Making the situation worse is the fact that the topsoil is only about 25 cm deep. (In Taiwan, topsoil is typically from 50 cm to one meter deep.) This means that many deep-rooted plants cannot be grown because they are too easily blown over by the wind.
況且表土淺薄，不過二十五公分左右（台灣的表土一般可由五十公分到一公尺），使得許多深根性的作物，風一吹就倒下去，根本種不起來。
