Coastal wetlands are vital ecosystems at the land–sea interface. They intercept land-based pollutants, regulate microclimates, and mediate carbon cycles. play a significant role in enhancing sequestration capacity maintaining ecological structure functioning. This study proposes an improved method for estimating blue storage coastal salt marsh wetlands, considering soil thickness, by utilizing enhanced Soil Land Inference Model (SoLIM) to estimate thickness with restricted number of sample...

An accurate diagnosis is important for the medical treatment of patients suffering from brain diseases. Magnetic resonance (MR) images are commonly used by technicians to assist preclinical diagnosis. The classification MR normal and pathological brains poses a challenge technological point view, since imaging generates large information set that reflects conditions brain. In this paper, we present computer‐assisted method based on wavelet entropy (WE) feature space approach feed‐forward...

Abstract Natural wetlands along the coasts of Yellow and Bohai Seas provide key stopover sites for migratory waterbirds. However, these are facing land loss. Understanding how natural wetland loss influences habitat is important management. We used species distribution models to report changes in area suitable analysed effects on 80 waterbird four functional categories (shorebirds, ducks, herons, gulls) between 2000 2015 beside Seas. Between 2015, 1794.8 km 2 (29.27%) coastal was lost...

The carbon sink of cultivation shellfish in coastal wetlands is characterized as both highly ecological and economic value, thus making great contributions to achieving neutrality. In this study, the main species cultured ( Ruditapes philippinarum , Meretrix meretrix Sinonovacula constricta Scapharca suberenata Grassostrea gigas ) were selected research objects wetland Yalu River Estuary measure yields contents. Combined with data from fishery statistics Donggang city, Dandong, Liaoning...

Coastal wetlands are important areas with valuable natural resources and diverse biodiversity. Due to the influence of both factors human activities, landscape coastal undergoes significant changes. It is crucial systematically monitor analyze dynamic changes in wetland cover over a long-term time series. In this paper, series remote sensing classification process was proposed, which integrated feature selection sample migration. Utilizing Google Earth Engine (GEE) Landsat TM/ETM/OLI image...

It is of great importance to early detect abnormal brains, in order save social resources.However, potential wavelet decomposition not fully explored and widely used.The wavelet-energy was a successful feature descriptor that achieved excellent performance various applications; hence, we propose based new approach for automated classification MR human brain images.The consisted three-stage system, including decomposition, energy extraction, support vector machines.The results proposed showed...

Water table affects litter decomposition in wetlands, but its effects on the degradation of cellulose and lignin are poorly understood. We performed a experiment Poyang Lake Wetland, to determine how water affected lignin. After 60 days at site with relatively highly table, 46.19% initial 41.95% remained. Decay rates both increased as depth increased. Principle component analysis showed that decay increasing soil pH, decreased contents clay fungi: bacteria ratio. The path model accounted for...

The composition and functional traits of plant communities their changes along an environmental gradient are important bases for maintaining the carbon sinks estuarine wetlands. To clarify succession pattern community in estuary gradient, this study considered Liaohe Estuary wetland as research object divided dominant into a Phragmites australis high-, medium-, low-density Suaeda salsa communities. We employed redundancy analysis, variance decomposition, multiple regression to examine impact...

From November 2016 to April 2017, the decomposition of Carex. cinerascens Kükenth litter along natural gradients groundwater level at Poyang Lake wetland beach were simulated using litterbag technique. The depth underground water table G-L was −25 −50 cm, while those G-ML, G-MH and G-H ranged from −15 −5 5, respectively. Additionally, dry weight loss rate increased gradually with increasing days, that being highest, followed by G-MH, G-ML G-L. four rapidly day 30, then decreased slowly until...

Through variance decomposition, we investigated the impact of rate development and utilization intensity coastal areas economic industrial structure spatial location on environmental quality seawater. The water Liaodong Bay waters was evaluated using comprehensive evaluation index, Nemerow principal component analysis. Dalian Huludao were found to have significantly better than Panjin, Yingkou, Jinzhou near Liaohe Estuary. Marine functional seawater index spatially correlated, sea area had a...

The contradiction between the development of marine resources and ecological protection in Zhejiang is prominent, which restricts high-quality continuous supply products. As a result, efficient maintenance security pattern inshore waters relies on scientific division function zones management zoning areas. This paper constructs technical framework for from aspects ecosystem health, diversity economic social balance using GIS-based overlay analysis three-dimensional matrix discriminant model...

以鄱阳湖典型碟形湖泊——白沙湖为监测对象,开展水体有机碳(TOC)、总氮(TN)、铵态氮(NH₄⁺-N)和硝态氮(NO₃^--N)浓度的年内动态变化的定位观测,结合在白沙湖开展的灰化薹草(Carex cinerascens)分解模拟实验和稳定同位素示踪技术,对薹草分解过程和水体营养盐浓度变化进行时间匹配,分析水体中颗粒态有机物(POM)的来源,并探讨水位变化和薹草分解对水体营养盐浓度的交互作用.结果表明,水体TOC、TN和NH₄⁺-N浓度在枯水季14月明显高于其他月份;薹草在0~60...

(Aim) It is of great importance to find abnormal or pathological brains in the early stage, save hospital and social resources. However, potential wavelet-energy not widely used this field. (Method) The popular "wavelet-energy" regarded as a prevalent feature descriptor, which achieves good performance many applications. In work, we propose based new method for classification magnetic resonance brain images. approach three-stage system, including wavelet decomposition, energy extraction,...

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...

Scientifically evaluating ecological restoration effectiveness is crucial for ensuring stable improvement of estuary wetland ecosystems. Restoration modules were developed water–salt environment, plant community structure, and functional trait. The results show that the structure traits soil habitat exhibit significant trends after measures are implemented. During restoration, was gradually restored to level in undamaged areas, biomass increased by a factor 329, carbon content 1.32, salinity...
