BCAS Vol.24 No.4 2010 Vegetation Map and Vegetation Monographs of China GUO Ke Institute of Botany, CAS, Beijing 100093 Vegetation Map of China As the most significant component of an ecosystem, vegetation plays the most important role in maintaining biodiversity and providing the necessary resources for human beings. A vegetation map shows the major vegetation types of a region and their geographic distribution patterns. Ve g e t a t i o n M a p o f C h i n a i s m a d e u p o f t w o components: a vegetation type map and a vegetation regionalization map. The former shows the distribution of the main vegetation types in this country, and the latter displays the geographic differentiation of vegetation. Both of them represent the framework and patterns of geographic distribution of vegetation in China. At present, they have had several versions on different scales. The most up-to-date version so far is the Vegetation Map of the People’s Republic of China (1:1000,000) published in 2007. It includes the 60-page Vegetation Type Atlas (1:1000000) in folio and the Vegetation Regionalization Map (1:6,000,000) in standard-sized Larix gmelinii forest.

This Vegetation Type Atlas reflects the situation up to the 1990s, including the geographic distribution of 11 vegetation type groups, 55 vegetation types, 960 vegetation formations and sub-formations, and more than 2,000 dominant species of the plant communities and main crops. The Vegetation Regionalization Map illustrates geographic differentiation of vegetation in China. It divides the whole country into eight vegetation regions, 12 vegetation subregions, 25 vegetation zones, 116 vegetation districts, and 464 vegetation sub-districts (Editorial Committee of Vegetation Map of China, Chinese Academic of Sciences, 2007a). In addition, the maps have two explanation volumes. The Volume I first introduces the history of vegetation mapping, physiographic conditions of China and the flora, characteristics of vegetation distribution in China, principle of vegetation classification and the classification system; and then describes distribution area, habitat condition, species composition and structure of communities of the vegetation Pinus tabulaeformis forest. (Photo by Guo Ke) Vol.24 No.4 2010 Ecosystem Protection Phyllostachys pubescens forest. (Photo by Xie Zongqiang) Pinus, Picea, Betula mixed forest. (Photo by Liu Yonggang) formations and sub-formations. A total of 868 vegetation photos are attached in plates. The Volume II is mainly about the vegetation regionalization map. It describes the geographic position of vegetation regionalization units, and the physiographic conditions, vegetation combination feature, rational utilization of vegetation resource and the protection suggestion of each districts and sub-districts. A Latin-Chinese and Chinese-Latin checklist of more than 8,700 common plant species names appearing in the maps and the instruction is appended (Editorial Committee of Vegetation Map of China, Chinese Academic of Sciences, 2007b). For the convenience of its readers, an accompanying CD-ROM contains all the maps and instructions in the publication. Additionally, all maps are digitized and the related databases are established. A vegetation information Parashorea chinensis forest. (Photo by Zhu Hua) manipulation system is developed. By making use of these databases and the system, readers can splice, cut, zoom, superimpose, mark or color any figures at will. They can also retrieve, extract or calculate all kinds of elements such as points, lines, polygons and fonts; make correlative subject charts and multivariate analyses with natural and social factors; and quickly modify and generate new maps. A technique innovation attempt has been made in compilation of vegetation map in China. Based on remotesensing information and the field investigative data, the more rapid and accurate compilation of vegetation maps on a larger scale is expected to reflect the current vegetation situation and its recent variation. In future, the vegetation information manipulation system will further integrate all older versions of vegetation maps and plant community information. Vegetation Monographs of China The compilation of Vegetation Monographs of China is a major project supported by the State Key Laboratory of Vegetation and Environment Change at the CAS Institute of Botany, with the objective of collecting, analyzing, Bulletin of the Chinese Academy of Sciences 241 BCAS Vol.24 No.4 2010 Sabina pseudosabina subalpine shrubland.

(Photo by Zhao Liqing) complementing and investigating information of vegetation types in an all-round way. This book series elaborates and records the vegetation information in China based on vegetation formations. It is expected to document the up-to-date achievements of vegetation research in an academic, systematic, comprehensive, innovative and informative manner. For each vegetation formation, the record will include aspects of classification systematic position, correlation with each other, research history and questions, geographic distribution, species composition of plant community, ecophysiologic characteristics of dominant species, community structure features, dynamics, functions, main sub-formations and associations and their distribution characteristics, benefits in ecology and economy and the rational utilization. The forthcoming Vegetation Monographs of China will be made up of different volumes mainly based on the classification unit of ‘vegetation type’ in the newly-revised Vegetation Classification System of China. For most complicated types, such as deciduous broad leaved forests and evergreen broad leaved forests, sub-volumes will be separately compiled and published. Some formations with very closed correlations but belonging to different types may be compiled in one volume. In the meantime, work on other monographs in this regard, such as Aneurolepidium chinense Steppe and Meadow, Picea (Spruce) Forest, Fagus Forest, is also under way.
