A method of leak detection for oil and gas pipeline based on excitation response and system thereof includes: applying an active excitation signal (a pressure pulse directly input by human) or a passive excitation signal (a pressure fluctuation caused by opening and closing valves, etc.) to an oil and gas pipeline with existing leakage points, the excitation signal is reflected at the pipeline boundary and the leakage, and the reflected pressure wave continues to propagate to upstream and downstream, and finally is collected by the dynamic pressure transducer, then the existing leakage of the pipeline is detected and positioned by analyzing the transient response signal and the reflected pressure wave of leakage signal.
