坎儿井(Karez)是新疆干旱地区的一种水利系统，由地下渠道将水井连接而成。该系统将春夏季节渗入(seep into)地下的大量雨水及积雪融水收集起来，通过山体的自然坡度引到地面，用于灌溉农田和满足人们的日常用水需求。坎儿井减少了水在地面的蒸发(evaporation)，对地表破坏很小，因而有效地保护了自然资源与生态环境。坎儿井体现了我国人民与自然和谐共存的智慧，是对人类文明的一大贡献。

Karez is a water conservancy system found in the dry region of Xinjiang, in which underground channels join wells to-gether. The system collects a large amount of rainwater and melted snow water that seep underground, and drains the water to the ground by the natural mountain slope for the irrigation of fields and the daily use. Karez reduces the evap-oration on the ground and does little harm to the surface, thus protecting natural resources and the ecological envi-ronment effectively. The system embodies the Chinese wisdom that people and nature co-exist in harmony, and is well recognized as a major contribution to the human civili-zation.

Located on the Minjiang River in the west of the Chengdu Plain，Dujiangyan is about 50 kilometers away from Chengdu City，which was built in the third century BC.

As the oldest water control project in the world，the Dujiangyan Project embodies the wisdom of the harmonious coexistence of our people and nature，which is still in use and can control water without any blocking dam.
