Abstract  

Gobi is one of the main landscape types in the arid regions in the northwest parts of China. At present, it is difficult to do fieldwork due to the bad natural condition and sparse population in gobi region, which led to the scarcity in research documents on the gobi. According to current few research documents on the gobi, cross classification existed in the gobi classification systems. So, it was difficult to classify the gobi. Moreover, the current gobi classification systems did not take the whole situation into account. In order to promote the standardization of gobi research, the concept of gobi was definitely presented, then the connotation of gobi was described and explained from the climate, driving force, topography, land surface material composition, vegetation, water and soil. Based on the gobi classification indicators, a set of gobi classification system was established in this paper from the angles of the reason of gobi formation, the composition of land surface materials and the vegetation coverage, which fully considered the aim of ecological protection and utilization in gobi regions and was easy to be used for conducting the remote sensing image recognition. In addition, the expression characteristics of each type of gobi at each level in the remote sensing image and how to recognize the gobi type by remote sensing image, were described in this paper.

Key words:  gobi      definition      classification system      remote sensing
