The invention relates to a safety disposal digital twinning method and system based on an intelligent scoring mechanism. The system comprises an emergency disposal equipment module, a disposal verification module and an algorithm intelligent scoring module, wherein the method comprises the following steps: firstly, establishing a virtual-real mapping relation between the emergency disposal equipment module and a digital twinning model; then, carrying out atomization arrangement design on the disposal script in a processing and verifying module of the digital twinning model, constructing a plugging, performing unplugging, performing verifying and evidence obtaining process, extracting disposal effect data, uploading the disposal effect data to the algorithm intelligent scoring module in the digital twinning model, and sequencing disposal schemes of the security events through a disposal effect scoring algorithm; and finally, issuing the sorted disposal schemes to a disposal process, preferentially selecting an optimal disposal scheme, and issuing an instruction to corresponding equipment through a data transmission channel to dispose a security event. According to the invention, dynamic linkage processing of safety events can be realized.
