Summary:The invention discloses a high-density city yellow muddy water phenomenon early warning method and system, and relates to the field of disaster early warning. The method comprises the following steps: acquiring a DEM image, a remote sensing image and a road map in an area range, and interpreting to obtain a water collection area classification data set, a vegetation coverage index data set, a land utilization classification data set, a current building road and bridge construction site plot pattern spot data set and a road grid data set; performing qualitative judgment and quantitative scoring on the data in each data set; carrying out weight comparison and calculation on the influence factors of each data set; performing weighted stacking on layers where different data sets are located to obtain a yellow muddy water susceptible area grade map; and acquiring ground feature identification point location data in the area range, extracting the landmark points and the road range in the danger level division range
