Development of upper reaches of the Yangtse River should consider to be affected

From;  Author:Stand originally
Proposer: Chinese democracy promotes meeting Central Committee

Water of area of upper reaches of the Yangtse River can be resourceful, water can reserves occupies whole drainage area nearly 90% . Did not come 20 years, water and electricity of the Yangtse River develops advocate battlefield is in area of upper reaches of the Yangtse River, will go into operation of engineering of a batch of water and electricity is built, do affluent to will form more large-scale stair hydroelectric station in upper reaches of the Yangtse River at the appointed time group. After these hydroelectric station and reservoir investment move, produce the zoology to upper reaches of the Yangtse River and whole drainage area and environment main effect.

If show the project of water and electricity of a program to be carried out entirely, 61% what total storage capacity of reservoir of area of upper reaches of the Yangtse River will achieve discharge of river plain diameter, outside a few affluent such as river of the water that divide bare, trunk stream of upper reaches of the Yangtse River definitely most reach will bestrew stair reservoir, quite a few is natural the river will turn for half natural river or artificial pilot river, this kind of change brings the ecosystem that gives the Yangtse River and environment long-term effect.

Healthy the Yangtse River should serve for the mankind not only, and also should provide favorable environment for catchment nature ecosystem, the preserves need nature the Yangtse River of catchment hydrology loop and ecosystem. So, the water that be being developed and uses zone of upper reaches of the Yangtse River can when resource, downstream zone modes of life and relation to their environment and environment are bit more sensitive on should thorough knowledge, ecology of loop of mature place hydrology, river, aquatic content, resource, environment and humanitarian those who wait for a respect restrict an element, avoid or reduce water and electricity to develop the effect of opposite condition and environment.

The effect of zoology of region of convection of construction of hydroelectric station of stair of upper reaches of the Yangtse River and environment is very mixed, inside short time see apparent effect harder, the manner that should act on scientific deal with concrete matters relating to work is analysed objectively in the round, handle the relation of environment of good protection organisms' habits and development of water and electricity. The program that water and electricity develops, design, construction and controller should listen to the opinion of each respect extensively, encourage the public to participate in, take step as far as possible, reduce the effect of zoology of region of convection of project of water and electricity and environment, put forward as follows to suggest for this:

(1) government and relative of each the door, catchment controller, reservoir controller and other benefit should have the concept of zoology and environmental protection, realise what hydroelectric station is built and run zoology and environment to bring is adverse adequately with the influence, should realise the complexity of the problem and long-term sex at the same time.
