Abstract

We developed a spatially explicit method to examine the effects of urbanisation on ecosystem service values. Especially, a spatially explicit urban growth model was developed through incorporating a macro-scale model (system dynamics) and a micro-scale model (CLUE-S). In addition, spatially explicit ecosystem service values were simulated under three socio-economic scenarios: (1) current economic growth, (2) rapid economic growth, and (3) sustainable economic growth. Analysis of results suggests that the degradation of ecosystem functions is associated with the conversion from water body and farmland to built-up and barren lands. Moreover, obvious spatial variations were found associated with ecosystem service values.
