地带 (dì dài) refers to a stretch or belt of land, often with a natural or geographical characteristic (e.g., 危险地带 dangerous zone, 森林地带 forest belt). It differs from 区域 (qū yù, general area) and 地段 (dì duàn, a specific section) by emphasizing a continuous strip or zone. 一带 (yī dài) is vaguer ('the area around'), while 地域 (dì yù) is broader and more formal.
