The invention discloses a water quality tracking and monitoring method for a water environment, which comprises the following steps: S1, setting a plurality of image data acquisition points in a monitoring area of the water environment, and uniformly distributing the plurality of image data acquisition points in the monitoring area; S2, obtaining a relational data set (fb', A) of the multispectral reflectivity of the water area of the image data acquisition points and a water quality parameter A; s3, constructing a relation model of the multispectral reflectivity and the water quality parameters by means of the multiple relation data sets: ln(A)=m*ln(fb')+q, wherein m is a relation coefficient, and q is deviation; and S4, acquiring the multispectral reflectivity of the water surface above the monitored water area by using the unmanned aerial vehicle, and substituting the multispectral reflectivity into the relation model to obtain the water quality parameters of the water area. According to the method, a more accurate, higher-temporal-spatial-resolution and more complete rural water body pollution data set can be acquired and accumulated, and more useful information is provided for tracking and monitoring of rural water body pollution and prediction and analysis of the water environment pollution degree and the pollution range.
本发明公开了一种水环境水质跟踪监测方法,其包括以下步骤:S1:在水环境的监测区域内设置若干图像数据采集点,若干图像数据采集点均匀分布在监测区域内;S2:得到该图像数据采集点水域多光谱反射率与水质参数A的关系数据组(fb',A);S3:利用若干的关系数据组构建多光谱反射率与水质参数的关系模型:ln(A)=m×ln(fb')+q,其中,m为关系系数,q为偏差;S4:利用无人机在监测水域的上方获取水面的多光谱反射率,代入关系模型中,得到该水域的水质参数。本发明助于获取并累积更精确、更高时空分辨率、更完整的乡村水体污染数据集,为乡村水体污染的跟踪监测与水环境污染程度、污染范围的预测分析提供更有用的信息。
