Abstract：
The integrated luminosity for the two sets of BES data,collected at s=3.650,3.686GeV in 2002 and 2003,are carefully studied,and measured to be (6.42±0.24)pb^-1 and (19.72±0.86)pb^-1.The result provides basic input parameter in the measurements of cross sections at the above two energy points.
