Abstract China faces severe air pollution issues due to the rapid growth of economy, causing concerns for human physical and mental health as well behavioral changes. Such adverse impacts can be mediated by individual avoidance behaviors such traveling from polluted cities cleaner ones. This study utilizes smartphone-based location data instrumental variable regression try find out how quality affects population mobility. Our results confirm that does affect outflows cities. An increase 100...
Fine particulate matter (aerodynamic diameters of less than 2.5 µm, PM2.5) air pollution has become one the major environmental challenges, causing severe issues in urban visibility, climate, and public health. In this study, ground-level PM2.5 concentrations, air-quality categories (AQCs), health risk (HRCs) over Beijing, China, have been estimated based on mid-visible column aerosol optical depth (AOD) measurements extracted from Moderate Resolution Imaging Spectroradiometer (MODIS) data...
Abstract Particulate pollution has become more than an environmental problem in rapidly developing economies. Large-scale, long-term and high concentration of particulate occurs much frequently, which not only affects human health but also economic production. As PM 10 is one the main pollutants, prediction its great significance. In this study, we present a forecast model based on long short-term memory (LSTM) neural network method evaluate performance predicting daily concentrations at...
Abstract While the ongoing Russia–Ukraine war threatens global nutrition security, magnitude and extent of its impact remain underexamined. Here we show that, with lowest level duration, severity, sanction, countries involved, direct indirect impacts sanctions could newly place 67.3 million people (roughly equals total population France) in undernourishment 316.7 Bangladesh Russia) suffering from extreme national food insecurity. Approximately 95% affected are developing countries,...

The species and distribution of trees in a forest are critical to the understanding ecosystem processes development management strategies. Subtropical landscapes feature complex canopy structure high stand density. Studies on effects classification algorithms remote sensing-based identification tree few. GF-2 is first satellite China with sub-meter accuracy which has resolution short replay cycle. Here, we considered three representative types (Masson pine, Chinese fir, broadleaved evergreen...
Abstract The spatial and temporal variations of aerosols their relationships with meteorological conditions in Southwest China were studied to understand the aerosol‐meteorology interactions. distribution shows a strong “basin” effect highest values Aerosol Optical Thickness at 0.55 µm (AOT, also denoted τ ) (>0.70), fine‐mode AOT (τ 0.55‐fine (0.40 ~ 0.67), coarse‐mode 0.55‐coarse 0.54), all observed Sichuan Basin. variation seasonal mean dissimilar cyclic variations, which is due...
To evaluate the effectiveness of control strategies during G20 Summit (August 24–September 6, 2016), five sites were selected for investigating variation in air pollution city Hangzhou and its surrounding areas. The results showed that quality greatly improved after implementation strict emission controls. Compared to same dates from preceding years, period exhibited low relative humidity early stage 27–31) no significant differences other meteorological conditions. SO2, NO2, PM10, PM2.5...
Ferredoxins (Fds), a category of small iron-sulphur [2Fe-2S] cluster-containing proteins, localize in plastids and are required for distributing electrons from photosystem I (PSI) to downstream metabolic reactions (Hanke Mulo, 2013). Based on their expression pattern redox potential, Fds higher plants classified into leaf (photosynthetic) root (non-photosynthetic) types. In rice, five typical Fd genes have been identified, among which OsFd1 encodes the primary photosynthetic Fd. Knockout...
Atmospheric particulate matter pollution in Zigong City southern Sichuan is quite severe. The average concentrations of PM10 and PM2.5 from 2015 to 2018 were (95.42±9.53) μg·m-3 (65.95±6.98) μg·m-3, with an obvious trend decline. winter much higher than other seasons, the highest being(138.08±52.29) (108.50±18.05) January, respectively, whereas summer, lowest. ratio 69.12%, about 1.17 times that summer; thus, mainly responsible for air pollution. To explore potential sources fine (PM2.5)...
With the rapid development of e-commerce logistics, logistics in modern society is facing fierce competition. The expansion scale and overflow waste packaging also increase burden enterprises. Based on 512 sample data collected from Mianyang, Yibin other cities, this paper establishes regression equation by setting independent dependent variables, uses linear methods such as correlation coefficient, parameter estimation, SPSS analysis to analyze. Through investigation demand light...
In this paper landslide susceptibility mapping and model performance assessment was conducted using three models, logistic regression, GAM, SVM, in a study area Shenzhen, China. Ten factors, slope angle, aspect, elevation, plan profile curvature of the slope, lithology, NDVI, building density, distance to river, fault were selected as influencing factors for occurrences. All models trained resulting maps created. The performances then assessed by AUC values through 10-fold cross-validation....
Owing to the complex mesoscale meteorological dynamics, deep basin topography and pollutants emissions, Chengdu Plain (CDP) situated at west border of Sichuan Basin (SCB) have suffered excessive ozone (O 3 ) pollution in warm season. However, meteorology-driven mechanism associated dominant processes underlying elevated O levels are not well elucidated due limited ambient measurements. Here, we adopted trace gases data measured by basin-wide network combination with a high-resolution...
In recent years, China's air quality has been improving, and the concentration of atmospheric particulate matter decreased significantly. this study, pollution characteristics trends two typical representative cities (Beijing Chengdu) were analyzed. The geographical locations, emissions, meteorological diffusion conditions compared, to evaluate relative contribution reduction regulations in decreasing fine (PM2.5) concentrations. results showed that number heavily polluted days episodes...
