Mount Qingcheng and the Dujiangyan Irrigation System Trip this weekend was one of the most incredible scenic areas i have ever seen.Both Mount Qingcheng and the Dujiangyan Irrigation System are located west of Chengdu, the capital city of Sichuan Province. Mount Qingcheng, known as the fifth among the most famous Taoist mountains of China.
The Dujiangyan Irrigation System built over 2,200 years ago, it still provides benefits for the people. The irrigation system was erected on the Minjiang River at the foot of Yulei Mountain.Here the Minjiang River, after being joined by many tributaries in its upper reaches, runs toward the Chengdu Plain. As the Yulei Mountain originally blocked the river so that water could not flow eastward, the plain had no access to river irrigation and agricultural development in the region was therefore seriously affected. Li Bing, governor of Shu Prefecture during the Warring States period (475-221 BC), made a careful survey of the region and then had a channel cut through Yulei Mountain. He put a dyke in the middle of the Minjiang River to divide it into two parts. This happened about 250 BC. He also ordered the local people to open channels and canals on the plain so as to divert the river for irrigation purposes. This finally turned the agricultural potential of the plain into a land of abundance.
The ancient Dujiangyan Irrigation System is unique and a scientific marvel. It provides the vital passage that joins mountain and plain. The main system consists of three parts: a fish-mouth-like water-dividing dyke, two spillways for discharging flood waters and silt, and a channel cut through Yulei Mountain as a water inlet. These three parts interact and depend on one another, constituting a carefully designed and reasonably arranged water diversion hub that contributes to irrigation, flood control, and shipping.
