摘　　要：首先简要介绍了模糊分维的概念与确定方法.然后以郯-庐大断裂南段(北纬30°-40°)的地震活动时间,空间分布为基础,研究了这一区域受到地震影响的模糊时间,空间分维特征,并用模糊分维划分受到地震活动的高潮期和探索强震前的中长期测展学前兆异常指标.结果表明未来10年是呈上升趋势的时期,为受到地震活动影响的高潮期.First,this paper studies the fractal dimension features of time and space of this region affected by the earthquake based on the seismic activity period and space distribution of Tan-Lu Fault and southern（ latitude 30°N-40°N）,and then it divides the climax period influenced by earthquake activity with fuzzy fractal dimension,and explores long-medium-term precursory anomaly index before strong earthquakes. The result shows that the node of Tan-lu Fault southern section is fuzzy fractal dimension D,and also shows that it presents an upward trend period,and is thought to be the climax period influenced by earthquake activities in next ten years.
