辽宁省是严重缺水省份之一,年人均占有水量为930 m~3,为全国人均数的1/3。辽宁中部经济发达地区缺水更加严重,据沈阳市调查,因缺水每年影响工业产值12亿元。水源不足也给城市人民生活带来很大影响,沈阳、鞍山、辽阳等市生活用水质量差,定时限量供水普遍存在。由于大量超采地下水,沈阳市已形成250 km~2的漏斗区,最大降深37m,辽阳市漏斗区面积达254 km~2,最大降深31m,缺水地区出现工农业争水和工业挤占农业用水现象。辽宁省每年缺水16亿m~3,到2000年将缺水50多亿 m~3,如不尽早解决,势必带来一系列社会问题。目前,全省水利工程每年为国民经济各部门供水总量达113亿 m~3,在1985、1986年汛期发挥的错峰调节作用,减少直接损失10亿多元。建国40年来,全省共发生大的旱涝灾害10多次,都造成粮食大幅度减产,所以,水利的兴衰对工农业生产及城乡建设起着很大的制约作用,这就决定了水利产业在国民经济建设中占有特殊的地位。
Liaoning Province is one of the major water-scarce provinces with an average annual water consumption of 930 m 3, which is 1/3 of the national average. The water shortage in the economically developed areas in central Liaoning is even worse. According to a survey conducted in Shenyang City, the annual industrial output value of 1.2 billion yuan is affected by water shortages. Inadequate water supply also has a great impact on the lives of urban residents. The quality of domestic water used in cities such as Shenyang, Anshan and Liaoyang is poor, and the water supply on a regular basis is ubiquitous. Shenyang City has formed a funnel zone of 250 km ~ 2 with a maximum reduction of 37 m due to a large amount of over-exploitation of groundwater. The funnel zone in Liaoyang City has an area of 254 km ~ 2 and a maximum depth of 31 m. Industrial and agricultural water contention and industrial diversion Agricultural water phenomenon. In Liaoning Province, water shortages amount to 1.6 billion m 3 per year, and by 2000 there will be more than 5 billion m 3 water shortages. If not resolved as soon as possible, it will inevitably bring about a series of social problems. At present, the water conservancy projects in the province amount to 11.3 billion cubic meters of water supply to all sectors of the national economy each year, playing the role of peak-shifting regulation in the flood season of 1985 and 1986 and reducing the direct loss by more than 1 billion yuan. In the 40 years since the founding of the People’s Republic of China, a total of over 10 droughts and floods in the province have resulted in a substantial reduction of grain output. Therefore, the rise and fall of water conservancy have a great restrictive effect on industrial and agricultural production and urban and rural construction, which determines the water conservancy industry In the national economy occupies a special position.
