(6) Ecological and environmental protection technologies for hydropower project
Huaneng Lancang River Hydropower Co. has made huge investment in construction of ecological protection forest along Lancang River, intended to improve soil and water loss treatment and vegetation recovery, to build proliferation stations for rare fishes, rescue stations for wild animals, and botanic gardens for rare plants, and to protect local ecological environment and biodiversity. Nuozhadu Hydropower Station is a good example for ecological and environmental protection during hydropower development. The Station conducts treatment on water and soil loss for nearly 900 thousand m2, and recovers vegetation for nearly 800 thousand m2. Over 10000 national protected plants are grown in the rare plant garden. Over 30 thousand wild fishes have been proliferated and released from the proliferation station. And 44 animals have been rescued and temporarily raised in the wild animal rescue station. At Gongguoqiao Hydropower Station, over 30 million RMB has been invested in the fish proliferation station, with a plan to release over 330 thousand fishes each year. In 2012, Huaneng Lancang River Hydropower Co. demolished the cascade power stations on Jidu River, and recovered the natural river courses and protected the aquatic resources by building new fish habitats.
