Abstract:Water and sediment regulation is an important tool for the sustainable development of the Yellow River
Basin system. This paper innovatively puts forward the water and sediment regulation system “139+”in the Yellow
River Basin to guide the multi-objective collaborative regulation with the management concept of comprehensive cov⁃
erage and deep coordination. The system takes multi-objective collaborative water and sediment regulation in the
Yellow River Basin as the overall goal,including 3 sub-objectives of flood and sediment transport safety and effi⁃
ciency,stable social and economic development,and benign maintenance of ecological environment. Besides,the 3
sub-objectives include “9+”specific objectives. For different regulation needs and water and sediment scenarios,the
indicators can be selected flexible in the objective functions,and then the weights and thresholds will be dynamically
adjusted accordingly. The expression forms of water and sediment regulation system “139+”in each water and sedi⁃
ment scenario are analyzed,according to the regulatory paths of “bottom line regulation - dimension reduction optimi⁃
zation”in extremely dry years,“low limit regulation - dimension reduction optimization”in dry years,“appropriate
regulation-multi-dimensional coordination”in normal years,and “flood storage and replenishment - quality and effi⁃
ciency improvement”in wet years and extremely wet years. The results of multi-objective coordinated water and sedi⁃
ment regulation in Sanmenxia and Xiaolangdi reservoirs show that the three subsystems of flood and sediment trans⁃
port,social economy,and ecological environment can achieve high-quality coordination in normal flow years,and
improving the ecological satisfaction rate and power generation efficiency will help to improve the coupling coordina⁃
tion level.
