我国古代水利工程事业有着长期的发展历史,每一种工程的完成都在改变着自然的面貌。在一定的时代和地区内,它促进了农业生产,发展了交通运输,预防了水旱的灾害。这种工程的兴建,在春秋以前规模比较小,大规模的开凿沟渠,或建设灌溉工程,则开始于春秋末年,而大盛于战国时代。后世许多水利工程大都是在战国时的基础上不断加以整理或扩建的。尤其是春秋战国之间是中国历史上的一个大转变时期,所以这时大规模的水利工程的兴建决不是偶然的,这是我们研究春秋战国时代的水利工程特别需要注意的重要意义。春秋战国时所兴修的水利工程,有两类:一类是为了交通运输而开凿的渠道运河工程,一类是为 The cause of ancient water conservancy projects in our country has a long history of development, and the completion of each kind of project is changing the face of nature. In a certain era and region, it has promoted agricultural production, developed transportation and prevented floods and droughts. The construction of such a project was relatively small in size before the Spring and Autumn. Large-scale ditches were dug or irrigation projects were built, beginning in the late Spring and Autumn Period, while Dasheng was in the Warring States Period. Many later generations of water conservancy projects are mostly constantly consolidated or expanded on the basis of the Warring States Period. Especially between the Spring and Autumn and the Warring States Period, a period of great change in Chinese history. Therefore, the construction of large-scale water conservancy projects is by no means an accident at this time. This is of great significance for us to pay particular attention to in the hydraulic engineering of the Spring and Autumn Period and the Warring States Period. Spring and Autumn and the Warring States period when the water conservancy projects, there are two categories: one is for transport and channeling canal project, one is for
