Development history

Ertan National Forest Park originates from the Yalong River in the Bayan Har mountains of the Qinghai Tibet Plateau. Many beaches have been formed along the way. After the Yalong River enters the territory of Yanbian, a beach is formed at the intersection of the Yalong River and the Hongni river. The local villagers call it toutan. Then they go down into the original Jinhe Township and form another beach. People call it Ertan, and then down there are three beaches. The dam site of Ertan Hydropower Station is built in Ertan. The surging Yalong River flows here like a shiver. It is intercepted by the 240 meter high dam, and then it pours down from the spillway tunnel. Ertan Hydropower Station is the largest hydropower station built in China in the 20th century. The construction of the main project started in September 1991, the river was successfully cut off in November 1993, and the first unit was connected to the grid in August 1998. The normal water level of the power station reservoir is 1200 meters, with a total capacity of 5.8 billion cubic meters. The overflow parabolic double curvature arch dam ranks first in Asia, with an installed capacity of 3.3 million kilowatts and an annual power generation of 17 billion kilowatts.

With the completion of Ertan Hydropower Station, Ertan National Forest Park is composed of Ertan Hydropower Station Reservoir and large mountains and forests around the reservoir area. The magnificent power station, the vast blue lake, the green mountains around, the wild primeval forest, the beautiful 8 small islands in the lake and the strange customs of more than 10 ethnic minorities living nearby make Ertan National Forest Park secluded The quiet environment, suitable climate and fresh air make it an ideal tourist area for tourism, exploration, wind gathering, entertainment, vacation and recuperation.
