干旱

• 拼音: gān hàn
• 汉字拆解: 干 = 一 + 十 (dry, bare); 旱 = 日 + 干 (drought — sun above dry ground)

含义

Drought; dry and parched. A prolonged period of abnormally low rainfall resulting in water shortage and agricultural damage.

Used as both a noun (干旱来袭 — drought strikes) and an adjective (土地干旱 — arid land). Common in agriculture, meteorology, environmental science, and news reporting. Often paired with 缺水 (water shortage) and 减产 (crop failure). Distinct from 干燥, which simply describes a low-moisture state without implying disaster.

例句

1. 持续数月的严重干旱导致当地大片农作物减产，粮食供应出现明显的结构性缺口。
2. 科学家警告，全球气候变化将使部分地区的干旱频率和强度显著增加，威胁粮食安全。
3. 干旱的气候条件迫使当地农民不得不调整种植结构，逐步转向耗水量更低的经济作物。
