96 t·d-1 (2036.89 t·d-1), -1171.09 t·d-1 (-1879.12 t·d-1), and 411.87 t·d-1 (157.77 t·d-1), respectively, indicating that PM2.5 inputs from surrounding cities per unit time were higher than external inputs to the surrounding cities. Furthermore, net PM2.5 flux showed notable vertical evolution; the total net flux of PM2.5 in Beijing and Shijiazhuang below 1782 m ranged from 17.86 to 64.18 t·d-1 and -2.95 to 134.81 t·d-1, respectively, and both peaked 817 m above the ground at 64.18 and 134.81 t·d-1. Moreover, a significant increase the net PM2.5 inflow flux in Zhangjiakou and Shanxi explained the observed net flux peaks in these two cities.Regional meteorological conditions and emissions reduction are closely related to air quality. China has a monsoonal climate and regional meteorological conditions are significantly impacted by interannual climate variability. The objective of this study was to evaluate the contributions of meteorological conditions and emissions reduction to regional improvements in air quality. Trend analyses of key meteorological factors and air pollution for the Beijing-Tianjin-Hebei region, Chengdu-Chongqing region, Yangtze River Delta, and Pearl River Delta urban agglomeration areas were performed for the period from 2001 to 2018, and K-Nearest Neighbor (KNN) models were constructed for each calendar year. The analysis showed that approximately half of the years between 2001 and 2018 experienced abnormal global-scale climate conditions, i.e., El Niño and La Niña. Both emissions reduction and climate changes contributed to the improvement of air quality during the study period. The contribution of meteorological conditions to air quality improvement under abnormal climate conditions was 51% compared to 30% under normal climate conditions in the Beijing-Tianjin-Hebei region; for the Yangtze River Delta and Pearl River Delta regions, meteorological conditions contributed approximately 50% to the improvement of air quality under both abnormal and normal climate conditions. In addition, the contribution of emissions reduction to air quality improvement was higher in the study areas during 2015-2018 compared to 2001-2012. This indicates that emissions reduction has played an increasingly important role in air quality improvements largely due to the implementation of a variety of emission control measures. However, the contribution of meteorological conditions to air quality improvement cannot be ignored.To evaluate the health benefits brought about by air environmental treatment and determine the main drivers of health risk, we calculated the health and economic benefits attributed to PM2.5 control in Eastern and Central China from 2013 to 2017 by combining PM2.5 concentrations with a human activity enhanced exposure-response model. The relative contributions of changes in four factors related to the PM2.5 health burden were also quantified, namely total population, population aging, baseline mortality rates, and ambient exposure. The results show that the population weighted PM2.5 concentration decreased by 28.73% and the proportion of the population exposed to annual PM2.5 concentrations lower than or equal to 35 μg·m-3 increased from 11.23% to 27.91% across the study area during this period. Avoided deaths were decreased to 14.43%, which equates to avoided economic losses of approximately 559 billion RMB. If PM2.5 concentration meets the Chinese Ambient Air Quality Standard Grade Ⅱ (35 μg·m-3) or Grade Ⅰ (15 μg·m-3), or the World Health Organization Air Quality Guidelines (AQG) standards (10 μg·m-3), a 8.22%, 55.05%, and 79.36% reduction in the total deaths could be achieved in the base year (2017) with equivalent total economic benefits of approximately 319, 2137, and 3081 billion RMB, respectively. Total population, population aging, baseline mortality rates, and PM2.5 concentrations contributed -2.69%, -12.38%, 1.66%, and 14.57% to PM2.5-related deaths. Overall, during the study period, the reduction in PM2.5 concentrations has been the main factor contributing to the reduction in the public health burden. China has implemented significant air pollution control measures; however, the health burden associated with high PM2.5 concentrations in densely populated areas is still extremely high, requiring an aggressive air pollution control strategy.A scientific performance evaluation of the regional water ecological civilization construction and clarifying the obstacle factor are key points to improve the performance of regional water ecological civilization construction theory. This study analyzes the coupling relationship between humans and regional water ecology by applying the thinking logic of "driving force-pressure-state-influence-response-management." The regional water ecological civilization construction performance evaluation index system based on the DPSIRM model was established. Combining the unascertained measurement model and obstacle diagnosis model, the water ecological civilization construction performance of Shizuishan City during the past 10 years was empirically evaluated, and the obstacle factors affecting local construction performance were diagnosed and analyzed. The analytical results reveal the following pointsFirst, the performance of the water ecological civilization construction in Shizuishan City gradually increased annuallnsumption per ten thousand yuan of value-added by industry as a representative subsystem are the key directions to future construction. In this paper, the concepts and methods of the research can provide a theoretical reference for the performance evaluation of regional water ecological civilization construction and its obstacle factor diagnosis analysis.Increasing antibiotic resistant genes (ARG) are being detected in animal manure-amended soil, causing public concerns. However, the effects of animal manure fertilization on the ARG of vegetable endophytes remain unknown. In this study, high-throughput quantitative PCR (HT-qPCR) was used to explore the effects of poultry manure fertilization on the bacterial community and