Abstract

This article constructs an integrated methodology for cotton vulnerability assessment by incorporating the Historical Yield Loss Records, and conducting Field Investigation and Ground Experiments (HiReFiGe). By taking hail intensity and the bolls loss as key indices, this research got four vulnerability curves of cotton at different growth stages of seedling, bud, boll, and boll opening stages respectively. Results indicate that the vulnerability of cotton to hail varies at different growing stages, which are highest in stage of seedling and the bell, followed by the bud stage and the boll opening stage. Therefore, the seedling and boll stages are the key period for cotton hail disaster mitigation and risk governance. At national scale, with the increase of loss rates, the occurrence probability reduces gradually. The highest probability areas are the eastern part of Shanxi, Aksu of Xinjiang Autonomous region, indicating that these regions are highest hail disaster risk area for cotton, where should be paid more attention to cotton hail hazard prevention. This research presents an integrated approach to evaluate the cotton vulnerability to hail, which can be a scientific reference for cotton insurers and the local governmental decision-makers.
