本文通过可可西里－金沙江地震带震级频度关系的确定及其参数ｂ值与ａ值、ν值（地震年平均发生率）和Ｍｍａｘ（最大震级ａ／ｂ）之间的相关性分析，以说明地震危险性概率分析中的地震活动性参数ν值与ｂ值也应有某种相关性。当地震带未来一定时期内地震活动震级上限Ｍｕｚ和ｂ值被确定后，未来地震活动的ν值的取值范围似将受到一定的限制。如假设可可西里－金沙江地震带的Ｍｕｚ为８级，ｂ值为０．７３后，相应的ν值若取１３．９４３，可能偏小。
Based on the determination of the relationship between the magnitude of the Hoh Xil-Jinshajiang earthquake belt and the correlation between the b value and the a value, the ν value (the average annual incidence of earthquakes) and the Mmax (maximum magnitude a / b) There should also be some correlation between the seismic activity parameter ν and the b value in the probability analysis of seismic hazard. When Muz and b values of seismic magnitude upper limit within a certain period in the future earthquake zone are determined, the range of values of future seismic activity seems to be limited. Assuming that the Muz of the Kekexili-Jinshajiang seismic zone is level 8 and the b value is 0.73, the corresponding value of ν may be small if taken as 13.943.
