喜马拉雅山区山洪灾害分布数据（1840-2019）

本数据集包含喜马拉雅山区1：100万历史山洪灾害数据、喜马拉雅山区1：100万山洪防治区分布数据、喜马拉雅山区1：100万山洪分区分布数据、喜马拉雅山区1：100万重点防治区分布数据。各项数据均基于全国山洪灾害调查评价成果，得到研究区内历史山洪灾害发生时间、地点、灾害类型、成因、经度、纬度、数量、分布及因灾遇难人数信息，以及研究区内山洪分区分布、防治区范围分布和重点防治区分布数据，形成喜马拉雅山区历史山洪灾害分布数据集。

This dataset includes four 1:1,000,000-scale spatial datasets for the Himalayan region: 1:1,000,000-scale historical mountain flood disaster data, 1:1,000,000-scale distribution data of mountain flood prevention and control zones, 1:1,000,000-scale distribution data of mountain flood zoning, and 1:1,000,000-scale distribution data of key prevention and control zones. All data are derived from the national mountain flood disaster survey and assessment results, and contain information including the occurrence time, location, disaster type, cause, longitude, latitude, quantity, distribution, and number of casualties caused by the disasters of historical mountain flood events in the study area, as well as the mountain flood zoning distribution, scope distribution of prevention and control zones, and distribution of key prevention and control zones within the study area. This ultimately forms the Historical Mountain Flood Disaster Distribution Dataset for the Himalayan Region.
