Abstract:

Using EOS/MODIS data obtained from 15 to 18 April in 2003 in Diebu fatal forest fire,the drought before fire,the fire region among fire and the fire area after fire are analyzed roundly. The result shows that EOS/MODIS telemetry can improve ability to inspect forest fire and drought, and sustain forest fireproofing technically. The brightness temperature in day and night and NDVI obtained from 31 channel of EOS/MODIS can reflect the soil humidity and the vegetation, and can be used to forecast forest fire and estimate fire danger. The drought is reflected by EOS/MODIS telemetry in the first and second ten days of April 2003, and advantage Diebu fatal forest fire. EOS/MODIS can inspect forest fire continuously, and offer the fire region, fire area and temperature and so on. The fire area can be estimated by using the change of vegetation index in the fire.

Key words: EOS telemetry, fatal forest fire
