Because that Qingpu is the location of drinking water source of Shanghai, it is very important to keep the quality of its water environment.On the basis of in-depth discussion of the theory of water environment carrying capacity, this paper focus on the research of water environment carrying capacity with the combination of sustainable development theory and "nature-economy-society complex system "theory. By analyzing the current situation of water environment of Qingpu, this paper set up sustainable water environment carrying capacity target system according to its actual situation, then, calculating the water environment carrying capacity with the method of AHP.
