英文摘要	In this research, a hybrid Geographic Information System (GIS)-based watershed-scale inexact optimization approach was developed to identify the optimal spatially distributed network of constructed wetlands for NPS pollution control. Such an approach combined the GIS technology and fuzzy-stochastic two-stage programming (FSTP) into a general optimization framework. A GIS-based compound topographic index (CTI) was used to identify potential wetland sites at thewatershed-scale, a GIS-based export coefficient model (ECM) was employed to estimate the nutrient load from NPS pollution, and the FSTP was used to map the optimal spatially distributed network of constructed wetlands for reducing the NPS pollution with the minimization of system costs under uncertainty. As an integration of two-stage stochastic programming (TSP) and fuzzy credibility chance-constrained programming (FCCP), FSTP can not only address dual uncertainties expressed as probability density functions and fuzzy membership functions but also provide an effective linkage between the pre-regulated management policies and the associated economic implications. The developed modeling system was applied to the planning of wetland network installation in the Songhuaba watershed, China. The optimization results can help watershed managers to obtain desired plans of wetland siting, and nutrient permit allocation for sub-basins under different confidence levels.
