An analysis of the photo-polarimetric activity of Ae/Be Herbig stars and the types of Hα profiles observed in their spectra was carried out using data from the literature. This analysis supports the presence of a relationship between the type of Hα, profile and the level of photo-polarimetric activity in young stars. Single profiles and P Cygni profiles are observed predominantly in stars with low activity; two-component profiles (characteristic of an accretion disk) are observed more often in stars with a high level of photometric activity. The existence of a relation of this sort indicates that the various shapes of the observed Hα profiles may be explained in the framework of a single axially symmetric model with circumstellar gaseous envelopes observed at different angles to the line of sight. A phenomenological model of such envelopes is discussed.
