意味

源流／発生源（原因の元）

More concrete and spatial than 源泉, 源头 often refers to the physical starting point of a waterway or the traceable origin of a problem or event. 追溯源头 (trace back to the source), 从源头治理 (govern from the root cause), 找到问题的源头 (find the root of the problem), and 文化源头 (cultural origin) are common in policy, analytical, and investigative contexts. Emphasises traceability and causal priority.
