Research on the Cultural Loss and Migration Strategy of EDPs in Predicament Based on Fuzzy Comprehensive Evaluation and BP Neural Network

Sea level is rising. Coastal areas and island countries are at risk of complete disappearance, and climate refugees may be in predicament. On the basis of this fact, in this article we use BP neural network to estimate the number and distribution of EDPs. The fuzzy comprehensive evaluation model is used to quantify the risk of cultural loss in different countries and evaluate the risk level in the South Pacific. We determine the global migration policy of EDPs through the TOPSIS model, and a migration policy plan is proposed with New Zealand, Australia, and China as host countries. Considering cultural protection and human rights, this study constructs a risk warning and migration system for the EDPs predicament and provides a reference for the migration of EDPs.
