Five qualitative and four quantitative indicators were put forward through system analysis for the selection of table-water resources. The four quantitative indicators are average water quality index, the lowest month average discharge in ten years, the distance of water transfer, and investment. The five qualitative indicators include river landform, easy degree of protect water resource, influencing degree for the development of economy, the risk of water resource pollution and influencing degree for shipping, which are quantified using expert-evaluation method. Combined with a multi-target system fuzzy optimization model, these nine indicators are applied to selecting a new table-water supply resource in Foshan City. The results suggest that the combination of the nine indicators and the model of multi-target system fuzzy optimization is an efficient method for the selection of table-water resources.
