As an important symbol and carrier of regional social economic activities, population mobility is a vital force to promote the re-agglomeration diffusion factors. An accurate timely grasp on impact COVID-19 epidemic between cities great significance for promoting prevention control development. This study proposes theoretical framework resilience assessment, using centrality nodality, hierarchy...

Abstract. Using a new high-resolution air quality reanalysis dataset for China five winters from December 2013 to February 2018, we examine the influence of large-scale circulation on daily PM2.5 variability through its direct effect key regional meteorological variables over three major populated regions China: Beijing–Tianjin–Hebei (BTH), Yangtze River Delta (YRD) and Pearl (PRD). In BTH, sha...

Biomass burning (BB) plays an important role in the formation of heavy pollution events during harvest seasons Beijing–Tianjin–Hebei (BTH) region by releasing trace gases and particulate matter into atmosphere. A better understanding spatial-temporal variations BB BTH is required to assess its impacts on air quality, especially haze pollution. The fourth version Global Fire Emissions Database (...

Abstract North China faces severe groundwater overdraft because of unsustainable use. However, consumers local have rarely been precisely delineated. As such, identifying external groundwater‐intensive products may promote targeted policies from the consumption side, especially for most water‐scarce Beijing‐Tianjin‐Hebei (BTH) metropolitan area, which has important links to food security and ac...

Coal-to-gas/electricity conversion (hereafter referred to as CTGC/CTEC) the core project of a clean heating campaign has been widely adopted replace and reduce combustion residential coal in Northern China since 2017. In this study, simulations based on WRF-Chem model were carried out quantitatively assess impacts CTGC/CTEC air quality Beijing–Tianjin–Hebei (BTH) region. It was found that proje...

Farmland fragmentation has emerged as the primary manifestation of global land use changes during last century. Following economic reform and opening up in China from 1980s, Beijing–Tianjin–Hebei (BTH) region witnessed continuous farmland fragmentation. Understanding spatial–temporal dynamics is crucial for formulating sustainable management strategies. However, specific causes locations remain...

Fine particulate matter (PM2.5) has a serious impact on human health. Forecasting PM2.5 levels and analyzing the pollution sources of are great significance. In this study, Lagrangian particle dispersion (LPD) model was developed by combining FLEXPART Bayesian inventory optimization method. The LPD capacity for real-time forecasting determination PM2.5, which refers to contribution ratio spatia...

Abstract. Multiple linear regression (MLR) models are used to assess the contributions of meteorology/climate and anthropogenic emission control trends PM2.5 concentration during period 2013–2018 in three regions eastern China, namely Beijing–Tianjin–Hebei (BTH), Yangtze River Delta (YRD), Pearl (PRD). We find that quantitative trend derived based on MLR results alone not credible because a goo...

Acibenzolar-S-methyl (BTH), bitkilerde zararlı böceklere karşı dayanıklılık veya savunmanın tetiklenmesinde ticari olarak kullanılan, yeni nesil etkili maddelerin ilk temsilcilerinden birisidir. BTH’ın böceklerin kontrolünde kullanımı hakkında yapılan çalışmalar sınırlı görünmektedir. Bu çalışmada, Dekalp mısır (Zea mays Linnaeus (Poales: Poaceae)) çeşidi, çevre dostu-bitkisel BTH içerikli bir ...
