Method and system for simulating spatial distribution of microplastics in rivers

Abstract

The application discloses a river micro-plastic spatial distribution simulation method and system. First, the small watershed range covered by each tributary is determined according to the geographic spatial data of the monitoring area, and the small watershed range of each tributary is divided into grids to obtain a corresponding grid division layer. Then, each grid in the grid division layer is valued according to the human activity data of the monitoring area to determine the human activity data of each grid. After that, the human activity data of all grids in the small watershed range of each tributary is statistically analyzed to determine the average value of the grid human activity data of the small watershed range of each tributary, and the micro-plastic abundance simulation value of each tributary is calculated through a micro-plastic distribution simulation model. Finally, according to the micro-plastic abundance simulation value of all tributaries in the monitoring area, the spatial interpolation algorithm is used to determine the micro-plastic spatial distribution result of the monitoring area. The wide-range and low-cost micro-plastic distribution rapid monitoring is realized.
