The invention relates to the technical field of surface water environment quality pollution control and management, in particular to a historical remaining mining area surface water environment treatment limit and threshold determination method which comprises the following steps: S1, acquiring historical remaining mining area surface water environment data; s2, building a surface water environment mathematical model; s3, formulating a typical scene scheme and simulating a water quality standard reaching distance; s4, setting a pollutant river standard section based on the typical scene scheme; s5, calculating the pollution load of the river pollution control section based on the surface water environment mathematical model; and S6, setting a river pollution control section threshold. The method for determining the surface water environment treatment limit and threshold of the historical remaining mining area is constructed, the river buffer area is arranged, and the pollutant discharge standard and the surfa
