En vigorously implemented in Xi’an, but handful of research have assessed the effectiveness of environmental management in improving atmospheric pollution. The atmospheric pollution in Xi’an exhibits seasonal dependence. Bare surface and powerful wind in spring, and biomass burning and coal combustion from intensive heating demand in winter accompanied with meteorological aspects closely related to atmospheric pollutionall market an abundance of particulate matter and visibility impairment [1,six,22]. Evaluation and improvement of air high-quality within the context of changes in energy consumption and fast urbanization is conducive to the future development and sustainability of other megacities in northwest China. Within this study, PM10 and PM2.5 from 13 air monitoring stations in Xi’an from 2013 to 2017 were analyzed. We aimed to: (1) characterize the temporal and spatial variations of PM10 and PM2.5 in Xi’an; (two) analyze the relationships involving particulate matter and meteorological circumstances; and (three) discover the response in the concentration and emission intensity of atmospheric pollutants for the environmental management. This study aims to provide a scientific framework for atmospheric pollution management. two. Materials and Approaches 2.1. Study Region Xi’an, the capital of Shaanxi Province, is really a megacity in western China, situated at the central portion in the Guanzhong Plain, with all the Loess Plateau for the north, along with the Qingling Mountains for the south. Xi’an is situated in a subhumid and warm temperate region below the influence on the East Asian monsoon with hot and humid summers, and cold winters. Through the warm Cymoxanil Fungal period (Might ctober), winds blow in from southern China; during the cold period (November pril), winds in the desert regions of northwestern and western China are dominant. More than the period of 2001017, the average annual temperature was 13.six C, plus the annual precipitation was 558.2 mm (http://data.cma.cn/, accseed on 1 March 2020).Atmosphere 2021, 12,western China are dominant.
