The invention relates to a mountainous area railway low-altitude survey operation method. The method overcomes the problem that the existing operation method cannot meet the operation requirement of aspecial working environment of a complex mountainous area, can ensure the safe survey operation of an unmanned aerial vehicle in the complex working environment of the mountainous area, and can improve the mountainous area low-altitude non-contact survey precision. The method comprises the following steps of S1, analyzing an operation environment to be subjected to low-altitude survey, and formulating a low-altitude survey operation and geological interpretation technical scheme; S2, carrying out the large-scale and rapid remote sensing interpretation on a survey area to obtain the macroscopic engineering geological information, and obtaining the large-scale DEM and images of the survey area; S3, enabling a low-altitude flight reconnaissance platform to adopt an unmanned aerial vehicle and a helicopter to separately determine and carry the corresponding reconnaissance devices according to the surface features; and S4, carrying out multi-means combined interpretation analysis, adoptinga GIS platform, establishing a three-dimensional geological interpretation sand table, realizing the fusion integration of the remote sensing satellite data and the helicopter and unmanned aerial vehicle survey data, so that the combined interpretation analysis of survey objects is realized.
