Abstract: The paper takes Shandong Province as the study area because of its low per capita occupancy of water resources and unbalanced structure of water resources utilization. Firstly, the water footprint of Shandong Province during 2005-2014 and the water footprint of 17 cities in 2014 were calculated to realize the spatial-temporal analysis of the water footprint. Based on the results and DPSIR theory, a comprehensive index system was constructed. Afterwards, the factor analysis was introduced, and strength of sustainable water resources utilization in the province in 10 years was reflected by the comprehensive factor score. The comprehensive factor scores of 17 cities in 2014 were calculated and clustered with spatial and temporal analysis. The results showed that: the comprehensive score was increasing during 2005-2014, which suggested that the degree of sustainable utilization tend to be strengthened. However, the score is low in general, and the efficiency of water utilization need to be improved. The levels of sustainable water resources utilization of 17 cities in 2014 presented spatial differentiation that the east was superior to the west and the south was superior to the north.

Key words: comprehensive evaluation of factors, Shandong Province, sustainable utilization of water resources, water footprint
