摘　　要：通过分析1980年以来发生在新疆境内的地震，发现大多数Ms≥5．0地震发生在前兆异常密集区（专家系统高信度区和各类前兆异常叠合集中区）的边缘和外围邻区，而不是发生在通常认为的前兆空间分布密集区的中心及附近地区。为了缩小强震地点预报的尺度，必须考虑上述事实。用材料组合模式和板内复杂地震断裂带模式可以探讨其机理。According to the analysis for the earthquake examples in Xinjiang from 1980 to now, it is found that the majority of earthquakes with Ms≥5. 0 occurred in the edge and outlying areas of the densely anomalous areas (overlapping areas of expert system high-creditability areas and the dense areas of all kinds of precursor anomalies), not in its center and neighbouring area of the center. In order to reduce the prediction range of strong earthquake sites, it's necessary to consider the fact above mentioned. In addition, the mechanism of strong earthquake occurrance is discussed by using material combination pattern and complex intraplate fault zone pattern of earthquakes.
