The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP. For NRPPs, this entity may, for example, correspond to a watercourse, a geologically unstable area.风险源（risk origin）指一类现实世界实体，其存在本身即构成潜在风险。该风险源可通过名称进行表征；在部分场景中，还可借助定位该致险实体的地理对象来明确其具体信息。实体的空间位置与危险现象的相关认知，可用于界定风险池（risk pools）——即支撑RPP的风险暴露区域。针对NRPPs，此类实体例如可对应为水道、地质不稳定区域。
