摘　　要：介绍了NSRL二期工程中束流测量系统的改造,包括DCCT测量系统、闭轨测量系统、基于束流准直系统、工作点测量系统、光位置测量系统和200 MeV直线加速器能谱测量系统.这些测量系统为合肥光源的运行调试和机器研究提供了有效的手段.另外,还给出了这些系统的应用和测量结果.The upgrade of beam diagnostics in NSRL Phase Ⅱ Project was described. These new beam instruments include a DCCT measurement system to measure the beam DC current and beam lifetime, a closed orbit measurement system to measure the beam position, a beam-based alignment system using a switchable shunt resistor to measure the offset of the beam position monitor （BPM） with respect to the magnetic center of a quadrupole, a tune measurement system to measure the beam tune and chromaticity, a photon beam position measurement system to measure the SR position, and a 200 MeV energy spectrum analytic system to measure the beam energy spectrum. Some applications of these measurement systems and their measurement results were presented.
