The invention relates to the technical field of environment monitoring, in particular to an underground water monitoring and early warning method and
system based on multi-
source data fusion, and the method comprises the following steps: obtaining
water quality, flow velocity, temperature and pH value data, adjusting the collection frequency, verifying the state of a sensor, forming a
water quality and geologic
feature data set, analyzing rainfall,
air temperature, permeability and
water flow dynamic state, and obtaining a
water quality and geologic
feature data set. And generating a seepage trend, identifying a
pollutant diffusion path, range and main path, evaluating a
diffusion rate and influence, and generating a
pollution diffusion early warning level in combination with permeability and risk standards. According to the invention, through fusion analysis of multi-
source data, determination of the correlation between an underground water flowing mode and water quality change, timely capturing of the influence of meteorological change on underground water, accurate evaluation of
pollutant diffusion path, rate and influence range, improvement of timeliness and accuracy of
pollution early warning, and improvement of monitoring response speed through
automatic data processing. And timely and accurate decision support is provided for
groundwater resource management and
pollution control.
