Abstract: Gobi is one of the main landscape types in the arid regions in northwest China. There is an area of about 661 thousand km2 in China, accounting for 6.9% of the total territory, and meanwhile, there are abundant natural resources, such as land resources, biology resources, solar energy resources, wind energy resources, and mineral resources in the gobi region. However, bad natural conditions and sparse population in this region lead to few field investigations, and thus few research documents related to the gobi can be obtained. Establishing a series of unified gobi classification standards and cataloging system are not only the theory basis for conducting further gobi studies, but also the precondition for developing the abundant natural resources in the gobi region reasonably. So far, there are few research documents related to the gobi status, gobi distribution and gobi type classification, and the research documents on the gobi cataloging are even more scarce. In combination with the existing study on the gobi classification system, the result analysis of science exploration for the gobi and the discussion results of expert panels, the gobi classification system with three levels is put forward to promote the standardization of gobi research according to the cause of gobi formation, the material composition of earth's surface and the vegetation characteristics. At the same time, the relevant characteristics of each gobi type at all levels are described in detail. Moreover, some ideas on the gobi cataloging are also presented so as to collect, collate and record the main characteristic data and the related information for each gobi type systematically. It is inferred that these results can promote the standardization of gobi research.

Key words: gobi, gobi inventory, gobi classification system
