摘　　要：由于水体重金属污染条件多变,导致污染范围监测难度较大,为提高水体重金属污染范围监测效果,设计一个基于遥感技术的水体重金属污染范围监测方法。采用遥感技术获取监测目标影像,通过对图像进行多尺度分割,利用暗像元素,将其引入适当的大气修正模型,得到各个参数,以获取真实的地面反射率,在不同的光谱上建立计算关系,以突出目标地物,剔除非目标地物,实现水体重金属污染范围监测。实验结果表明,所提出的基于遥感技术的水体重金属污染范围监测方法能够准确对污染浓度划分,并确定水体化工的污染范围。Due to the uncertainties of water chemical pollution,it is difficult to monitor the pollution range.In order to improve the monitoring effect of water chemical pollution range,a monitoring method of water chemical pollution range is designed based on remote sensing technology.Remote sensing technology is used to obtain the image of the monitoring target.Through multi-scale segmentation of the image,dark image elements are used to introduce it into an appropriate atmospheric correction model,and various parameters are obtained to obtain the real ground reflectivity.The calculation relationship is established on different spectra,so as to highlight the target features and eliminate non-target features,and realize the monitoring of the chemical pollution range of water bodies.The experimental results show that the proposed monitoring method based on remote sensing technology can accurately divide the pollution concentration and determine the pollution range of water chemical industry.
