مستخلص:	Agricultural products are a primary pathway for humans to accumulate heavy metals (HMs) via the soil-crop system and should therefore should be included as a crucial part of the food security in our country. Given that previous studies on protection zoning for preventing farmland HM pollution rarely considered agricultural products as a basic element, this study attempted to establish a zoning system for farmland HM prevention, which was based on the perspective of agricultural product pollution. We subsequently took a representative peri-urban area in the black soil region, which was provided with a higher risk of being polluted, as an empirical case. The results indicated that:① the comprehensive quality index of agricultural products (IICQ AP ) was 1.09, illustrating only a mild HM pollution, with Pb and Ni having the highest accumulation levels; ② the human health risk index ( Q HI ) was 0.61, showing no risk for human health; and ③ the designed zoning method revealed 89.45% of the farmlands to be risk-free at the moment and 10.55% of the farmlands to be under low risk of HM pollution in agricultural products. According to the zoning results, we suggested prioritized protection and an early-warning strategy, respectively, and further recommended prevention methods such as accumulation intervention, crop restructuring, and in-situ passivation. The results served to enrich the theoretical basis for preventing farmland HM pollution, to reinforce the management standards for agricultural products in the black soil region, and also to build a differentiated urban-rural farmland protection system.
