摘要
本文根据文献[1]提出的相对隶属度概念和模糊模式识别理论,讨论了相对隶属度及模糊模式识别用于自然灾害危害度评价的原理和过程,并结合贵州毕节地区泥石流危害度评价,阐述相对隶属度和模糊模式识别用于自然灾害危害度评价的合理性和可行性,收到满意的效果。
According to the concept of relative grade of membership and the theory of fuzzy pattern recognition model (FPRM), which is put forward by Professor Chen, this paper discusses the principle and process of using the FPRM for appraising the endangering degree of natural disasters.A real example of assessing the disaster degree of debris flow in Bijie region is given. Some accurate assessment results are obtained.
