摘　　要：采用非均匀度方法,分别提取滇西北、滇中北、滇西南、滇东南和滇东北地区水氡观测资料的地震前兆群体异常。结果表明,该方法能满足水氡观测点所在地区成组中强地震的中、短临预报要求;且该方法能自动识别异常,排除人为主观影响,便于在其他震区进行预报效能检验。Using inhomogeneous degree of swarm deformation anomaly method, the earthquake pre- cursory group anomalies of water radon observations from northwest Yunnan,north Central Yunnan,southwestern Yunnan, southeastern Yunnan and northeast Yunnan are extracted. The results show that the method can meet in short-term prediction of strong earthquakes in the water radon observation point where the region into requirements, and the method can automatically identify anomalies, exclude subjective effects, easy to predict the performance test in other quake zone.
