摘      要：Climate change can lead to and intensify drought *** the vulnerability of disaster-affected elements is significant for understanding the mechanisms that transform drought intensity into eventual *** study proposed a growth-stage-based drought vulnerability index(GDVI)of soybean using meteorological,groundwater,land use,and field experiment data and crop growth model *** CROPGRO-Soybean model was used to simulate crop growth and water *** growth stages were considered since the sensitivity of soybean to drought is strictly related to the growth *** GDVI was applied to the Huaibei Plain,Anhui Province,China,with the goal of quantifying the spatiotemporal characteristics of soybean drought vulnerability in typical years and growth *** results show that:(1)The sensitivity of leaf-related parameters exceeded that of other parameters during the vegetative growth stage,whereas the top weight and grain yield showed a higher sensitivity in the reproductive growth stage;(2)A semi-logarithmic law can describe the relationship between the drought sensitivity indicators and the GDVI during the four growth *** pod-filling phase is the most vulnerable stage for water deficit and with the highest loss upper limit(over 70%);(3)The 2001 and 2002 seasons were the driest time during *** and Huainan Cities were more vulnerable to drought than other regions on the Huaibei Plain in 2001,while Huaibei and Suzhou Cities were the most susceptible areas in *** results could provide effective decision support for the categorization of areas vulnerable to droughts.
