ABSTRACT
The connectivity of rivers and lakes is an important means in the comprehensive management of rivers, lakes and reservoirs. Facing the rapid development of related research and engineering practice in China, this paper discussed the concept, connotation and classification of river lake system connectivity, analyzed the evaluation methods and application scope of river lake system connectivity, summarized the related practice and evaluation system of river lake system connectivity engineering, and put forward the river lake system connectivity classification system, the coupling evaluation methods of horizontal, vertical and vertical connectivity of river and lake system, unified evaluation standards and methods of river and lake system connectivity engineering, and mechanism of river and lake system connectivity should be strengthened. More attentions should be paid to the negative effects of the river and lake system connection project. And the scientificity, rationality and sufficiency of the river lake water system connection project should be strengthened, so as to meet the current construction requirements of happy rivers and lakes.
