The invention relates to the technical field of geological environment monitoring, and discloses a contaminated site water and soil environment multi-factor one-stop management system, which comprisesthe following steps: S1, collecting data; s2, performing remote sensing interpretation; s3, performing field investigation and field test; s4, establishing a model; and S5, performing visual system integration. In S1 data collection, hydrogeological structures, underground water flow field characteristics, land utilization and surface water system distribution, pollutant discharge disposal and water and soil test data directly related to the water and soil environment of a polluted site are adopted. According to the invention, pollution indexes, distribution rules and pollution sources in surface water, underground water and soil are found out, and underground water quality pollution evaluation, antifouling property evaluation and pollution prevention and control division are completed. The invention analyzes historical pollution source distribution by utilizing remote sensing, and analyzes a water and soil pollution generation and development process; the geophysical prospecting technology is innovatively applied to describe soil and underground water pollution, and investigation efficiency is improved; and aquifer management and reasonable development are facilitated.
