According to the annual precipitation and runoff data from 1966 to 2010, this paper analyned the inconsistency ofpreipitation and runoff in the Jinshajiang River Basin by using univariate Mann-Kendall test and mulivariate Mann-Kendall test.The results show that there s an increasing trend in the annual precipitation and runoff in the Jinshajiang River Basin，especiallyfrom the 1990.The precipitation in the middle reaches of the Jinshajiang River Basin shows an obvious upward tendency bypassing the MK significance test.The mutation point appears in the precipitation at the Panzhihua Station,which results in an obvious increase after 1997.There's not any other mutation points in both precipitation and runoff at the other stations.In addition,by passing the multivariate MK significance test， the joint variables of the Longie Station's precipitation and runoff show asignificant increase，while the other stations fail the test.
