This application provides a method, apparatus, electronic device, and storage medium for detecting deforestation in forest areas, relating to the field of artificial intelligence technology, to solve the problems of poor real-time performance and high detection costs in forest deforestation detection. The forest deforestation detection method includes: upon detecting the presence of a first feature in a first forest area image, detecting the presence of a second feature in a second forest area image. The first forest area image is acquired by a detection device installed on an outdoor tower. The second forest area image includes all or some features of the first forest area image, and includes the first feature, which is a feature matching the features of deforestation equipment, and the second feature is a feature matching the features of tree felling. If the second forest area image contains the second feature, it is determined that deforestation has occurred in the forest area corresponding to the second forest area image.
