Abstract: With the transformation from traditional water conservancy to modern water conservancy, sustainable water conservancy and water conservancy of people′s livelihood, the hydropower survey design standard system has gradually perfected the standards of planning, survey and design fields, also united the construction organization design, mechanical-electronic and metal structure standards, and supplemented other fields such as land expropriation resettlement, environmental protection, soil and water conservation, safety assessment as well as energy conservation and emissions reduction. Aiming at future development tendency, we suggest that the design standard system should be improved further, so as to solve the existing phenomenon of crossing, replication and contradiction, add some new fields such as ecological environmental design, scenery design, informatization of water conservancy at appropriate time, so as to make the design standard system conform to development tendency.
