中国治水历史悠久,举世闻名的都江堰工程至今经久不衰,为民造福,但新中国成立以前,水利基础设施廖廖可数。新中国成立以后,水利经过半个世纪的建设,历经了开国治水和改革兴水两个不同的历史阶段,水利基础设施建设已初具规模,水利事业成就辉煌,发挥了巨大的综合效益。但进入90年代,水旱灾害和水污染频繁发生,水多、水少、水脏与水环境恶化三大灾害中干旱缺水与水污染问题越来越严重。洪涝灾害历来是中华民族的心腹之患,进入21世纪我们仍然不能掉以轻心,但由于中国特定的自然地理和气候条件,决定了洪涝灾害的长期性,因此,防洪减灾是一项长期的任务。
The flood control in China has a long history and the world-famous Dujiangyan Project has been enduring so far for the benefit of the people. However, until the founding of New China, there were ample water conservancy infrastructures. After the founding of new China, after half a century of construction, water conservancy has gone through two distinct historical stages of watering up and water reform. The construction of water conservancy infrastructure has begun to take shape and the water conservancy has achieved brilliant achievements and exerted tremendous comprehensive benefits. However, in the 1990s, floods and droughts and water pollution frequently occurred. The problems of drought, water shortage and water pollution in the three major disasters, such as water pollution, water pollution and water environment deterioration, have become more and more serious. Flood disasters have always been a confidant phenomenon for the Chinese nation. We can not afford to be lighthearted in the 21st century. However, due to the specific natural and climatic conditions in China, which determine the long-term flood disaster, flood control and disaster reduction are long-term tasks.
