Abstract：
In order to study the ecological and atmospheric recovery of the Hexi Corridor region, this paper analyzes the migration changes of land use characteristics and utilizes multivariate data and BenMAP-CE software to study the pollution characteristics of ozone and its precursors and the impact on human health in the Hexi Corridor region. The results showed that the increase of cultivated land area in the Hexi Corridor mainly originated from grassland. The MDA8-O3 concentrations met the primary and secondary standards of the Ambient Air Quality Standards on 43% and 99% of the days, respectively. NO2 showed a negative weekend effect with O3, and HCHO was opposite to it. Temperature, barometric pressure, and vegetation were highly correlated with O3-NO2-HCHO. Ozone pollution in the study area caused about 60% of all-cause premature deaths due to cardiovascular diseases. The study suggests that controlling exogenous transport in Wuwei City during the high ozone period (except August) is mainly dominated by the west and northwest, and that synergistic management of VOCs and NOx emissions can reduce O3 pollution and, consequently, reduce the risk to human health.
摘要：
为了研究河西走廊地区的生态和大气恢复，本文分析了河西走廊地区土地利用特征的迁移变化，并利用多元数据和BenMAP-CE软件研究了河西走廊地区臭氧及其前体物的污染特征及其对人体健康的影响。结果表明，河西走廊耕地面积的增加主要来自草地。MDA8-O3浓度在43％和99％的天内达到环境空气质量标准的主要和次要标准，分别。NO2对O3表现出负的周末效应，而HCHO则相反。温度,大气压力,植被与O3-NO2-HCHO高度相关。研究区域的臭氧污染导致约60％的所有原因因心血管疾病而过早死亡。研究表明,在高臭氧期(8月除外),控制武威市外源运移主要以西部和西北部为主,VOCs和NOx排放的协同管理可以减少O3污染，因此,降低对人类健康的风险。
