| Abstract: | Based on the worldwide definitions of agricultural drought, comparative analysis of different indices suitable for risk assessment of agricultural drought disasters was performed. The risk assessment methods for the agricultural drought disasters were summarized, and the relevant applications were introduced. The theories, methods and advances of forecast warning for the agricultural drought were reviewed. The trends of risk assessment and forecast warning for the agricultural drought disasters were prospec... |
