    This study assessed the impacts of climate change in IMP by investigating vegetation responses droughtin multiple timescales. Methods used included the Normalized Difference Vegetation Index (NDVI) andStandardized Precipitation Evapotranspiration Index (SPEI), by annual maximum Pearson correlation(Rmax) and the corresponding month (Rmonth) of drought. Results showed that: (1) It is necessary tozone IMP when analyzing the vegetation responses to drought. (2) Rmax is significantly positive cor-relation in IMP, indicating that vegetation was largely in fl uenced by drought; the most seriously affectedareas are in the north-eastern part of typical steppe, south-western parts of steppe desert and southernpart of desert steppe, while light seriously are distributed in the south-eastern of typical steppe andforest steppe. (3) Vegetation in typical steppe, steppe desert and desert steppe are sensitive to shortertime-scales of droughts, while in the forest, forest steppe and sand desert, vegetation shows a closerelationship with the longer drought time-scales. (4) The effects of drought related climate extremes canalso contr ibute to Rmax and Rmo nth between SPEI and NDVI. Vegetation in forest and sand desert areas,have lower sensitivity to drought under the effect of climate extremes. Adaptation measures, such asbuilding drought resilience vegetation types, applying biochar and monitoring and forecasting drought,must be timely and effectively initiated, especially, in the typical steppe, steppe desert and desert steppein IMP since vegetation in these four areas is affected seriously, once drought occur. The results from thisstudy may provide useful infor mation about appropriate adaptation and mitigation strategies against theinverse effects of drought on vegetation, and even alleviate the losses caused by drought.
