成都-都江堰景区-70
Chengdu

都江堰(Dujiang yàn),位于四川省都江堰市城西,是中国古代建设并使用至今的大型水利工程,被誉为“世界水利文化的鼻祖”,是四川著名的旅游胜地。通常认为,都江堰水 利工程是由秦国蜀郡太守李冰及其子率众于前256年左右修建的,是全世界迄今为止,年代最久、唯一留存、以无坝引水为特征的宏大水利工程,属全国重点文物 保护单位。

李冰父子邀集了许多有治水经验的农民,对地形和水情作了实地勘察,决心凿穿玉垒山引水。由于当时还未发明火药,李冰便以火烧石,使岩石爆裂,终于在 玉垒山凿出了一个宽20公尺,高40公尺,长80公尺的山口。因其形状酷似瓶口,故取名“宝瓶口”,把开凿玉垒山分离的石堆叫“离堆”。

之所以要修宝瓶口,是因为只有打通玉垒山,使岷江水能够畅通流向东边,才可以减少西边的江水的流量,使西边的江水不再泛滥,同时也能解除东边地区的干旱,使滔滔江水流入旱区,灌溉那里的良田。这是治水患的关键环节,也是都江堰工程的第一步。
