| 摘 要： | 采用了模糊集理论与分形理论相结合的模糊分维方法，计算了河南范县豫01井水位动态的模糊分维值，并分析了与1981年河北宁晋Ms 5.8、1983年山东菏泽Ms 5.9、1985年河北任县Ms 5.0地震的关系。结果显示，模糊分维值在这3次地震前都明显地出现了小于0．75的降维低值异常特征。且震级越大，震中距越小，异常时间越长；反之则相反。

| Abstract: | Adopting the fuzzy fractal method which combines fuzzy set theory and fractal theory, the fuzzy fractal values of dynamic water -level in yu -01 well, Fanxian county, Henan Province, are calculated, and the relationship between the fuzzy fractal value and three earthquakes (Ningjin MS5.8 in 1981, Heze MS5.9 in 1983, and Renxian MS5.0 in 1985)is analysed. The result shows an abnormal characteristic that the fuzzy fractal value fell down to less than 0.75 apparently before three earthquakes, and the larger the degree of earthquake is and the smaller the epicentral distance is, the longer the time of abnormal characteristic last. |
