The coordinated development of Beijing, Tianjin, and Hebei is the core strategy of China’s political, economic, scientific, and cultural construction. The environmental protection of regional agricultural producing areas is a strategic location for the battle against pollution. The problem of excessive heavy metals Cd and Hg in the soil of agricultural producing areas is prominent in Beijing and Tianjin, and the pollution risk cannot be ignored. The main causes of soil pollution in the agricultural producing areas in the Beijing–Tianjin–Hebei region are heavy metal pollution by industrial development zones, sewage irrigation, inadequate sewage treatment capacity, imperfect regulations and policies, and backward technical standards. This study proposed to comprehensively deploy a “sky-ground integrated” environment monitoring system for the agricultural producing area, implement the clean production of in-dustrial and mining enterprises, and promote comprehensive strategies of soil pollution prevention and control such as comprehensive management of livestock and poultry pollution. Engineering cases for environmental pollution prevention and control of a pit-pond pollution site and an informal refuse landfill in Tianjin are enumerated to provide references for strategic decisions of soil pollution prevention and control in the Beijing–Tianjin–Hebei agricultural producing areas.
