The method for drought monitoring by remote sensing and monitoring flow were introduced in the paper，which can transfer
NOAA／AVHRR data received from DVBS system to Erads software where geographical correction and image mosaic can be done，and
drought monitoring model can be made and Inn．Drought occul"l~d in four provinces ofNorthwest China in the last ten—day of July，
2006 was monitored by using this method and work flow．an d the results were in agreement with observations of soil moisture in this area．It shows if proper drought monitor model is chosen，the drought magnitude can be monitored by this method and work flow．
