The invention relates to the technical field of natural gas leakage detection, in particular to a natural gas leakage detection method and a multi-mode natural gas leakage detection system, and the method comprises the steps: obtaining at least two continuous frames of infrared video images of a to-be-detected region; converting the obtained two continuous frames of infrared video images to a preset size, and inputting the infrared video images into a trained natural gas detection model for detection to obtain corresponding detection results respectively; the natural gas detection model is constructed by taking a yolov5 model framework as a main body, a C2f network structure is used for replacing a C3 network structure, and SoftPool operation is used for replacing convolution operation used for 2-time down-sampling to carry out feature down-sampling; and based on the detection results corresponding to the two continuous frames of infrared video images, judging whether the result is a false result, otherwise,
