没有水,地球就会象人类已知的其它星球那样,呈现一派荒芜凄凉的景象;没有水,就没有人类的产生与发展,没有社会的文明与进步。水是生命的源泉,是大自然赋予人类最可宝贵的资源。从大禹治水算起,中华民族已有4000余年的水利史。当今地球上出现了世界性的淡水资源危机和水体污染,严重损害了地球生态系统的平衡和稳定,威胁着人类的生存和社会发展。我国的水问题也紧迫地摆在我们面前。
Without water, the Earth will appear like a desolate and desolate landscape like the other planets known to mankind. Without it, there will be no human existence and development and no social civilization and progress. Water is the source of life and the most precious resource that nature has given humankind. Since Dayu flood control, the Chinese nation has more than 4,000 years of water conservancy history. Today, there is a worldwide crisis of freshwater resources and water pollution on the earth, which has seriously damaged the balance and stability of the earth’s ecosystem and threatened the survival and social development of mankind. The water problem of our country is also urgently before us.
