Vulnerability Assessment of Regional Geological Disasters Based on Unascertained Measurement Theory

Based on unascertained measurement theory, a comprehensive evaluation method to propose the vulnerability of regional geological disasters was presented in this paper. The function of unascertained measure of all evaluation indexes was established, the weights for indexes was calculated by entropy weight theory, and a result of the vulnerability of regional geological disasters has been carried out using the rules of credible recognition. This method can solve a lot of unascertained problems in comprehensive evaluation the vulnerability of regional geological disasters, and also can analyse the vulnerability of regional geological disasters objectively. Furthermore, using listed 40 the regions as samples, the effectiveness were discussed by the aid of comparison with the results of comprehensive index method. The research results show that the comprehensive evaluation method of unascertained measurement presents excellent performance, high accuracy and it thus has wide applying prospect, it is an effective new way to evaluate the vulnerability of regional geological disasters.
