毛乌素沙地,中国四大沙地之一。一千多年之前这里曾草滩广大,水草丰美,风光宜人,是一片很好的牧场。此后由于不合理开垦、气候变迁、战乱等原因,这片土地像一块具有传染性的皮肤,沙化面积不断向四周扩散。不过,这里如今大部分地方再次被绿色覆盖。
Mu Us Desert, one of four China’s sandlands. More than a thousand years ago, it was a vast grassland, with clear water and beautiful scenery. Due to over-reclamation, climate change, war and other reasons, this land is like a contagious skin, deserted area continuously spread around. However, most of the area here are now covered in green again.
