Volume_at_risk_individual_disturbances

Individual proportions (%) of volume at risk associated with the four disturbances for each HDR zone and each observed and predicted periods, before overlaps between drought and insect outbreaks have been considered. HDR zones ID are provided in the shapefile data.在尚未考虑干旱与虫害暴发的重叠影响前，各HDR区域（HDR zone）及各观测、预测时段内，与四类扰动相关的受风险体积分项占比（百分比）。HDR区域的标识符已在形状文件（shapefile）数据中提供。
