Abstract According to the ecosystem assessment framework developed by the Millennium Ecosystem Assessment (MA), this paper designs an evaluation system of ecosystem services in Poyang Lake area. On the basis of relevant variables disaggregated to 1 km grid using the gridded 1 km, this paper employs factor analysis to extract a number of factors which characterize the ecosystem services of Poyang Lake area. The extracted principal component are then represented onto 1 km×1 km grids by spatial clustering analysis to recognize and identify the minimal but consistent mapping units for ecosystem services which can be used to delimit the boundaries of ecological service zones. The research identifies ten ecosystem service zones in Poyang Lake area according to the consistent principle of core ecosystem service unit. Four kinds of core ecosystem services including supporting function, provisioning function, regulating function and cultural function are identified and represented. The research results could provide both spatially and temporally valuable decision-making information for sustainable ecosystem management in the targeted area.
