Fibri-Orthic Histosols distribute widely, though relatively concentrated in lake depressions, lower river terraces, oxbow loops in Sanjiang Plain, Songhuajiang-Nenjiang Plain, and on North-western Sichuan Plateau. Besides, they are found in valleys of branches of the upper stream of Yellow River. Owing to ground waterlogging in most seasons of the year, profiles of this soil are saturated all the year around. Vegetation in areas concerned is mostly composed of Carex spp. Besides, Deyeuxia langsdorffii, Phragmites communis, Phragmites comunis, Equisetumhyemale, Cyperus rotundus, Bolboschoenus spp.,and Artemisia spp. are also found there. All those plants grow closely as individual thick bushes called “Tatoudun”( a pagoda-top like grass hummock). With a thick profile and large amount of fabric organic material, the type of soil can be used to grow rice and wheat after artificial drainage.
