摘　　要：介绍了新疆呼图壁21号泉的水文地球化学环境,分析了该泉动水位变化的原因;总结了其震兆特征的变化规律,并对该泉的映震效能进行了评价。最后对其映震机理和映震性能较好的原因进行了探讨和分析。Firstly, the hydro-geochemistry environment in No.21 spring,Hutubi, Xinjiang is introduced and the reasons of change of moving-water level are analyzed. Next, the change principle of its earthquake precursor is summarized, and the reflecting earthquake ability is evaluated. At last, the reflecting earthquake mechanism and why the ability is well are discussed.
