Since 2010, during the river and lake health assessment work across the country, which has been carried out by the Ministry of Water Resources, the river and lake health assessment technical sys-tem has been systematically researched and verified. The river and lake health assessment index system was constructed, including hydrological process and water resources, physical forms, water quality, aquatic organisms and social service functions, five levels of river and lake health grading standards were pro-posed, and a systematic river and lake health survey and evaluation method was formed. The standard and method were adopted in 36 rivers and lakes (reservoirs) in China. It has been proved that the river and lake health connotation and index system can systematically characterize the ecological features of rivers and lakes in China. The indicators are scientific and reasonable in overall, and the whole set of technical methods has good operability.
