初三英语作文都江堰水利工程介绍
倩女幽魂°辸墜
In China,Chengdu is always praised as the Tian Fu Zhi Guo,which means 'Nature's Storehouse'.Over 2,200 years ago,the city was threatened by the frequent floods caused by flooding of the Minjiang River (a tributary of the Yangtze River ).Li Bing,a local official of Sichuan Province at that time,together with his son,decided to construct an irrigation system on the Minjiang River to prevent flooding.After a lengthy study and a lot of hard work by the local people,the great Dujiangyan Irrigation Project was completed.Since then,the Chengdu Plain has been free of flooding and the people have been living peacefully and affluently.Now,the project is honored as the 'Treasure of Sichuan',which still plays a crucial role in draining off floodwater,irrigating farms and providing water resources for more than 50 cities in the province.Dujiangyan is the oldest and only surviving no-dam irrigation and a wonder in the development of Chinese science.The project consists of three important parts,namely Yuzui,Feishayan and Baopingkou scientifically designed to automatically control the water flow of the rivers from the mountains to the plains throughout the year.Yuzui,like a big fish lying in the Minjiang River,is a watershed dividing the river into two parts:inner river and outside river.Feisha Yan is a spillway that diverts the sand and stones of the inner river into the outer river.Baoping Kou,like a neck of a bottle,is used to bring water into the inner river from Minjiang.At the same time,Baoping Kou controls the amount of the intake water due to its reasonable location.These three parts interact with each other perfectly to form an effective water conservancy project.During the low-water season,60% of the Minjiang water is brought into the inner river for irrigation while 40% of the water is drawn into the outside river.The situation is reversed in the flood season ensuring the water supply for irrigation and protection from flooding on the Chengdu Plain.更多信息请访问：/There is a magnificent bridge called the Anlan Cable Bridge crossing the Minjiang River above Yuzui,which is the most scenic place in Dujiangyan.The construction of the bridge originally commenced before the Song Dynasty (960-1279).At that time,the body of the bridge was constructed with wooden blocks and the handrails were made of bamboo.Recently the wood and bamboo were replaced with steel and reinforced concrete to ensure the security of the visitors.Seen from afar,the bridge looks like a rainbow hanging over the river.From the bridge,you can clearly see the entire layout of the Dujiangyan system.就这些,
