喜马拉雅山区1：100万脆弱房屋比分布数据（2016）

本数据为喜马拉雅山区1：100万脆弱房屋比分布数据，对喜马拉雅山区每个村进行入户调查其房屋的构造，将入户调查房屋分为1类钢筋混凝土结构房屋、2类混合结构房屋、3类砖木结构房屋、4类其他结构房屋4种类型，经过分析将防御山洪能力较弱的3类砖木房屋和4类其他结构房屋确定为脆弱房屋，将每个村房屋总数和脆弱房屋总数相比较，得到喜马拉雅山区内各个村脆弱房屋总数占房屋总数比例，最终形成喜马拉雅山区脆弱房屋比分布数据。This dataset is a 1:1,000,000-scale distribution dataset of the proportion of vulnerable houses in the Himalayan region. Household surveys were conducted to investigate the housing structures of all villages in the Himalayan region, and the surveyed houses were classified into four categories: Type 1 reinforced concrete structures, Type 2 composite structures, Type 3 brick-wood structures, and Type 4 other structures. Subsequent analysis identified Type 3 brick-wood structures and Type 4 other structures as vulnerable houses due to their poor flood defense capabilities. By comparing the total number of houses and the total number of vulnerable houses in each village, the proportion of vulnerable houses to the total housing stock for every village in the Himalayan region was calculated, and the final distribution dataset of the proportion of vulnerable houses in the Himalayan region was thus formed.
