We have calculated the climate risk index and the ecological index in the years 2000 to 2010 in the Medium temperature desert steppe of Inner Mongolia. Based on the data we can determined the regional land vulnerability factor and get the ecological risk index and delimit its level by calculating. And we also analyzed the special differentiation law of climate risk and ecological risk. And finally we draw the conclusion. The conclusion is: Within the study area, the spatial distribution trend of the ecological risk level is almost the same with the trend of climate risk during the years 2000-2010. The highest ecological risk areas are along the northern and western part of City Erlian. The level of the ecological risk gradually becomes smaller in the eastern and southern part of the two regions. The distribution of the ecological risk index influenced by human beings there is rather broken.
