This invention belongs to the field of shrimp farming technology and discloses an AIoT-driven ecological coupling method for whole-field flat-culture of fruit and shrimp. The method divides the fruit and flower crop planting area into multiple flat-culture units and establishes unit relationships. Under basic flat-culture management conditions, crop impact data, shallow water environment data, bottom load data, and shrimp activity data are collected to establish historical baseline states for each flat-culture unit. During the flat-culture process, current data is collected to form plant impact state, shallow water environment state, bottom load state, and shrimp response state, and a current ecological state chain is constructed. Based on the comparison results between the current ecological state chain and the historical baseline state, abnormal relationships are identified, and target flat-culture units, associated flat-culture units, and dominant abnormal links are determined. A local zonal control scheme is generated and executed. After control, a retested ecological state chain is formed, and recovery conditions are determined, dominant abnormal links are corrected, or the control level is increased accordingly.
