    In this article we show that for every finite area hyperbolic surface X of type (g; n) and any harmonic Beltrami differential 􏰚 on X , then the magnitude of 􏰚 at any point of small injectivity radius is uniform bounded from above by the ratio of the Weil–Petersson norm of 􏰚 over the square root of the systole of X up to a uniform positive constant multiplication. We apply the uniform bound above to show that the Weil–Petersson Ricci curvature, restricted at any hyperbolic surface of short systole in the moduli space, is uniformly bounded from below by the negative reciprocal of the systole up to a uniform positive constant multiplication. As an application, we show that the average total Weil–Petersson scalar curvature over the moduli space is uniformly comparable to -g as the genus g goes to infinity.
