This rapid zone of transition is called the upper timberline or tree line.
这种快速的过渡地带被称为“上树带线”或“林木线”。

There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline.
对于为什么树线以上的树木会突然停止生长，至今还没有一个公认的解释。
In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.
在许多半干旱的地区中，同样存在树带界限的下限区域；在这片区域之内，由于缺乏水分，森林下沿区域的植被通常会逐渐变成干草原或沙漠。
