Spatial and kinematical stratification in the gaseous envelopes of PMS objects containing zones of stellar wind and matter infall

Analysis of the rapid profile variations in the H alpha, \hei and \dn lines is presented for a number of PMS objects. The gaseous envelopes of these objects are shown to contain jet-like inhomogeneities, the regions of fast and slow wind, dense disc-like remote shells, and zones of matter infall onto the star.
