The invention discloses a hillside orchard crop growth analysis method and system based on unmanned aerial vehicle remote sensing, and the method comprises the steps: carrying an air remote sensing data collection device through an unmanned aerial vehicle, and collecting a target hillside orchard image; adopting a plant detection algorithm to obtain plant position information in the target hillside orchard image; planning an optimal traversal path by using an ant colony algorithm according to the plant position information; the unmanned aerial vehicle cruises according to the optimal traversal path and carries an aerial remote sensing data acquisition device to acquire a plant image at a preset height; according to the plant image, evaluating the growth state of the plant by using a chlorophyll-water stress index inversion model; through the method, the growth vigor of the plants in the hillside orchard can be analyzed, so that the growth condition of the hillside orchard crops can be mastered macroscopically
