摘　　要：利用１９７０年以来江苏及邻区１０次震群资料，对其单项及综合指标作了计算和研究，根据《地震学分析预报方法程式指南》判断其前兆性。另外，对前兆震群与未来强震距离、间隔作了统计，并对其预报效能作了评估。The single term and comprehensive indexes are calculated and studied for 10 swarm data in Jiangsu and adjacent area since 1970. Their precursory property is discriminited from 《Guide to Earthquake Prediction Methods》. Besides, the relation of precursory swarm to the distance from the future strong earthquake is statistically studied, and its prediction efficiency is assessed.
