Abstract：
With a Bhabha events generator the Bhabha scattering effective integral cross section for Beijing Spectrometer(BES)luminosity monitor is calculated based on the parameters of the monitor and Beijing Electron-Positron Collider(BEPC)beams.This cross section value can be used for calculating the luminosity of BEPC beams with the systematic error less than 3%.The measured data are in good agreement with the calculation.
