摘要
传统的施工工地扬尘污染监测方法受到监测位点的限制,监测范围较小,造成获得的信息不完整,为此,设计基于遥感技术的施工工地扬尘污染自动监测方法。以粉尘颗粒物监测指标体系为依据,确定扬尘污染检测指标,根据施工工地中扬尘的主要来源,设置扬尘污染监测点位,通过卫星遥感技术计算扬尘颗粒表观反射率,以此反演出气溶胶分布,经过处理获得扬尘污染信息,实现施工工地扬尘污染自动监测。测试结果表明在监测位点相同的情况下,与传统的扬尘污染监测方法相比,基于遥感技术的监测方法监测途径不同,未受到监测位点的限制,监测的范围接近传统方法的2倍,适合应用在实际项目中。
The traditional monitoring method of dust pollution on construction sites is limited by monitoring sites and the monitoring scope is small,which results in incomplete information.Therefore,an automatic monitoring method of dust pollution on construction sites based on remote sensing technology is designed.Based on dust particles monitoring index system,dust pollution detection index is determined according to the main source of dust in the construction site.It sets up the dust pollution monitoring points,dust particle apparent reflectance,through the calculation of satellite remote sensing technology to the performance distribution of aerosols,processed for dust pollution information,to realize automatic construction site dust pollution monitoring.The test results show that,when the monitoring sites are the same,compared with the traditional monitoring methods of dust pollution,the monitoring methods based on remote sensing technology have different monitoring approaches,which are not limited by the monitoring sites,and the monitoring scope is close to twice that of the traditional methods,which is suitable for practical projects.
