Water resources are basic natural resources and strategic economic resources. As one of the important cities of southeast coastal China, the rapid development of economy and society has caused unprecedented pressure to the sustainable utilization of water resources of Quanzhou. Based on the principle of combining subjective with objective, two mathematical approaches were chosen and applied, one of which is the improved analytic hierarchy process (AHP) and the other is Cluster Analysis based on Factor Analysis in this study. The main conclusions are as following. The regions with secure water resources were Dehua County, Yongchun County and Anxi County. The regions with basically secure water resources were Nan'an City, Luojiang Borough and Quangang Borough. And the regions ranked into the categorizes of insecure water resources were Huian County, Licheng and Fengze Borough. Jinjiang City and Shishi City were the regions ranked into the categorizes of severely insecure water resources. From the year 2000 to 2004, the water resources security value had a downtrend. From 2004 to 2006, the situation had a improvement, and after that, the value began to decline again. If 2015 and 2020 are dry or extraordinary dry years, Quanzhou City would be confronted by great water stress. The factors drove the different water resources security levels for different regions were analyzed. Some measures and accesses to achieve the sustainable water resources utilization and improve the water resources security were given and proposed.
