Taiyuan City in the eastern Loess Plateau has experienced severe ecological problems caused by urban expansion. For cities undergoing rapid urbanization, building an security pattern (ESP) is effective means to improve resilience. Here, geographic information systems (GIS) were used analyze, manipulate, and visualize multi-source remote sensing (RS) for history of land use/land-cover (LULC) changes structure system. Four important ecosystem service functions estimated: soil conservation,...

Evaluating the quality and establishing an ecological network are beneficial for maintaining ecosystem health stability optimizing national spatial pattern. This study used morphological pattern analysis (MSPA) remote sensing index (RSEI) to identify sources (ESs) in Shanxi section of Yellow River Basin (SYRB). Comprehensive resistance surface is constructed corrected based on weight. The corridor was identified by Linkage Mapper tool, node barrier points were determined basis minimum cost...

A synthetic flocculant of aluminum (Al) and iron (Fe) extracted from red mud (RM) has been widely used in sewage treatment, while the remaining RM residue ignored. This study aimed to synthesize polymeric ferric sulfate (PAFS) by acid leaching then use acidified produce an RM-based ceramsite (ARMC) mixing bentonite, hydroxypropyl methylcellulose, starch. Our results showed that sintering, reaction temperature, H2SO4 concentration, time, liquid-to-solid ratio had obvious effect on Al Fe RM,...

Roadside soils are regarded as a reservoir for heavy metal pollution, which potentially leads to ecosystem deterioration well serious hazard human health. A comprehensive investigation was conducted the levels, relationship with soil properties, and potential sources of metals (Hg, Cu, Zn, Pb, Cd, Cr) in roadside six cities (Changzhi, Jincheng, Yuncheng, Linfen, Xinzhou, Datong) Shanxi Province; corresponding ecological risk health associated concentrations were addressed. Heavy 112 samples...

Scientific assessment of the development status and factors influencing urban ecological resilience Yellow River Basin (YRB) is highly significant for promoting its development. This study constructed an evaluation index system considering four dimensions pressure, state, response, innovation. The spatiotemporal agglomeration (UA) in Shanxi section YRB from 2012 to 2021 was studied using kernel density estimation, Dagum Gini coefficient, standard deviation ellipse, were analyzed a geographic...

Investigating the evolution of land use and its impact on carbon storage is significant importance for mitigating regional climate change promoting green low-carbon development. Ningwu County located in source region Fenhe Sanggan River, ecological status significantly influences (CS) watershed ecosystem. In this study, PLUS-InVEST model was employed to analyze from 1990 2020 County, Shanxi Province, as well their impacts CS. Additionally, study simulated predicted changes by 2040 under four...

The urban heat island (UHI) effect has intensified with increases in impervious surface areas and population densities due to urbanization, which affects the quality of life ecological services. Here, Moran’s I hot spot analysis (Getis-Ord Gi*) are used explore spatial autocorrelation land temperature (LST) Taiyuan built-up area. Then, area is divided 41 sub-areas accurately LST differences caused by different LULC types. Moreover, geographically weighted regression (GWR) heterogeneity LST....

为了探明达里诺尔湖流域地表水与地下水的氢(H)、氧(O)同位素的变化特征及相互补给关系,于2013年对达里诺尔湖及其周围的河水、井水、泉水中H、O同位素进行了取样分析,并结合总溶解性固体悬浮物(TDS)和区域水文地质对达里诺尔湖流域的补给关系进行讨论分析.结果表明:1) 河水、泉水、井水中H、O同位素的值基本落在全球雨水线上,湖水H、O同位素落在全球雨水线的右下方,说明河水、井水、泉水没有发生蒸发分馏,而湖水则发生较大程度的蒸发分馏;对达里诺尔湖流域地表水与地下水的H、O同位素进行回归模拟,得出该区域的蒸发趋势线方程:δD=4.8753 δ¹⁸O-20.139(n=32,R²=0.9968).蒸发线表明,这些水样具有相同水源的特征.2) 从实地考察发现,泉水补给河水,泉水和河水补给湖水,同时井水、泉水和河水有相似的δD、δ¹⁸O和TDS值,且不随季节变化而变化,推断达里诺尔湖附近地下水补给湖水;区域水文地质条件亦证明达里诺尔湖周边地下水补给湖水.;To examine the characteristics of...

Abstract This study aimed to reveal the characteristics of nutrients and heavy metals associated with ecological risks in sediments Fenhe River, Taiyuan section. The concentrations (total nitrogen, total phosphorus, organic matter) (As, Cu, Zn, Pb, Cr, Ni, Hg, Cd) were investigated. Spatial distribution, correlation analysis source identification facilitated indicate nutrient metal pollution characteristics. Evaluations metals’ contamination degree achieved by comprehensive risk indexes...

To investigate the epidemiological and clinical characteristics of patients with thoracolumbar osteoporotic vertebral compression fracture (OVCF) treated by percutaneous vertebroplasty (PVP).The imaging data 681 OVCF PVP between January 2017 December 2021 were collected. The in single center summarized from aspects demographic distribution (mainly including gender, age), characteristic analysis [including pathological segments, bone mineral density, body mass index (BMI)], operation related...

Stable isotopes have been used to identify the characteristics of precipitation, evaporation, basin hydrology, and residence times. However, lakes in cold regions are usually covered by ice for 5–6 months. To get a better understanding stable indications lake bodies, water were sampled during icebound season both bodies Dali Lake, deuterium, oxygen-18 total nitrogen (TN), major ions analyzed. The results showed that deuterium compositions (δD-δ18O) body greater than beneath, scattered on...

Chlorination has been demonstrated to be an effective method for the prevention and reduction in emitter biological blockage drip irrigation systems. The injected chlorine dose is generally determined by concentration at terminal of laterals which may lead a high residual front system bring detrimental impact soil environment growth crops, especially large units with long laterals. A two-season experiment was undertaken determine effects disinfection lateral length on NO3-N, enzyme...

This study aimed to decipher the influence of red mud on mechanical properties, pore structure, and microstructure basic magnesium sulfate cements (BMSCs). The results showed that BMSC prepared with an appropriate addition exhibited improved properties yielded highest compressive strength 94.54 MPa after curing for 28 days. Adding reduced total porosity optimized structure BMSC. hydration products specimens were examined using X-ray diffraction, scanning electron microscopy,...
