Xiangjiaba hydropower station is the last hydropower station in Jinsha River hydropower base built by Three Gorges Group. Located in the lower reaches of Jinsha River at the junction of Xuzhou District, Yibin City, Sichuan Province and Shuifu City, Yunnan Province, it is 35 kilometers away from Yibin City, but only 1.500 meters away from Shuifu City. It is a giant hydropower station that mainly generates electricity and gives consideration to the comprehensive benefits of flood control, sand blocking, irrigation and shipping.
Looking at such a magnificent hydropower station and the lush Jinsha River, my heart is full of pride and pride. Jinsha River is the name of the upper reaches of the Yangtze River, named after the yellow sand in the river. It is the boundary river between Sichuan, Tibet and Yunnan provinces.
The first time I saw the Jinsha River was during my trip to Tibet in Yunnan. The roaring Jinsha River is like a golden dragon that I can't forget for a long time.
However, it never occurred to me that the Yibin section of Jinsha River, which is famous for its stormy waves, will undergo great changes after Xiangjiaba impoundment. "Jinlong becomes Qinglong", and the Jinsha River passes through Yibin with unique scenery.
According to the data, the middle reaches of Jinsha River is one of the main sediment-producing areas of Yangtze River, which is about 1/2 of the sediment discharged into Three Gorges Reservoir. With the completion of Xiluodu Hydropower Station and Xiangjiaba Hydropower Station, sediment deposition, the biggest heart disease of the Three Gorges, has been basically solved, which also makes the Jinsha River Road passing through Yibin section more and more clear.
According to the local people, as early as 20 12, the river scenery in Yibin has undergone great changes. The clear Minjiang River and the once yellowed Jinsha River, a distinctive and unique landscape, have disappeared and become two intertwined "Qinglong" rolling eastward. All these beautiful scenery are attributed to the completion of Xiangjiaba Hydropower Station.
But in addition to Yibin's unique scenery, the water city on the other side is also impressive. Shuifu City is located in the northernmost part of Yunnan, at the intersection of Jinsha River, Hengjiang River and Yangtze River, across the river from Xuzhou District, Yibin City, Sichuan Province. In addition to Xiangjiaba Hydropower Station, there is Zhang Wo Hydropower Station in Shuifu City.
Standing in Xuzhou District, Yibin City, Sichuan Province, this water-rich city looks like a "semi-circular island". Although it is not big, it is remarkable to have the largest port in Yunnan, the port rich in water and the first thousand-ton direct port on the Yangtze River.
2065438+September 7, 2008, Shuifu County was established as a city, and Yunnan Province was directly under the jurisdiction of Zhaotong City. Water is rich in the northeast, low in the southwest and high in the southwest, with many scenery. In addition to Xiangjiaba Hydropower Station, Shuifu City also has the Grand Canyon West Hot Spring and Tongluoba National Forest Park.
The completion of Xiangjiaba Hydropower Station has brought closer ties between Yunnan and Sichuan. Yibin and Shuifu are like brothers and have a grand vision of "destiny, common development and bright future". It is said that the name Xiangjiaba has a history of about 400 years.
At the beginning of the Qing Dynasty, Xiang moved here because of the vast lakes and mountains, hence the name Xiangjiaba. The name "Xiangjiaba Hydropower Station" came from this.
Xiangjiaba hydropower station dam is a concrete gravity dam, with a height of 384m, a maximum dam height of162m, a dam crest length of 909.26m, a controlled drainage area of 458,800 square kilometers at the dam site, a total reservoir capacity of 5163 million cubic meters, a regulated storage capacity of 900 million cubic meters and a backwater length of156.6km.. ..
As a dam for building a ship lift in Jinsha River hydropower base, its ship lift is the largest single ship lift in the world, and its scale is equivalent to that of the Three Gorges. It only takes 15 minutes for a thousand-ton ship to cross the dam. This efficiency far exceeds that of the Three Gorges Five-level Ship Lock (the average dam crossing time of the Three Gorges Ship Lock is 5 hours).
At the same time, Xiangjiaba Xiluodu Hydropower Station has a total power generation capacity greater than that of the Three Gorges Hydropower Station, and a single 800,000-kilowatt hydro-generator set ranks first in the world, and its installed capacity is second only to the Three Gorges and Xiluodu Hydropower Stations.
On the drive to the observation deck of Xiangjiaba Hydropower Station, I saw the beautiful scenery on the road. The reservoir is like a "high gorge out of Pinghu". Under this "high lake", many places and cultivated land have been flooded.
Under the reservoir, the ancient sites such as Dongxiang, Yanfu Town, Jinping Town (formerly Pingshan County), Xin 'an Town, Xincheng, and Zhoushan Road in Jinsha River, which were dug more than 800 years ago, have all sunk into the bottom of the river. Today, the living environment of people on both sides of the strait is the later relocation site, and their living environment and conditions are soaring.
