The invention provides a tectonic deformation neutral surface calibration method based on crustal stress longitudinal distribution characteristics, which comprises the following five steps: determining a tectonic deformation body, accurately calibrating a crustal stress size continuous well section, determining the current crustal stress size of a region, determining the position of a neutral surface and obtaining a plane distribution diagram of the tectonic deformation neutral surface. According to the method, the crustal stress longitudinal distribution characteristics of the wrinkled stratum are fully considered, the crustal stress magnitude accurate interpretation model is constructed according to multi-source data calibration logging, and a more reasonable and accurate neutral surface calibration technology is established through the obtained well section crustal stress magnitude continuous curve change; the curvature of the top surface of the structure and the distance between the neutral surface and th
