西班牙阿拉贡地区水利开发历史悠久,留下了不少景色优美的名胜古迹。许多水利工程仅存遗迹,其用途难以辨明,还有一些遗址为后来的修复或重建工程所掩盖。但是,在某些情况下,完整的水利工程实际上得以保留原貌,因此就非常真实地反映了每个历史时期大型工程的情况,可以得知当时可能最高的技术水平与采用的技术。 Aragon region of Spain has a long history of water conservancy development, leaving a lot of scenic spots and historical sites. Many of the remaining water conservancy projects remain illustrious, their use difficult to discern, and some of the sites are covered up by later restoration or redevelopment projects. However, in some cases, the intact water conservancy project can actually retain its original appearance. Therefore, it can very truly reflect the situation of large-scale projects in each historical period. It can know the highest technical level and technologies adopted at that time.
