“松辽运河”是东北地区计划中的一项跨流域调水工程。东北地区的人均径流量占全国平均数的64％,属全国的少水地区之一。然而,松花江流域由于缺乏大型控制性工程,每年约有4×1O~(10)m~3多的水量(接近辽河流域多年平均径流量的3倍)白白流入大海而未被利用。辽中南是东北工业最发达的地区,近年来经济发展很快,城市人口相对集中,而地表径流缺乏。水资源紧张已 The “Songliao Canal” is an inter-basin water transfer project planned by the Northeast China. Northeast China’s per capita runoff accounts for 64% of the national average, which is one of the less-water-intensive areas in the country. However, due to the lack of large-scale controlled projects in the Songhua River basin, about 4 × 10 ~ 10 m 3 of water volume (nearly three times of the average annual runoff in the Liaohe River Basin) flows into the sea without being utilized. Liao Zhongnan is the most developed northeast industry in recent years, rapid economic development, the urban population is relatively concentrated, while the lack of surface runoff. Water stress has been
