Abstract: Objective To evaluate the value of simulation experiments in identifying causality for agricultural environmental damage, especially when the site conditions are compromised or pollutants are present at non-detectable levels. Methods Field and laboratory simulations were conducted, in which key variables such as pesticide concentrations were rigorously controlled, along with the setup of replicates and controls, to reconstruct the damage process. Case studies involving yam, adzuki bean, and crucian carp were analyzed. Results The simulation experiments successfully reproduced damage symptoms in crops and aquatic organisms, establishing dose- response relationships and causality between pollutants and observed damage. This approach provided critical scientific evidence in cases where the original scene was destroyed or pollutants could no longer be detected. Conclusion Simulation experiments serves as an effective auxiliary tool in the judicial identification of agricultural environmental damage. However, limitations such as model simplification and subjective parameter selection must be acknowledged. It is recommended to enhance their reliability through standardized procedures and multidisciplinary validation.
