The invention relates to an artificial climate system, and particularly relates to an artificial climate system for a soil-vegetation-atmosphere continuous system model test, belonging to the field of environmental geotechnics. The artificial system can simulate the natural change of climate environments such as wind, rain, illumination, temperature, humidity and the like. The artificial climate system consists of an artificial climate box body, a box body liner, a light source, a rainmaking device, an intelligent control system, a multi-channel converter, an airflow circulation system, a rainwater circulation system, a temperature/humidity regulation system, a CO2 and O2 regulation system, a climate parameter sensor group and a digital imaging system. The system can realize automatic feedback regulation of the rainfall intensity, the illumination direction and intensity, the wind speed and direction and the temperature and humidity. Meanwhile, by adopting a top-rotatable rainfall illumination integrated device, the problem of position overlapping of the rainfall device and the illumination device is solved, and the uniformity of the illumination intensity and rainfall intensity in the horizontal plane is guaranteed.
