First Phase Project of Western Route of South to North Water Transfer Project is a great water transfer project that transfers water resources from upper branches of the Yangtze River to upper reach of the Yellow River, and it bears great important practical significance to carry thorough and systematic research on runoff characteristic and supply risk of the water resources source system.

Ecological risk analysis and evaluation of water resources system:A case study of Xiangride oasis;

Theory, development and application of the conditional simulation in water resources system;

Evaluation of vulnerability of regional water resources system based on the fractal theory;

The paper introduces the theory of improved interpretative structural modeling and analyzes the structuralstratum of factors that affect water resource system.

The risk of water resources system refers to a specified temporal and spatial environment condition in general that unexpected uncertain events happened in the system, such as uncertain events of potential unfavorable effects or imperiling to the safety of people s life, property and health and ecological environment.
