Shallow landslide monitoring and early warning method and device

The invention provides a shallow landslide monitoring and early warning method comprising the following steps that monitoring data corresponding to each monitoring index among a plurality of monitoring indexes is collected, wherein the plurality of monitoring indexes comprise rainfall, landslide surface displacement, soil body volume water content and pipeline strain of an oil and gas pipeline, and the oil and gas pipeline is laid in a shallow landslide; early warning grading data corresponding to each early warning grading index among multiple early warning grading indexes is determined basedon the monitoring data, wherein the multiple early warning grading indexes comprise an index used for representing deformation characteristics of the shallow landslide and an index used for representing failure characteristics of the oil and gas pipeline; a preset early warning grading model is acquired, wherein the early warning grading model is used for carrying out early warning grading on thelandslide risk of the sha
