摘要
本文以新疆地区大量的破坏性地震的震害调查为基础资料,应用模糊信息分析理论评价了破坏性地震震害面积。采用信息分配概念直接形成震害面积与震级之间的二维经验关系。采用推算法则以及信息集中概念,做出Ⅰ≥Ⅵ、Ⅴ、Ⅵ、…、度在各震级Mi=4.9、5.4、5.9…、8.4的最佳预测——模糊决策,并与常规方法做了比较。
A large numbers of intensity isoseismal maps for earthquakes occurred In Xinjiang have been analysed to obtain acknowledge and experience.In this paper,fuzzy information analysis theory has been used to assess the earthquake damage area in the region.Using the information assignment concept to set up directly two-dimention experience relation between damage area and the magnitudes,the best prediction-fuzzy decision is obtained for mi=4.9,5,4,5.9,……,8.4 for which I=IV°,V°,VI°,……IX°by means of calculation:and information concentration.
