The initial results of the ecological restoration of the band of the zone of the Three Gorges Reservoir District

Test plants renewed after the water flooded

Recently, the Ecological Repair Pilot Zone of the Three Gorges Reservoir area -the island of the island of Maoping Town, Mao, Hubei Province, Hubei Province, in Maoping Town, Hubei Province, showing a new look. The previous bald disappearance bands were covered with drought -resistant green vegetation, showing a harmonious green ecological picture.

The reservoir disappearance belt is a special area of ​​the reservoir's seasonal water level and the surrounding area of ​​the surrounding area. Every summer, the water level in the Three Gorges Reservoir will disappear to 145 meters due to flood prevention. After September, the dam storage water to 175 meters. Accompanied by the changes in the water level, the removal zone with a vertical height difference of 30 meters on both sides of the river was formed. When the water level disappears in summer, the yellow -brown mountains exposed outside are lacking vegetation protection. The greening of the anti -fall band is of great significance for maintaining the ecological balance of the warehouse area. This requires finding a plant -not only to resist drought and water tolerance to adapt to the growth environment of water levels and changes.

The Three Gorges Reservoir area is an important ecological barrier in the upper reaches of the Yangtze River. The Yangtze Rare Plants Institute used Yiyanzi as the pilot area of ​​the ecological restoration of the Three Gorges Reservoir area. After the water level of the Three Gorges Reservoir fell as high as 155 meters, it was between the Three Gorges Reservoir partial rocks from 155 meters to 175 meters. Plant coverage mode of perennial herb+shrub "is performed. At the same time, the study of ecological restoration in the Three Gorges Reservoir area was carried out, and water -resistant plant screening tests carried out in the Three Gorges Reservoir made progress. Through a variety of ecological repair tests, the methods and ways of eliminating the ecological restoration of the disappear are continuously explored. For more than four years, the 7,000 square meters of ecological restoration test and demonstration area has been successfully built, allowing the breeding of rare plant seedlings to return to the Yangtze River.

"We build a stone cage gear to the wall on the slopes between 155 meters and 175 meters. Put the ecological bags filled with soil and seeds on the disappearance band, and then use the anchor rod to hang the slope to fix the ecological bags to fix the ecological bag , The developed root system of plant growth can be preserved in turn to promote the soil of the disappearing band. "Qiu Liven, the head of the Ecological Repair Research Office of the Yangtze Rare Plant Research Institute, introduced it at the scene," We also targeted the trees, shrubs, and herbs 20 A variety of flood -resistant plants, try different plants in different high programs, are planted in a demonstration area of ​​the elimination belt ecological repair. The survival rate of perennial herbaceous plants is more than 90%, and the survival rate of water flood -resistant shrubs is more than 75%. "

Test plants renewed after the water flooded

According to reports, since May 2018, the Three Gorges Group's Yangtze Rare Botanical Research Institute combines the protection and reasonable development and utilization of watershed species to actively explore the new technologies and reimbursement of the Three Gorges Reservoir area, attach importance to the protection of habitats, and continue to continue Implement ecological restoration and build a natural ecosystem where human beings are harmonious with nature. At present, the ecological restoration of the pointer's disappearance belt has begun to achieve the initial results, laying a solid foundation for the renovation of the falling belt and the return of rare plants from the Yangtze River to the Yangtze River.
