The invention discloses a GPS interference area identification and troubleshooting method and device based on ADS-B data, and the method and device can quickly reflect the GPS interference condition and troubleshoot a GPS interference area. The method comprises the following steps: (1) calculating a GPS interference investigation indication index of an investigation area in an airspace: based on actual data, an ADS-B positioning principle and a GPS working principle, analyzing laboratory GPS suppression interference simulation experiment data and actual interference event data at the same time to obtain a universality rule and conclusion, and according to a data correlation result, calculating the GPS interference investigation indication index of the investigation area in the airspace; establishing a quantifiable comprehensive indication index; and (2) an intra-area GPS interference identification and determination method: calculating the indication index of each track, dividing the calculated indication ind
