简述了孟连7.3级地震中、短、临3个阶段的预报情况及主要依据。重点讨论了异常时空分布特征。结果表明，震前1a震中附近地震学空间扫描出现小震额度、调制比等8项异常，为云南省异常项目最多的地区；震前235d内震中附近出现中强震的时空密集活跃。定点前兆中期异常的主要特征是，某些项目具有异常持续时间长、异常幅度大，如龙陵水氛异常持续时间长达4．5a；永胜短水准、短基线异常幅度分别达20．9mm和22mm短临阶段主要表现为某些项目如水温、水氧、地倾斜、地磁等出现“巨变异常”，异常幅度比正常变化大几倍至几十倍；水汞、水氛异常开始时间外围早、震中附近晚。空间上，中短期异常主要集中在距震中200～400km，临震异常主要集中在震中距200～300km，其异常台项百分比分别达26％～29％和36．8％，其它范围仅0～19％。云南中、短、临异常台站和台项百分比分别为54．5％和38．4％。
The forecast situation and main basis of the three stages of Menglian MS 7.3 earthquake are briefly described. Focus on the abnormal spatial and temporal distribution characteristics. The results show that there are 8 anomalies such as small earthquake quota and modulation ratio in the seismological space near the epicenter before the epicenter, which is the most anomalous region in Yunnan Province. The main characteristics of the medium-term anomalies of sentinel precursors are that some projects have long anomalies and large anomalies, for example, the anomalous duration of Longling water anomaly lasts up to 4.5 years; the short-term and short-term baseline anomalies of Yongsheng reach 20.9mm And 22mm short and medium stages are mainly manifested in some projects such as water temperature, water oxygen, ground tilt, geomagnetic and other “catastrophic anomalies”, the magnitude of abnormalities several times larger than the normal change several times; water mercury, water anomaly start time outside Early, near the epicenter late. In space, the short-term and short-term anomalies mainly concentrated in the distance of 200-400 km from the epicenter. The anomalies of the main epicenters mainly concentrated in the epicentral distances of 200-300 km with the percentage of anomalous stations accounting for 26% -29% and 36.8%, respectively, 19%. Yunnan, short, temporary abnormal stations and Taiwan items were 54.5% and 38.4% respectively.
