Description
Technical field
The utility model is related to a kind of dam, more particularly to a kind of dam for the conservation of nature ecosystem.
Background technology
The Changjiang river is third place in the world great river, the great river of Asia first, and the natural fish storehouse of China was once described as a long time.However as length
The construction of a large amount of Hydropower Dams on river, the Changjiang river fish are severely impacted, and the ecosystem faces collapse.
The Changjiang river is third place in the world great river, the great river of Asia first, and the natural fish storehouse of China was once described as a long time.However as length
The construction of a large amount of Hydropower Dams on river, the Changjiang river fish are severely impacted, and the ecosystem faces collapse.
Fish are one of key links of biological chain on the Changjiang river, and without fish, other animals made a living with fish are just by nothing
Method is survived.There is no fish to eat up the planktonic organism in water body, water body will also lose an important self-purification function.If fish are gone out
Absolutely, the species diversity and ecosystem of the whole Yangtze river basin just face collapse.
In June, 2013, when Upper Yangtze River joint scientific investigation group carries out fishery resources sampling in Jinsha jiang River upstream, though early have psychology
Prepare, but result still allows them to be shocked：Three stock of fish samplings only find 17 kinds of fish samples, wherein also 3
Alien species are planted, and Drainage Area of Jinsha River monitoring fish have 143 kinds in history.
Whole the Changjiang river also how many fish on earth, in the case where related scientific research is lacked, with catch over the years or has some idea of.
The data that long fishing committee provides shows that 1954, fishery quantity of the catch in the Yangtze river basin was 430,000 tons, and 1955-1971 fishes for production every year
260,000 tons are measured, is just begun to decline thereafter, to the 1980's, fish crop is fluctuated at 200,000 tons or so every year, and nineteen ninety is for fish crop
The about half of the eighties, and by 2011, amount of fishing was less than 100,000 tons.
More specifically data are：The stocks of fish such as Changjiang River Estuary knife long-tailed anchovy, long-tail anchovy drastically fail, knife long-tailed anchovy by 2001 694
Ton drops to 50 tons in 2011, long-tail anchovy yield also dropped to by 1182 in 2001 tons 2011 less than 50 tons, and once
The Changjiang river hilsa herring first of " the Changjiang river three delicacies " is ranked, annual production is up to 1600 tons, disappeared substantially now, filefish, megalobrama amblycephala, length
Also difficulty has sought trace for river hairtail, Pelteobagrus fulvidraco, mandarin sturgeon etc..
It can thus be seen that the resource situation of each species fails comprehensively in the aquatic biological chain in the Changjiang river, whole the Changjiang river
The ecological environment in waters is greatly destroyed.
The expert of the Changjiang river aquatic products research institute thinks that in the factors for threatening fish, hydroelectric project is topmost.Though
Right overfishing and water pollution also have an impact to the Changjiang river fish quantity, but as long as keeping the Changjiang river connective, and fish at least can be with
Selection migration is fished for and water pollution to hide, and Hydropower Dam can destroy Habitat for Fish, and migration is blocked logical in destruction spawning place
Road, thoroughly chops the lifeline of fish off.
Similar the problem of, also embodies in other regional dams, and therefore, needing one kind badly at present can allow fish to swim go back to upstream
Dam.
