中国县级尺度洪涝灾害设防能力评估数据集（2020）

根据《防洪标准(GB 50201 -2014)》评估中国县级防洪水平（年遇型）。参考最新发布的《防洪标准GB 50201-2014》，构建了基于政策的中国防洪水平数据集，并进行了数据验证，数据集相对准确。在171个随机样本县中，数据集与设计文本的匹配率达到53.2%。数据集将开放访问，鼓励相关用户使用和改进。该数据可以为洪涝灾害风险评估和管理提供数据支撑。如果需要详细的数据信息，请阅读并参考以下已发表的论文。Wang D, Scussolini P, Du S. (2021). Assessing Chinese flood protection and its social divergence. Natural Hazards and Earth System Sciences 21 (2):743-755. https://doi.org/10.5194/nhess-21-743-2021.

This dataset assesses the county-level flood control levels (annual return period-based) of China in accordance with the Standard for Flood Control (GB 50201-2014). Developed based on the newly released Standard for Flood Control GB 50201-2014, this policy-based dataset of Chinese flood control levels has undergone data validation and is relatively accurate. Among 171 randomly selected sample counties, the matching rate between this dataset and official design documents reaches 53.2%. The dataset will be openly accessible, and relevant users are encouraged to utilize and improve it. This dataset can provide data support for flood disaster risk assessment and management.
