无人机大气环境监测虽然处于起步阶段,但已成为环保部门一项重要的工作内容,对于提高突发性大气污染事件的预防及应急监测具有重要意义。本文以化工污染气体排放高危区齐鲁化学工业区为研究区,利用搭载有高分辨率相机和污染气体监测仪的旋翼无人机(“环鹰一号”)系统,结合地面核查验证的方式,设计了一氧化氮(NO)、一氧化碳(CO)和二氧化硫(SO2)3种污染气体污染遥感监测流程及方法。通过实验区地面验证,以及150、200、250、350 m高度污染气体浓度监测结果分析表明,化工园区污染气体排放具有空间水平差异及垂直扩散特征,联合水平和垂直异常值分析,能为提前排查污染源排放提供有效支撑。本研究是无人机在环保部门大气环境监测中的实际应用,能为后续化工园区及重点企业污染物排放定期监管提供技术支持。

Although atmospheric environment monitoring based UAV is a cutting-edge technology, it has become an important method for environmental protection departments. It is significant for protecting and emergency monitoring of sudden atmospheric pollution incidents. Qilu chemical industrial zone with high-risk region of contaminative chemical gas emission is took as the study area. In this paper, we combined the rotor UAV system (HY-1) that equipped with high resolution CCD and the pollution gas monitor with in-situ measurements for three pollution gases of NO, CO and SO2. The results of the three pollution gas concentration distributions at the heights of 150 m/200 m, 250 m, 350 m and the ground level showed that the pollution gases in the chemical industrial zone present a horizontal difference and vertical diffusion characteristics. Analyzing the horizontally and vertically abnormal values of pollution gas concentrations from UAV can be efficient in supporting pollution pre-investigation. This research is a practical application of UAV in atmospheric environment monitoring by environmental protection departments, which can provide a technical support for regular supervision of pollution gas emission in chemical industrial zones and related enterprises.
