Vulnerability Assessment of Regional Water Resources

Abstract

This paper established the regional water resources vulnerability impact factor system by selecting the impact factors and screening out the key factors based on principal component analysis and DPSIR model. Then combing with multipolar fuzzy pattern recognition model and improved fuzzy clustering iterative model, the regional water resource vulnerability assessment model was proposed. Taking Jinan city as an example, the results of water resource vulnerability assessment from 2000 to 2016 show that the water resource status of Jinan city has gone from bad to good, then to worse, and finally slowly getting better.
