摘要：
Based on the standard formulation of natural disaster risk, the composite Maize Drought Disaster Risk Index (MDDRI) at different growth stages of maize combined the hazard of agricultural drought, the exposure of the maize the vulnerability of the maize, and management ability for drought disasters were developed by using Analytic Hierarchy Process (AHP), Weighted Comprehensive Method (WCM) and Optimal Partition Method (OPM), supported by GIS and technology of natural disaster risk assessment. The MDDRI can be used to compare different relative contributions such as natural and socioeconomic factors to drought disaster risk, and the relative risk of drought disaster to maize production at different stages of maize growth.
