Records on human-wildlife conflicts in Sanjiangyuan，Qumalai、Zhiduo and Nangqian Counties from 2015 to 2016 were analyzed to find the main causing species and to trace the rules in the time distribution、the geographic distribution and the damage patterns. As our results showed：（1）the main causing animals were Canis lupus（978 cases，64.13%）, Ursus arctos（117 cases，7.67%）, Uncia uncia（5 cases，0.33%）and Bos mutus（3 cases，0.20%）in order，leaving 422 cases（27.67%）without causing species information；（2）the time distribution of the conflicts was not very stable and the peak period differed in different years and regions；but totally，conflicts in January，February and December were fewer，and the peak period typically occurred during June to September；（3）as to the geographic distribution，the situation in Qumalai and Zhiduo was heavier，especially Qiuzhi and Maduo towns in Qumalai and Zhiqu，Duocai，Lixin and Zhahe in Zhiduo；the conflict hotspot was located in the juncture of Qumalai and Zhiduo Counties；the situation in Nangqian was relatively slighter；（4）the attack and injury to cattle（749 cases，79.94%）was the most common damage type，and conflicts with this damage type were much more than those causing damages to sheep（56 cases，5.98%）or horses（24 cases，2.56%），or house and furniture（108 cases，11.53%）. This study will provide reliable information for more effective actions to prevent and alleviate the human-wildlife conflicts in Sanjiangyuan.
