“生态农业第一村”——颖上县小张庄与合肥市地面SO_2和O_3的观测分析

MEASUREMENTS AND ANALYSES OF SO_2 AND O_3 NEAR THE GROUND SURFACE IN "THE FIRST ECO-AGRICULTURE VILLAGE"—XIAOZHANGZHUANG AND HEFEI AREAS

本文介绍了1993年10月14—26日在牛态环境"全球五百佳"的小张庄和同年10月28日—11月6日在合肥市(中国科学技术大学东区校园)两地所进行的地面SO_2和O_3的观测结果,并给出了两地SO_2和O_3浓度平均概况及随时间变化的一些特征。结果表明,观测期间两地SO_2和O_3环境质量是好的,与SO_2浓度相比,两地NO_x的相对含量较高。分析还表明,风向对小张庄SO_2浓度无明显影响;雨和雾对两地SO_2和O_3有明显的清除作用。

The concentrations of SO_2 and O_3 near the ground surface were measured in 'Global 500'——Xiaozhangzhuang Eco-agriculture village and Hefei areas from 14 to 26 October and from 28 October to 6 November 1993, respectively. Some average characteristics and variation with time are presented in this paper. The results show that: the atmosphere over Xiaozhangzhuang and Hefei areas is clear for SO_2 and O_3 during the measurements; the concentration of NO_x is higher in both areas in comparison with that of SO_2; the influence of wind direction on the concentrations of SO_2 in Xiaozhangzhuang area is not apparent; the scavenging of SO_2 and O_3 by rain and fog is important in both areas.
