of attention due to its stability, huge storage and dominant role in mixed wave. Investigation propagation is beneficial for wave forecasting, monitoring warning so on. However, little research has been conducted on this topic far. The traditional method choose a region advance (short as pre-chosen region) then detect termination region, which limited effectiveness because may not propagate area focused. Based 40-year...
Wang, Q.; Zhong, S. Y.; Li, X. Zhan, C.; Wang X., and Liu, P., 2016. Supratidal land use change its morphodynamic effects along the eastern coast of Laizhou Bay during recent 50 years. Using nautical charts, topographic maps, high resolution remote sensing images field observation, this study analyzed supratidal zone coastal Bay. The results show that bay has been significantly changed in main evolution trend is transition from aeolian sandy land, woodland farmland to aquaculture ponds...
Comprehensive experimental and numerical studies have been undertaken to investigate wave energy dissipation performance main influencing factors of a lower arc-plate breakwater. The model, which considers nonlinear interactions between waves the breakwater, has constructed by using velocity wavegenerating method, volume fluid (VOF) method finite method. results show that relative width, height submergence breakwater are three significant influence on open transmission coefficient is found...
