摘要
在对地学信息图谱研究进展分析总结的基础上,阐述土壤侵蚀信息图谱的概念,及土壤侵蚀类型信息图谱、土壤侵蚀空间格局图谱和水土流失过程信息图谱3种基本类型的内涵,探讨土壤侵蚀信息图谱的构建过程,提出土壤侵蚀信息图谱的内容与表达方式,并对土壤侵蚀信息图谱的意义和发展进行展望。
Based on the analysis and summary of research progresses in Geo-information tupu, the concept of soil erosion information tupu and the connotation of three basic types information tupu that contain soil erosion types, spatial pattern of soil erosion, processes of soil and water loss are expounded. In this paper, the construction process of soil erosion information tupu is discussed, contents and ways of the expression are proposed, and the signification and developmental perspective of soil erosion informatie tupu were described also.
