The invention relates to an intelligent soot blowing system and method based on dynamic sensing of the soot state of a heating surface, and the system comprises soot blowers, inlet and outlet pressure measuring points are arranged at the upstream and downstream of the heating surface in front of and behind heat exchange tubes, the soot blowers are arranged at the upstream of the heating surface, and a plurality of rows of heat exchange tubes are arranged at the downstream of the soot blowers on the heating surface; the upper surfaces of the plurality of rows of heat exchange tubes closest to the upstream of the heating surface are provided with dust accumulation sensing temperature measuring points. The method has the beneficial effects that the heated surface pressure difference and the ash deposition sensing temperature measurement point are adopted as the basis for judging and calculating the ash deposition degree, the index of resistance increase of the heated surface caused by ash deposition and the heat
