This paper presents the identification of galaxy clusters from the photometric redshift catalog based on three imaging surveys of SCUSS, Sloan Digital Sky Survey, and unWISE. By applying a fast clustering algorithm, we obtain a total of 19,610 clusters in the redshift range of 0.05 < z < 0.65 over a sky area of about 3700 deg² in the south Galactic gap. Monte Carlo simulations show that the false detection rate is about 8.9%. The redshift uncertainty is estimated to be about 0.013. The mass and richness of detected clusters are derived through the calibration based on the measurements of X-ray emission and Sunyaev-Zel'dovich effect. The median mass is 1.2 x 10¹⁴ M_☉.
