Abstract
Drought and frost are two main natural disasters to winter wheat in China northern plain. Based on MODIS data in the last ten years, sensitive analysis of vegetation indices to these two disasters is presented in this paper. The result showed that EVI, NDIIb6 and NDIIb7 are suite for frost damage assessment. Although the winter wheat suffered serious drought in this region, the stress characteristics of winter wheat responded by both greenness change indices and water content change indices are not obvious.
