The invention relates to a simulation testing system of a water circulation process under human activity disturbance conditions. The system comprises a simulation platform for simulating nature and human activities, which affect water circulation, and a monitoring platform for monitoring through a sensor, as well as a computer monitoring platform for controlling the simulation platform and performing data sampling and data processing on the monitoring platform, a seepage-proof pool, experimental soil, a rain shelter, a simulation rainfall device, a groundwater level simulation device, a water intake well, an observation device related to vorticity, an automatic weather station, a runoff detection device, a surface runoff sensor, a runoff instrument, a sensor for water content in the soil, a detection device and a control device. The simulation platform, the monitoring platform and the computer monitoring platform of the system disclosed by the invention are organically combined to form specific water circulation sub-systems among the various parts, namely the simulation device, the detection device and a control platform, and the integration of the sub-systems can realize the omnibearing simulation concept of a complex water circulation system of nature-manual work.
