Abstract: Swamp as an unique natural complex is one of the component parts of geographical landscapes. Conventionally only the swamp distribution and the ratio of their area are shown on the general geographic maps. The types of swamps have never been distinguished scientifically.Contents of swamps representation on general geographic maps are discussed, including cartographic classification of swamps and method of expression area method expressed with symbols. According to the result of research work of our institute in recent years and our experience in compilating practice,we use the sheet of the north-eastern part of China at the scale of 1: 1,500,000 as an example. Preliminary experience are introduced, including (1) analysis and utilization of cartographic informations) (2) field observation and mapping, (3) cartographic generalization, (4) procedure of compilation. Finally, the authors point out that there are still some defects in the representation and compilating method for swamps on these sheets that need further study.
