Abstract：The Middle Route of the South-to-North Water Diversion Project has strategic importance for optimizing water allocation in China.Therefore it is crucial for ensuring safety of water quality in water source areas.Currently water quality of the water source areas is generally good,but more attention needs to be paid on risks such as failing to meet water quality standards,eutrophication,extreme algal bloom,and tailings pond leakage or dam failure.Based on review of current situation,it is found that water quality are mainly affected by factors of human activities,engineering,nature and management.Current situation and existing problems related to water quality safeguarding and management are summarized from the aspects of industrial development,pollution prevention and control,monitoring and supervision,risk prevention and water quality management.Based on the above,a comprehensive management framework is proposed,including a development system that couples and coordinates industries,agriculture,service,ecological industries and environment;a full process water pollution prevention and control system that reduces emissions at the source,controls process,and end treatment;a modern monitoring and control system that covers all elements,all weather,and all coverage;a full chain risk prevention and control system that identifies and evaluates,monitors and alerts,predicts and warns,and responds to emergencies;a comprehensive scientific and technical support system that boosts theoretical research,technical development,platform and talent development;and a comprehensive management system that led by legislation,perfect institutions and mechanisms,standardized construction and capacity building.This shall help to develop strategies and scientific solutions to ensure the sustainability of water diversion to the north.
