This invention relates to the field of groundwater environmental assessment, specifically to an intelligent assessment method and system for groundwater environmental effects based on multi-field coupling. The method takes any spatial unit of the area to be assessed and its corresponding time period as the target spatiotemporal unit, and forms target field pairs from any two fields. Correlation analysis is performed on key indicator data of the target spatiotemporal unit with respect to the target field pairs to obtain the interaction strength coefficient of the target spatiotemporal unit with respect to the target field pairs. The spatial distribution and temporal variation trend of the interaction strength coefficient are analyzed to obtain the spatiotemporal coupling factor of the target field pairs. Combined with key indicator data of the spatiotemporal unit with respect to different fields, a visual assessment of the groundwater environmental effects in the area to be assessed is performed. This invention quantifies and integrates the complex nonlinear and spatiotemporally variable interactions between seepage fields, chemical fields, and temperature fields in the groundwater system, improving the assessment effect of groundwater environmental effects.
