摘　　要：整理了首都留１９８９年以来的水化群体资料，考虑到水化观测台站分布的非均匀性，计 算其空间非均匀性指标Ｃｖ值。结果表明，水化前兆群体非均匀性指标Ｃｖ值异常与首都圈６级 以上强震的发生有较好的相关关系，说明Ｃｖ值的变化与地震孕育、发生过程存在着密切的联 系，据此可以对未来的地震趋势作出一定预报。Arranging the capital region 's hydrochemistry data since 1989, and considering the non- uniformity character of water chemistry observations station distribution , the space non-uniformity character index Cv value has been computed. The results show that the relation between variety of hydro- chemisty anomalies of non-uniformity index Cv Value and the Ms≥3 6.0 earthquakes occurred in the capital region is better. It is suggested that the variety of Cv value have a closely connection with the process of originate and occur, hereby, the trend prediction of coming event can be made.
