Analysis about Different Regional Geological Hazard Assessment Applications
摘要
Abstract
Geological hazard is a very complicated nature phenomenon. The major assessment idea at home and abroad currently is to establish the assessment model based on the application. However, it causes the insuperable "incompatibilities" which can be reduced by this kind of application. The assessment mode of associating different applications is very important. By analyzing the suitability of existing assessment applications, this paper proposed the principles which applied those kinds of associating assessment modes according to their different strengths and weaknesses, based on the principle of developing its advantages and avoiding disadvantages, principle of mutual development, principle of increasing the efficiency of the information, and the principle of improving the accuracy of assessment results. Through the example of regional landslide hazard assessment of Qingchuan County, this paper analyzed the application of those principles to assess the regional hazard risk with the associating assessment mode. The result showed that the associating assessment modes which the fuzzy comprehensive assessment combined with the AHP and the entropy theory respectively own a higher accuracy than the fuzzy comprehensive assessment separately. However, because of the insufficient historical monitoring data, the accuracy of the assessment result which was obtained by the associating application of fuzzy comprehensive assessment and AHP was higher than the one which was obtained by the fuzzy comprehensive assessment model combined with the entropy theory.关键词
