Abstract: In order to effectively monitor drought information in Hubei province,a drought monitor and analysis system based on WebGIS was exploited.In the system,meteorological factors of no-station area were refined simulated by GIS techniques.Precipitation Anomaly Percentage(Pa),Relative Moisture index(Mi),Standard Precipitation Index(SPI),Composite Index(Ci) and Palmer Drought Severity Index(PDSI) were applied to reflect comprehensively the true drought circumstances in Hubei province.It was confirmed that the drought monitoring system could correctly reflect drought circumstances of Hubei province.With high running speed and accurate diagnosis of drought circumstances,it will play an important role in drought monitoring.

Key words: WebGIS, Drought monitoring, Grid, Hubei province
