Comprehensive evaluation of the eco-environmental vulnerability in the Yellow River Delta wetland

The eco-environmental vulnerability is an important indicator of the development in wetland. However, the vulnerability is influenced by various interacting factors. The interaction among these factors is fuzzy and stochastic, making it difficult to describe the evaluation results accurately and qua...

The results, compared with the catastrophe progression method, are valid. The research results provide technical support for the comprehensive evaluation of eco-environmental vulnerability in wetland.
