Abstract:

Hydroelectricity，being developed at high speed in China recently，has caused many integrated，complex and variable problems，which have attracted great attentions of many researchers.As the problems resulted from hydrostations building are integrated，complex and variable，analyzing all these problms in a dynamic and integrated way will be helpful for the comprehensive management of hydroelearicity development and combined ecosystem of the basin.Taking upper Minjiang River as an example，and based on aquatic ecosystem services，different kinds of ecological，environmental，societal and economic problems were analyzed according to the three hydro electric station building periods：before building，on building and after building periods.The conclusion is that the building of hydrostation will change not only the amount and or of river ecosystem services ，but also the accepter of these services.And further more，enormous benefits gained from hydroelectricity is at the price of the decrease even the vanishment of some ecosystem sersvices and the resulted complex social and economic problems.At last，based on the analysis，some suggestions were provided from views of government，enterprise and researcher.〖
