Dujiangyan (Chinese:都江堰;pinyin:Dūjiāngyàn) is acounty-level city ofSichuan Province,Southwest China, it is under theadministration of theprefecture-level city ofChengdu. Its north-west region forms a border with southernNgawa Tibetan and Qiang Autonomous Prefecture. It has an area of 1,208 km2 (466 sq mi) and had a population of 710,056 in 2020.[1]
Dujiangyan was formerly a county namedGuanxian orGuan County (灌县; 'irrigation county'). The county became a county-level city in 1988 and was renamed after theDujiangyan Irrigation System, in the city's northwest, famous for providingChengdu with water for over two millennia, since around 250 BC.
Around 250 BC during theWarring States period,Li Bing, a governor of Shu (presentSichuan Province) in theQin state with his son directed the construction of Dujiangyan. Li Bing gave up the old ways of dam building, which were simply directed at flood control, employing a new method of channeling and dividing the water of theMin River. He accomplished this by separating the project into two main parts: the headwork and the irrigation system. The whole system has functioned for 2,000 years, preventing floods and providing substantial irrigation and facilitating shipping and wood drifting. It has contributed greatly to the richness of Chengdu Plain with its reputation as "The Land of Abundance".[citation needed]
On 12 May 2008, the city was the closest to theepicenter of the2008 Sichuan earthquake and the city suffered severe damage. Xinjian Primary School, Juyuan Middle School, and Xiang'e Middle School collapsed in the earthquake.[2][3][4]