resistome in the soil, root endophytes, and leaf endophytes from Cichorium endivia L.. The results indicated that poultry manure fertilization not only enhanced the number of ARG in soil and root endophytes, but also increased the abundance of ARG in the soil, root endophytes, and leaf endophytes. The relationship analysis demonstrated that the ARG profile in the soil and vegetable endophytes was significantly correlated with the bacterial community, and the ARG abundance was highly correlated with Proteobacteria, Acidobacteria, Actinobacteria, and Cyanobacteria. In addition, the overlapping ARG between the Cichorium endivia L. endophyte and soil indicated the internal spread route of the ARG from the manure to Cichorium endivia L through the soil. In conclusion, poultry manure fertilization increased the diversity and abundance of the ARG in vegetables via the manure-soil-vegetable pathway.Sandy soils are considered as a significant transition phase to desertification. The effective recovery of sandy soils is of great significance to mitigate the desertification process. Some studies have shown that arbuscular mycorrhizal (AM) fungi and biochar improved the sandy soil, but there have been very few studies regarding the combined effects of AM fungi and biochar amendments on sandy soil improvement. Additionally, the roles of the bacterial and fungal community during the process of sandy soil improvement remain unclear. A greenhouse pot experiment with four treatments, including a control (CK, no amendment), single AM fungi-assisted amendment (RI), single biochar amendment (BC), and combined amendment (BC_RI, biochar plus AM fungi), was set up. This study investigated the effects of different amendment methods on the Nitrariasi birica mycorrhizal colonization, biomass, nutrient (N, P, K, Ca, and Mg) content, soil organic carbon, soil nutrient (TN, TP, and TK) content, and soil water-stable aggregaoration of sandy soils under the combined AM fungi and biochar amendment.Soil fungal communities are reconstructed under heavy metal stress. This study was conducted to explore the structural and functional diversity of soil fungal communities under different land-use patterns, namely grassland and farmland, in 15-year-old or 10-year-old poplar plantations (Populus deltoides cv. 'zhonghuahongye') near the Shibahe copper tailing dam and the surrounding area, located in Yuanqu County, Shanxi. The results indicated that the abundance and diversity of fungal communities were the highest in the 15-year-old poplar plantation and lowest in the grassland on the tailing dam. The dominant fungal groups in the study area were Ascomycota, Basidiomycota, and Mortierellomycota. The Ascomycota members were the most abundant at all four sampling sites, reaching 92.92% of the fungal community in the grassland on the tailing dam. The highest functional diversity of carbon utilization was found in the soil fungal communities of the 15-year-old poplar plantations; moreover, the diversity in the grassland on the tailing dam was significantly higher than that in the farmland and in the 10-year-old poplar plantation. Meanwhile, we also observed the highest glucoside carbon source utilization efficiency in the grassland. Notably, the correlation analysis revealed that Ascomycota was significantly correlated with the utilization efficiency of the glucoside carbon source in our study area. Moreover, the soil total nitrogen content, but not the soil heavy metal content, was significantly correlated with the abundance of the soil fungal community. There were significant correlations between the cadmium and arsenic contents and the soil fungal community diversity indices. Our results indicated that the soil fungal communities were more influenced by soil fertility and land use than by the soil heavy metal content. This study underlies the application of soil fungal communities in soil remediation of heavy metal-contaminated areas.A pot experiment was carried out to study the impacts of five organic materials (rape straw, broad bean stalk, peat, pig manure compost, and biochar) on the availability of arsenic (As) and cadmium (Cd) in soil, the amount of iron plaque on the root surface, as well as the uptake and translocation of As and Cd in rice grown in an As/Cd co-contaminated yellow paddy soil. The results indicated that the application of organic materials significantly increased the contents of the soil organic matter and the yield of rice. The application of broad bean stalk, peat, pig manure compost, and biochar remarkably increased the soil pH, while the application of rape straw exerted no significant influence. The addition of organic matter reduced the available Cd content by 34.77%-82.69%. However, the effects of organic materials on the availability of As varied with the organic materials. this website The soil-available As content was significantly increased by the application of pig manure compost and biochar, while it was significantr content, and As and Cd contents in the Fe plaques.In order to explore the effects of the exogenous addition of plant hormones on the antioxidant system and Cd absorption and accumulation of rice seedlings under Cd stress, the transportation and accumulation of Cd was reduced in plants to alleviate the stress of Cd on the rice. With the rice seedlings of Zhongjiazao 17 as the research object, a hydroponic experiment was carried out with three Cd concentration treatments (0, 5, and 25 μmol·L-1), and four exogenous plant hormone treatmentsno plant hormones, 100 μmol·L-1 melatonin (MT), 0.2 μmol·L-1 2,4-epibrassinolide (EBL), and 0.2 μmol·L-1 jasmonic acid (JA), for a total of 12 treatments, each treatment repeated three times. The contents of Cd in the rice seedlings were analyzed, as well as the content of MDA, POD, CAT, and reduced GSH in the shoots and roots of the rice seedlings. The results indicated that under the stress of 5 μmol·L-1 and 25 μmol·L-1 Cd, the addition of MT, EBL, and JA significantly reduced the MDA content of the shoots by 11%-24%, and the roots and shoots were healthy.
