摘要
To simplify the variables and data structure, and ensure the minimum loss of original data, a Principal Component Analysis-based safety evaluation model was put forward on geological environment in earthquake region, with integrated variables to replace the original multi-dimensional variables. By constructing a safety indicator system and hierarchy of geological environment in earthquake region, the fuzzy decision-making mapping and judgment matrix was established for the geological environment safety, and with Principal Component Analysis, the principal component scores and comprehensive evaluation were determined for the observed objects; Integrated with implied entropy information in observed objects, evaluation model was proposed on the safety on geological environment in earthquake region. Case showed that model had a good effect in dimensionality reduction, which objectively reflected the safety evaluation characteristics of the observed objects and the system about the regional geological environment.
