The main effects of the ThreeGorges Dam to the resources and ecological environment in the drowned district and near the reservior are thosethat the land resourse is submerged and won't be recovered

natural landscape and cultural resourse are lost and won't be retrieved

factory andmine loss a lot

if rebuilt

a chained evil consequence would occur

slopeslides and collapses could impact the reservior

the reproduction of thefour major housefish would be restrained

the possibility to induce earthquake in the reservior would be made

migrating in exploiting around thereservior would cause various kind of unfavourable consequences

to theresources and ecological environment on upper reaches

soil loss wouldshorten the using time of the reservior

the deposition from the damconstruction would influence shipping

possibility to cause flood disasteron upper reaches would be made

decrease of the fish in variety andnumber

which is accustomed to live in torrent

would be produced; tothe lower and middle reaches

the effect are mainly on floodng and waterlogging prevention

the living of precious water animals and fishspecieses

the fish production at river outlet and near sea district

industry and agriculture from salt water

accumulation and erosion of the seabank at outlet and delta

the shipping at outlet and in down reaches.These effects above mentioned are profound and rigorous

some are insidious

changable and cann't be evaluated in short term. Thus

it is acritical strategy related to the development of national economy and thedestiny of descendants that whether the Three Gorges Dam is constructed

which ought to be considbred cautiously

but never be made the policymaking by few departments or persons.
