Histosols and landscape CN
A Hemi-Orthic Histosols and landscape. These soils mainly distribute in Sanjiang Plain, Songhuajiang-liaohe Plain, and western Jilin Plain, as well as in gentle and broad valleys in low mountain and hilly areas in Wanda Mountain, Zhangguangcai Mountain, foothill of Changbaishan Mountain, and north-eastern Liaoning Province. Owing to poor drainage and seasonal waterlogging on ground surface, profiles of this soil are mostly saturated. Vegetation in areas concerned is composed of Cyperus rotundus, Deyeuxia langsdorffii, and Carex spp. In recent years, due to the building of water conservancy projects and increased developing of paddy field, the coverage of rice culture has been increasing year by year. Hemi-Orthic Histosols are mostly characterized by dominating hemic material in their surface tier, thicker profile and fragile weakly developed prismatic-blocky structure. (Photos and notes courtesy of China Soils Museum, Guangdong Institute of World Soil Resources; with revision.)
In Chinese Soil Taxonomy, Histosols have high amounts of organic matter accumulation under conditions of wetness and low temperature. In Soil Taxonomy these soils are mostly Histosols.
