摘要：Soil map that shows the geographical distribution regularity of different soil types and the soil resources diversity is an important type of categorical maps. And soil map is applied in various professional studies such as vegetation studies, land use and environmental studies, and resources management. Therefore, soil map generalization not only follows the generic principles of cartographic generalization, but also is supervised by the professional principles of soil distribution. This paper explores the professional principles of soil distribution according to the regularity of soil distribution, the characteristics, representation and application of soil maps as specific constraints to soil map generalization. The specific constraints are indispensable for the comprehensive generalization of soil map. Then associating with the research of Peter and Weibel (1999) on generic constraints to generalization of categorical data, the specific constrains and generic constraints are integrated and applied in the different phrases of the generalization process to investigate the functionalities. The last component of this paper discusses two special issues of soil map generalization to demonstrate the importance and application of specific constraints to soil map generalization
