The pulsar PSR B0950+08 is one of the brightest pulsars with extremely high flux intensity. To understand the pulse profile properties, we conducted a study using one hour of data from FAST observations, focusing on the shape of the average pulse profiles, polarization characteristics, and microstructure. We find that both the width of the average pulse profile and the fraction of linear polarization change with varying relative flux intensity. Moreover, we report, for the first time, a strong linear relationship between the profile width and the fraction of linear polarization for this pulsar. For average pulse profiles with different flux intensities, we observe jumps in the polarization position angle and changes in the profile shape. Distinct depolarization occurs at the polarization position angle jump, which is related to the pulsar's flux intensity. By performing an autocorrelation analysis on the single pulses, we obtained the characteristic width and period of the microstructure.
