- 应用b值空间扫描方法，分析福建地区政和海丰断裂带上发生的ML≥4.5中强地震前b值空间扫描图像。分析结果表明：在此断裂带上发生中强地震前,均存在b值空间扫描异常现象，且震中皆在异常区域内。b值空间扫描方法，对政和海丰断裂带ML≥4.5中强地震发生的时间、地点映震效果明显，对该断裂带上发生的中强地震进行中短期预测有一定效果。
In this paper, bvalued space scanning method is used to analyze the magnitude bvalue space scanning images occurred before ML≥4.5 midstrong earthquake in the governed fault of ZhengheHaifeng in Fujian area. Analysis results show that the bvalued space scanning anomalies are occurred before midstrong earthquakes in the fault, and the earthquake occurred in anomaly area. b value spatial scanning methods for ML≥4.5 strong earthquakes in Fujian area is significantly effective to reflect earthquake in the time and place and has certain effect on shortterm prediction of strong earthquakes in the fault.
