研究了我国西部走滑型地震的地表破裂长度Ｌ和位移量Ｄ与震级Ｍ＿ｓ和复发时间间隔Ｔ之间的定量关系。结果表明：震级Ｍ＿ｓ和复发间隔Ｔ不仅与Ｌ值有关，还同时与Ｄ值相关；乘积ＬＤ值可用来估算震级Ｍ＿ｓ，比值Ｄ／Ｌ与复发间隔Ｔ密切相关；对于Ｍ＿ｓ或ＬＤ值给定的地震，Ｄ／Ｌ值大（即Ｌ值小或Ｄ值大）的地震，有较长的复发间隔；当破裂长度Ｌ一定时，有较长复发间隔的地震，Ｍ＿ｓ或ＬＤ值较大；当位移量Ｄ相同时，Ｍ＿ｓ或ＬＤ值较大地震的复发间隔较短。
The quantitative relationship between the rupture length L, the displacement D and the magnitude M_s and the recurrence interval T of the western strike-slip earthquake in China was studied. The results show that the magnitude M_s and the recurrence interval T are not only related to the L value but also related to the D value at the same time. The product LD value can be used to estimate the magnitude M_s and the ratio D / L is closely related to the recurrence interval T. For the given M_s or LD value Earthquakes, earthquakes with large D / L values (ie small values of L or large values of D) have longer recurrence intervals; those with longer recurrence intervals have larger M_s or LD values when the rupture length L is constant; When the displacements D are the same, M_s or LD value is larger, and the recurrence interval of earthquakes is shorter.
