Multi-Criteria Evaluation (MCE)is one of applications of multiple criteria decision making(MCDM). GIS is an information system that is designed to work with data referenced by spatial or geographic coordinates. GIS combined with MCE can achieve measurable evaluation of drought risk. Technologies of evaluating agriculture meteorological drought risk with GIS-MCE are introduced, Taking precipitation anomaly as main drought evaluation index, the paper calculated the spatial distribution of meteorological factors to the whole region by the interpolation method of IDW. In addition, use multiple regression analysis method to study the correlation of meteorological factors, geography factors and social economic factors. The study fully reflects the important role of population density and regional economic development for drought division, making the drought spatial distribution model more accurate and comprehensive. Ultimately, In considering each factor effects, calculate the multi-factor comprehensive division map by GIS-MCE method, which including establishing evaluation criteria and weight by Delphi method, obtaining the spatial distribution of factors of the meteorological drought risk by diffusing spatial attribute value and implementing evaluation by spatial overlay calculation. The results indicated that technology of GIS-MCE can combine multiple source information associating with agriculture meteorological drought risk and achieve measurable result.
