Extreme precipitation disaster risk assessment data set (2019)

Based on 100m risk assessment data set and 100m vulnerability assessment data set, this data set respectively gives different weights to the risk and vulnerability (the risk weight is 0.8, and the vulnerability weight is 0.2), and 34 key node 100m risk assessment data sets are obtained by adding. One belt, one road area, is evaluated for flood risk in extreme areas. The data provide basis for local government departments to make decisions, and early warning before flood disasters, so that we can gain valuable time to take measures to prevent and reduce disasters, and to reduce the loss of lives and property of people caused by floods.

本数据集基于100米级（100m）风险评估数据集与100米级（100m）脆弱性评估数据集构建，分别对风险与脆弱性赋予差异化权重（风险权重为0.8，脆弱性权重为0.2），经加权融合后得到34个关键节点的100米级（100m）风险评估数据集。针对"一带一路"沿线区域的极端场景开展洪涝风险评估，本数据集可为地方政府部门制定决策、实施洪涝灾害前置预警提供依据，助力争取宝贵时间以采取灾害防控与减灾措施，进而降低洪涝灾害造成的人民生命财产损失。
