With the socio-economic development, water demand is increasing, and the conllicts between water supply and water demand at regional scales become increasingly significant. Scientific evaluation on the risk that caused by the conllicts between supply and demand of water resources is essential to the elimination of the imbalance. This paper analyzes the utilization of water resources in the Songliao Basin based on the water quantity, water quality and socio-economic data in 1999-2006, and generates a risk evaluation index system of water resources utilization, which included 10 indicators. Three common factors including high water demand, high water supply and low-quality water were used in factor analysis. The three common factors were assessed with spatial clustering, and the risk distribution of water resources in the Songliao Basin was estimated. The research results show that the pattern of water resource utilization in the Songliao Basin is that high risks is in the center, with low risk around the basin. Nen River and Songhua River have high risks and Tumen River and Wusuli River have low risks.

Key words: factor analysis, risk assessment, Songliao Basin, spatialcluster, water resources utilization
