Abstract: Land series mapping is a new field in land research and geographical mapping This paper discusses some basic problems in the mapping work of the loess plateau in Northern Shanxi,1. The objects and features of the series of land type maps.This land unit in different levels can be taken as the cartographical objects of the maps in different scale in Northern Shanxi,as follows: 1:1000000 scale may be regarded as compound land type 1:500000 scale as complicated land type, 1:100000 scale as simple land type, 1:50000 scale as land unit, and 1:10000 scale as land element.There are totally six kinds in mapping of a series of land type, each scale has a special feature of its own.2. The procedure and methods of compiling of the series of land type maps.The procedure of the mapping consists of four stages; namely, the preparatory stage, the stage of comliling the draft maps, the stage of co-ordinating the series of maps, and the final completing stage,The compiling of land type series follows the general criterion of land type maps, and in addition, in compiling large, middle, and small scaled land type maps, each scale has special methods of its own. But any map of land type should be made by combining the conventional methods with new technical methods.3. The feature, the theoretical basis and the principles of the series of land type maps.There are chiefly four features of the series of laud type maps, namly. independent character, connection, subordinate and entirety,The theoretical basis of the series mapping is that the land have different levels in a hierarchy and the close connection, This land unit in different levels can be taken as the cartogrphical objects of the maps in different scale.Three basic principles can be followed in the mapping. 1.Taking the different maps into a series. 2.Keeping the viewpoint as one in the series mapp ing, 3. Consider ing the cartographical generalization.
