The invention relates to the technical field of limestone mine ecological regreening, in particular to a method for selecting a limestone mine ecological regreening technology based on a three-dimensional point cloud model, and comprehensively utilizes an unmanned aerial vehicle oblique photography technology and a three-dimensional geographic information software platform. Two-dimensional plane design can be converted into a three-dimensional stereoscopic model, a DSM model, a DOM model and a TIN model to be fused with a current situation real scene three-dimensional model, through comprehensive analysis of limestone mine three-dimensional point cloud data, treatment of the limestone mine ecological damage problem and the slope stability problem is compared and matched with rich ecological regreening technical means, and the comprehensive analysis of the limestone mine three-dimensional point cloud data is achieved. The limestone mine area is treated and restored in a partitioned mode according to the charac
