CLASSIFICATION OF CRYOSOLS:SIGNIFICANCE, ACHIEVEMENTS AND CHALLENGES

Institute of Soil Science, Chinese Academy of Sciences, Nanjing 210008, P. R. China

摘要: International concerns about the effects of global change on permafrost-affected soils and responses of permafrost terrestrial landscapes to such change have been increasing in the last two decades. To achieve a variety of goals including the determining of soil carbon stocks and dynamics in the Northern Hemisphere, the understanding of soil degradation and the best ways to protect the fragile ecosystems in permafrost environment, further study development on Cryosol classification is being in great demand. In this paper the existing Cryosol classifications contained in three representative soil taxonomies are introduced, and the problems in the practical application of the defining criteria used for category differentiation in these taxonomic systems are discussed. Meanwhile, the resumption and reconstruction of Chinese Cryosol classification within a taxonomic frame is proposed. In dealing with Cryosol classification the advantages that Chinese pedologists have and the challenges that they have to face are analyzed. Finally, several suggestions on the study development of the further taxonomic frame of Cryosol classification are put forward.
