We used the finite fault-rupture model of the M_W6.3 Jinghe earthquake to estimate the displacement field, the stress field, the static coulomb stress changes on the main faults around the seismic area and study the static stress triggering effect on aftershocks. The result indicates that:(1)Generated by the Jinghe earthquake, the maximum surface uprising is about 6.6cm, while the maximum surface subsidence is about 1.8cm. Study shows that the horizontal displacement in south and north gathers in the epicenter, while in east and west the displacement direction is toward each side separately. (2)The stress field on the horizontal plane indicates that the substance located on the south and north sides of the epicenter is in extension, yet on the east and west sides it is extruded in the east-west direction by the surplus substance in the epicenter being discharged to east and west sides. (3)The Jinghe earthquake has a stress triggering influence on the middle part of the Kusongmuxieke piedmont fault near 20km from the epicenter and the west part of the Four trees-Gurt fault near 50km from the epicenter. The coulomb static stress changes of these two faults have increased over 0.01MPa, so that these two have high seismic risk. (4)About 85.5% of the aftershocks distributed in the depth of 8km to 12km are located in the Coulomb stress loading zone, so that they are triggered by this earthquake. Nearly 87% of the aftershocks in the depth of 4km to 8km are triggered by this earthquake.
