China Three Gorges Group puts ecological value and ecological protection on the same level as engineering construction, and strives to implement the green development concept of green mountains and green mountains, which is a combination of the protection of natural resources in the river basin and reasonable development and utilization, and actively explores ecological protection. And repair new roads, strengthen habitat protection, protect rare animals and plants, continue to implement soil and water conservation and ecological restoration, and achieve harmony between man and nature.
In the environmental protection work of the Three Gorges Project, a long-term environmental research demonstration was carried out in the planning and design stage; during the construction of the project, the environmental protection work in the construction area was strictly implemented. Species-focused protection of terrestrial species; carried out species protection work for Chinese sturgeon, Yangtze finless porpoise and fishes of the Yangtze River Construction; long-term continuous expansion and release; actively promote the research and practice of ecological fisheries in the Three Gorges Reservoir; carry out experimental work on ecological regulation of the reservoir; establish and operate the ecological and environmental monitoring system of the Three Gorges Project; actively carry out the follow-up environmental protection work of the Three Gorges Project. During the development of cascade hydropower in the lower reaches of the Jinsha River, the overall planning and layout of fish habitat protection in the lower reaches of the Jinsha River will be systematically protected, and natural habitats will be systematically cooperated with the Ministry of Agriculture and Rural Affairs to fully cooperate in aquatic ecological protection work. Strict implementation of habitat improvement and impact mitigation measures. Xiluodu designed and built multi-layer water abstraction facilities. Baihe Beach and Wudongde implemented multi-layer water abstraction and fish passing facilities design, and carried out ecological restoration of Heishui River. A network of environmental monitoring stations in the lower reaches of the Jinsha River; surveys of habitats and spawning grounds of rare and endemic fish, research on life history and natural reproduction scale, research on domestication technology, research on artificial reproduction technology, and research on large-scale seed breeding technology .
Chinese sturgeon proliferation and drainage and watershed protection
On April 14, 2018, the "2018 Yangtze River Three Gorges Chinese Sturgeon Releasing Event" sponsored by China Yangtze River Three Gorges Group Co., Ltd., the Yangtze River Basin Fishery Supervision and Administration Office of the Ministry of Agriculture and Rural Affairs, the Hubei Provincial Department of Agriculture and the Yichang Municipal Government was held in Yichang Successfully held, 500 Chinese sturgeon were released to the Yangtze River. This activity is the 60th continuous release of Chinese sturgeon since its establishment.
The Chinese sturgeon release group includes 5 age echelons, which is the richest age echelon in the history of Chinese sturgeon release, and it has a systematic supplementary effect on the wild resources of Chinese sturgeon. Up to now, the Chinese sturgeon research institute has released more than 5 million Chinese sturgeons to the Yangtze River. In order to scientifically answer the effects of the release of Chinese sturgeon, scientific researchers have integrated sonar monitoring, Internet and wireless transmission and other technologies to establish a monitoring system for the release of Chinese sturgeon from Yichang to the estuary, covering 1800 kilometers in the middle and lower reaches of the Yangtze River. This is the current domestic coverage. The widest and most comprehensive real-time monitoring and evaluation system for fish release effects. The latest monitoring research results show that the percentage of Chinese sturgeon entering the estuary waters in recent years is 53.7%, which has played an important role in supplementing the natural resources of Chinese sturgeon.
Three Gorges Endemic Rare Species Protection
Through careful research and careful maintenance, China Three Gorges Group has created a suitable living environment for endangered species and created a "rare botanical garden" and a fish protection center. The Group's Yangtze River Rare Plant Research Institute has continued to carry out work on the protection and research of the Three Gorges' unique and rare plants. Since 2007, it has continued to investigate the wild plant resources in the Yangtze River Basin. Reproduction of unique rare plants, cooperation or independent development of ecological protection projects in the Yangtze River Basin. In 2017, the Yangtze River Rare Fish Conservation Center, a new fish protection base, has completed its scientific research and breeding area and experimental work area.
