A model for predicting bioavailability of arsenic in site soil and a construction method and an application thereof, includes steps of: leveling soil after selecting a measuring point, vertically placing a measuring sleeve, fully supplying water to site soil to be measured, balancing for 20-40 min, measuring a water content in a soil volume not less than 40%, placing a piston DGT device into the measuring sleeve and pressing the device into soil, covering a top of the measuring sleeve with a wind shield, cleaning the piston DGT device after the measurement, analyzing a concentration of available arsenic by ICP-MS, and measuring available arsenic of soil; linearly fitting the available arsenic measured by a DGT method with human bioavailable arsenic measured by a UBM method, and obtaining a model for predicting bioavailability of arsenic in site soil.
