The invention relates to an X80 hot rolled steel plate with good toughness, high strength and low tensile ratio and a production method thereof, and belongs to the technical field of low-carbon structural steel production. The plate blank comprises the following components: 0.02 to 0.08 percent of C, 0.01 to 0.35 percent of Si, 1.40 to 1.85 percent of Mn, less than or equal to 0.015 percent of P,less than or equal to 0.004 percent of S, 0.01 to 0.06 percent of Alt, less than or equal to 0.008 percent of N, less than or equal to 0.0002 percent of H, 0.008 to 0.02 percent of Ti, 0.03 to 0.11 percent of Nb, 0.01 to 0.35 percent of Mo, less than or equal to 0.90 percent of Ni, Cr and Cu complex additive, and the balance of Fe and inevitable impurity elements. The heating temperature of the plate blank is between 1,120 and 1,220 DEG C; a fist stage of controlled rolling is finished in an austenite recrystallization area, the single-pass pressing rate is 15 to 30 percent, and the final rolling temperature is between 960 and 1,080 DEG C; a second stage of controlled rolling is finished in an austenite non-recrystallization area, and the final rolling temperature is between 770 and 830 DEG C; and the rolled steel is cooled to between 450 and 580 DEG C at a speed of 10 to 30 DEG C per second. The steel plate has the advantages of high strength, good toughness and low tensile ratio.
