【Abstract】 Mire Map of China is first mire map of the whole country, in a sense. The map with attached maps vividly and systematically summarizes reflects research results of former Changchun Institute of Geography, Chinese Academy of Sciences, and other relative units of China in the past 40 years. It shows types, features, formation and distribution law of mire and paludfied land in China and its main typical areas. The map puts stress on showing the classification system and regionalizaton system with the new view point suitable to the mire features of China, in which mires were divided into four classes: type (1st class), subtype (2nd class), form (3rd class), group (4th class). In the map paludified lands as a parahel type were showed, and also were divided four classes. The main map (1∶ 4 000 000) shows 1st -3 rd class types of mire and paludifiedl and. Mire maps of the typical areas (1∶ 200 000- 1∶ 1 500 000) as its insert maps (2 sheets) or attached maps (4 sheets) mainly showed 4th class type. Another insert map is Mire Regionalization Map of China (1∶ 25 000 000), it reflects 8 mire regions and 40 mire subregions in China. The comprehensive type map was adopted. The representation method is area method and symbol method, the former referring to map units larger or equal to 1 square millimeter, the latter to the smaller than 1 square millimeter. The integration of comprehensive analysis and use of the mapping materials, field examination and contracted drawing were used. The transitional maps were first compiled and then the manuscript maps.更多还原
