Abstract： Song-Liao River Basin is a significant commodity grain base and industrial base in China， as
well as a concentrated distribution area of wetlands. With the development of social economy and the inten⁃
sified impact of climate change，the problems of water resources and water environment in Song-Liao River
Basin have become prominent，which have threatened food security，ecological health and economic growth.
Focusing on the major national needs of "guaranteeing national food security， promoting the construction of
ecological civilization， and revitalizing the old industrial base in Northeast China"， this paper analyzes the
four major problems faced by the Song-Liao River Basin， including large-scale agricultural irrigation， wet⁃
land restoration and protection，river-estuary pollution control，and urban multi-source water supply and re⁃
viewed research progress of water resources comprehensive regulation in Song-Liao River Basin. Following
the new water governance concept of "water saving priority， spatial balance， systematic governance， and
two-handed effort"， solutions of the four major problems are explored from three aspects： basic research，
regulation technology，and safeguard measures. The aim is to give full play to the comprehensive regulation
and control of water resources under the conditions of connecting rivers， lakes and reservoirs in the
Song-Liao River Basin， which plays important roles in improving the ability to guarantee the safety of ur⁃
ban and agricultural water supply， promoting the restoration and improvement of the wetland ecosystem，
and prevent river-estuary pollution，so as to meet the sustainable development of economic society and eco⁃
logical environment，and achieve the harmonious coexistence of man and nature.
Keywords： water resources； comprehensive regulation； water supply security； wetland ecological restora⁃
tion；pollution control；Song-Liao River Basin
