英文释义
名词 n.
-
A division in altitude (or latitude) above which trees tend not to grow on mountains.
— Snowsheds and snow fences protect the line on either side of Semskfjell, but the country soon begins to lose some of its bleakness, and the tree line is regained at Lønsdal (1,680 ft. above sea-level), where the line is high on a hillside, commanding widespread views of the mountains.
