摘　　要：利用国控观测点位的空气质量监测数据,揭示了周口市主城区2019年近地面臭氧(O_(3))浓度的时间变化特征以及与前体物的相关性;并采用遥感解译与实地调查相结合的方法,分析了人类活动类型对周口市主城区近地面O_(3)浓度的影响。结果表明,O_(3)浓度具有明显的日、月、季节变化规律,在前体物中与二氧化氮浓度存在负相关性。人类活动与近地面O_(3)浓度相关性分析结果表明,O_(3)浓度与人类活动中工矿用地面积比例呈很强的正线性相关性,与农业用地面积比例呈较强的负线性相关性。人类活动对O_(3)浓度影响评价结果表明,影响程度明显的区域主要集中在川汇区中部以及淮阳县县城西南部的工业活动较密集区,这些区域的人类活动类型和数量均较多,开发建设活动明显,影响强度较大。Based on the air quality monitoring data collected from the national stations in Zhoukou City, we revealed the surface ozone(O_(3))concentration temporal variation characteristics in Zhoukou City in 2019 and their correlations with the precursors. Then, we used the remote sensing interpretation and field investigation method to analyze the influence of human activities on the surface O_(3)concentration. The results show that O_(3)concentration has obvious diurnal, monthly and seasonal variation, and there is a negative correlation between O_(3)concentration and nitrogen dioxide concentration in precursors. The correlation analysis results of human activities and surface O_(3)concentration show that O_(3)concentration has a strong positive correlation with the proportion of industrial and mining land area in human activities, and has a strong negative linear correlation with the proportion of agricultural land area. The influence assessment results of human activities on the surface O_(3)concentration show that the areas with obvious impact degree are mainly concentrated in the central part of Chuanhui District, and the industrial activities are concentrated in the southwest of Huaiyang County. There are many human activities of different types in these areas. The development and construction activities are obvious and their impact intensity is strong.
