Based on SDSS and South Galactic Cap of u-band Sky Survey (SCUSS) early data,we use star counts method to estimate the Galactic structure parameters in anintermediate latitude with 10,180 main-sequence (MS) stars in absolutemagnitude interval of $4 \leq M_r \leq 13$. We divide the absolute magnitudeinto five intervals:$4 \leq M_r < 5$, $5 \leq M_r < 6$, $6 \leq M_r < 8$, $8\leq M_r < 10$, $10 \leq M_r \leq 13$, and estimate the Galactic structureparameters in each absolute magnitude interval to explore their possiblevariation with the absolute magnitude. Our study shows the parameters depend onabsolute magnitude. For the thin disk, the intrinsic faint MS stars have largelocal space density and they tend to stay close to the Galactic plane. Aplausible explanation is that faint MS stars with long lifetime experience longgravitational interaction time result in a short scaleheight. However, for thethick disk, the parameters show a complex trend with absolute magnitude, whichmay imply the complicated original of the thick disk. For the halo, theintrinsic faint MS stars have large local density and small axial ratio, whichindicate a flattened inner halo and a more spherical outer halo.
