‘田坝’ (tián bà) refers to a flat, open area of land that has been cleared and cultivated for agriculture—especially rice paddies—in mountainous or hilly regions of southern and southwestern China. The character 田 means 'field' or 'farmland', while 坝 originally denotes a natural or artificial embankment or flat terrace formed by sediment deposition or human construction; together, they evoke a fertile, level expanse amid otherwise rugged terrain.

This term is commonly used in geographical descriptions, rural development reports, and local place names—particularly in Yunnan, Guizhou, and Sichuan provinces—where such plains are vital for farming and settlement. Unlike generic terms like 田野 (tiányě, 'countryside') or 稻田 (dàotián, 'rice field'), 田坝 emphasizes the topographical feature: a broad, low-lying, human-modified plain suitable for intensive cultivation. It carries a regional, somewhat literary or descriptive nuance rather than everyday conversational use.
