The dredging equipment standardization work of China began in the late 1970s，and further developed in the 1990s and early 2000s，especially in the last 5 years. Aiming at the development and evolution of dredging equipment standardization，we apply the method of classification comparison and standard content analysis to discuss the development and evolution of Chinas dredging equipment international，national，transportation，shipbuilding，water conservancy industry and group standards，point out and analyze the development characteristics and current problems of dredging equipment standards at each stage，and propose the suggestions for standardization of dredging equipment. It can provide the references for research and compilation of subsequent dredging equipment standards.
