Dujiangyan City
county-level city in Chengdu, Sichuan Province, China
Dujiangyan (Chinese: 都江堰; pinyin: Dūjiāngyàn) is a county-level city of Sichuan Province, Southwest China. It is under the administration of the prefecture-level city of Chengdu. Its north-west region forms a border with southern Ngawa 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.
Dujiangyan was formerly a county named Guanxian or Guan County (灌县; 'irrigation county'). The county became a county-level city in 1988 and was renamed after the Dujiangyan Irrigation System, in the city's northwest, famous for providing Chengdu with water for over two millennia, since around 250 BC.
History
Around 250 BC during the Warring States period, Li Bing, a governor of Shu (present Sichuan Province) in the Qin 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 the Min 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".

Why this record matters
“Dujiangyan City” is worth following because a concise public description often conceals a longer documentary argument. Here, Dujiangyan, City and county-level provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jun 4, 2026. The linked authority identifier is Q1023900. VIAF identifies the subject as 130654766. The Library of Congress control number is nr2006002959. Authority coordinates are 30.993, 103.624. 4 of 6 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020 and 1988.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
