One major problem is that degraded soils become compacted and so absorb less water, which then tends to run off the surface, taking topsoil with it.
一个主要的问题是，退化的土壤变得密实，造成吸水量减少，从而导致水从地表流失并将表土带走。
As more droplets are attracted, they spread out and eventually join together and run off the surface-as they do on a pane of glass.
越来越多的水滴聚集，滚到涂层上，就像在玻璃板上一样。
