摘 要:《中华人民共和国地貌图集(1∶100万)》是全面反映我国地貌宏观规律、揭示区域地貌空间分异的国家级基本比例尺基础性图集。本文回顾了我国地貌制图的发展历程,阐述了全国百万数字地貌遥感综合解译和地貌图集编制的过程,从图集内容结构、数值地貌分类体系、数据基础、地貌遥感解析技术、数字地貌数据库共享系统、地貌图图例系统、图集编制及印刷技术、图集蝴蝶装帧技术等方面详细分析了地貌图集的研究内容和编制特色。地貌图集研究成果已在全国土地调查、区域规划、环境保护和灾害监测等多个方面得到广泛应用。Geomorphological maps are one of the most fundamental maps of the natural environment.They have been used widely in scientific research,resource exploration and extraction,education,and military affairs.An editorial committee was founded in 2001 to collect materials for a set of new 1:1,000,000 geomorphological maps of China.A digital geomorphological database was created in ArcGIS with visual interpretation from Landsat TM/ETM imageries,SRTM-DEM,and published geomorphological maps.The maps were compiled from this database with MAPGIS and published by Science Press in 2009. The characteristics of the main map are as follows.Firstly,Landsat TM/ETM imagery,published geomorphological maps or sketches,geographical base maps,geological maps,and other thematic maps were collected,uniformly geometrically rectified,clipped into uniform sheets,and stored in the foundation database.Secondly,a uniform geomorphological classification was built by combining morphology and genesis types,which comprises seven hierarchical layers: basic morphology,genesis,sub-genesis,morphology,sub-morphology,slope and aspect,material composition and lithology.These layers were stored in the database during visual image interpretation.Thirdly,according to the three-leveled representation of surface relief and bathymetry in China,color and symbol bases were built in MAPGIS,and visualization standards and procedures were developed.In particular,computer cartography of the desert regions was improved greatly compared with hand-drawing.Finally,a uniform 1:1,000,000 geomorphological map was produced and compiled in MAPGIS. The 1:1.000,000 geomorphological map of China will fill the blanks in basic scale thematic maps,which could lead to significant progress in geomorphology and cartography.It is expected that the geomorphological database will be used widely in many fields.
