Abstract: Quality measurement of river sediment particle size analysis method needs unified indicators and computation method. It is required that the relevant standard system is established for standard sample used to measure the quality of analysis method and supervise the working quality of routine analysis. For this reason，the unified quality measure ment indicators of river sediment grain size analysis method and the con sideration of establishing standard sample system were suggested，and the quality of grain size analysis method，the quality measurement indi cators of analysis method，the preparation of standard sample and the es tablishment of standard sample system etc were discussed in detail. Uni fied quality measurement indicators of river sediment grain size analysis method and the consideration of establishing standard sample system pro posed in here is scientific，reasonable and adaptable and operable.
