An application of NOAA/AVHRR data to the monitoring of conditions of drought and waterlogging related to agricultural production is described in this paper. The CH4.2.1 colour composed images as a basis for qualitative interpretation, and the vegetation index (NDVI) which is formed from the CH1, CH2 reflectivity data as a quantitative standard to monitor the summer waterlogging in 1987, summer drought in 1988 and drought for winter wheat in 1989 were used.The research proved that in a desaster district the NOAA/ AVERR data can be used to determine the extent of desaster, to classify the condition of desaster, to calculate the suffering area and to monitor the tendency of desaster development,and good results call be obtained.
