Commentaries and Prospect on the Geomorphic Information Spectrum

从地貌信息图谱概念的起源——地学信息图谱开始介绍,论述了地貌信息图谱的概念与发展历程,从具体研究的角度归纳了包括地貌形态特征图谱(地面坡谱、剖面谱、二维格局谱系、地形纹理谱)和地貌发育谱在内的地貌信息图谱研究类型及研究现状。结合遥感、计算机和人工智能等技术的发展,分析了知识图谱与信息图谱结合的研究方法在未来地貌研究中的前景,总结了地貌信息提取、地貌信息分类和地貌制图等地貌信息图谱关键技术研究进展,并从构建完备的地貌信息图谱体系、提升地貌信息图谱关键技术、加强全球地貌格局与演变的精细化与定量化研究三方面对未来地貌信息图谱的发展进行了展望,以期为地貌研究工作的数字化、信息化和智能化提供参考,进而服务于国家资源环境重大战略并推进地貌学科的发展。

Geo-information Tupu,which is the origin of the geomorphic information spectrum,is introduced and the concept and development of the geomorphic information spectrum are then discussed.From the perspective of specific research,the research types and status of the geomorphic information spectrum are summarized,including the geomorphic morphological characteristic spectrum(such as,surface slope spectrum,section spectrum,two-dimensional pattern spectrum,and topographic texture spectrum)and the geomorphic development spectrum.Combined with the development of remote sensing,computers,artificial intelligence,and other technologies,the prospect of the combination of knowledge graph and information spectrum in future geomorphic research is analyzed,and the research progress and key technologies of geomorphic information spectrum such as geomorphic information extraction,geomorphic information classification,and geomorphic mapping are summarized.The future development of geomorphic information spectrum is prospected using three aspects:constructing a complete geomorphic information spectrum system,improving key technologies of geomorphic information spectrum,and strengthening the refinement and quantitative research of global geomorphic patterns and evolution.This study can provide a reference for the digitization,informatization,and intellectualization of digital geomorphology to serve as the major strategy for the management of national resources and the environment and promote the development of geomorphology.
