The utility model discloses an artificial simulation natural illumination plant population gas exchange detection box and detection system, the detection box device comprises a solar simulator, a surrounding seat and a sealing cover, the sealing cover is lightproof or is provided with a shading layer, and a light source lamp is arranged at the top of the inner side of the sealing cover; a ventilation mechanism is arranged on a side plate of the sealing cover; the detection system further comprises an air pump and a photosynthesis detector. According to the device, a closed space with good sealing performance can be conveniently formed around a plant, the carbon dioxide content of gas exhausted by the sealing cover can accurately reflect the group photosynthesis condition of the plant in the sealing time period of the sealing cover, and the plant group photosynthesis is detected; therefore, the photosynthetic carbon assimilation capability of crop populations on unit land area can be reflected more accurately;
