The invention discloses a method for on-site treatment and resource utilization of architectural ornament rubbish. The method comprises the following steps that front end pre-treatment module treatment is conducted, specifically, a torn-down and built site is subjected to leveling and planning firstly, then the architectural ornament rubbish which is distributed in a scattered mode is transshipped to a centralized stacking area of materials at a short distance through a professional vehicle, and part of the light materials which are sorted is subjected to classified stacking through a pre-treatment facility; middle end movable crushing treatment module treatment is conducted, specifically, raw materials which are sorted through manual work are sent to a combined movable crusher to be subjected to processing treatment through an excavator or a loader, and produced aggregates with different specifications are stacked to a finished material stacking area; and rear end resource utilization module treatment is conducted, specifically, the light materials sorted by the front end and the aggregates crushed by the middle end are directly used or treated or subjected to regeneration treatment on site, so that the requirement of resource utilization is met. According to the method for on-site treatment and resource utilization of the architectural ornament rubbish, reasonable and effective resource utilization of the architectural ornament rubbish can be achieved, and the environmental pollution problem caused by random storing of the architectural ornament rubbish is avoided.
