Abstract: Based on the data of the distribution of white-naped crane (Grus vipio) breeding areas in Northeast China and the environmental factors including temperature and precipitation, potential distribution of white-naped crane breeding areas in Northeast China was predicted using the Maximum Entropy Model (Maxent). On such a basis coupled with three atmospheric circulation models and two climatic scenarios, impacts of climate change on the distribution of white-naped crane breeding areas were predicted, too. Results show that in the future scenarios of changed climate，the distribution of white-naped crane breeding areas would decrease in area and move towards north and west. The change in Scenario A2 was greater than that in Scenario B2, and the trend of moving towards north and west more obvious.It can be concluded that climate change has a distinct impact on the distribution of White-naped Crane breeding areas in Northeast China.
