目前,遥感技术在城市环境监测中的应用有以下几个方面:城市绿地遥感,能快速准确摸清城市绿地现状及绿化水平,正确评价城市绿地及其生态效益;城市热岛遥感,较好地反映区域热岛效应和植被覆盖指数的关系;城市水体遥感,正确地反映出城市水环境质量的分布状况,能弥补常规监测的不足。
At present, the application of remote sensing technology in urban environmental monitoring has the following aspects: remote sensing of urban green space can quickly and accurately find out the status quo and greening level of urban green space and correctly evaluate urban green space and its ecological benefits; remote sensing of urban heat island can better reflect The relationship between regional heat island effect and vegetation coverage index; remote sensing of urban water body correctly reflects the distribution of urban water environment quality, which can make up for the lack of routine monitoring.
