‘陆地’ (lù dì) literally combines ‘陆’ (lù), meaning ‘land’ or ‘mainland’, and ‘地’ (dì), meaning ‘earth’ or ‘ground’. Together, they refer to solid, non-aquatic terrain — the dry surface of the Earth, as opposed to oceans, seas, or islands. It is a neutral, formal noun commonly used in geography, science, news, and everyday speech when distinguishing land from water.

The term emphasizes physical territory rather than political boundaries; for example, it’s used when discussing continental landmasses, wildlife habitats, or transportation infrastructure. Unlike ‘土地’ (tǔdì), which often implies soil, farmland, or ownership, ‘陆地’ focuses on geographical extent and natural surface area. It can also appear in compound terms like ‘陆地动物’ (land animals) or ‘大陆’ (continent/mainland), though ‘大陆’ carries stronger geopolitical connotations.
