中国自然景观综合信息图谱研究

地学图谱是用可视化形式 ,有规律的图形来表现空间信息 ,地学信息图谱是计算机化的地学图谱 ,是地图可视化的一种新形式。中国自然景观综合信息图谱是地学信息图谱研究的一个重要内容。本文首先介绍了自然景观信息图谱的基本概念 ;然后探讨中国自然景观综合信息图谱设计与提炼的技术路线 ,以及中国自然景观综合信息图谱与自然景观单要素信息图谱的提炼方法 ,并给出具体实例 ;最后简要介绍了中国自然景观综合信息图谱信息系统的研制。通过对中国自然景观综合信息图谱的设计与提炼 ,探讨了地学信息图谱的研究思路和技术路线 ,为地学信息图谱的进一步研究 ,提供了可借鉴的方法。

Research on Complex Informatic TuPu of Natural Landscape in China

Geomatic TuPu presents spatial information in well regulated form of graphics Geo informatic TuPu is a computer based geomatic TuPu, which is a kind of spatial information visualization, and a new form of cartographic products in the era of information It aims to provide users with the deeply processed, higher level of geographic information products supported by the technologies of computer, GIS, visualization and VR Complex informatic Tupu of natural landscape, according to spatial scale, may be divided into macroscopic landscape informatic TuPu, mid cosmic landscape informatic TuPu and microcosmic landscape informatic TuPu Chinese complex informatic TuPu of natural landscape is a nationwide macroscopic landscape informatic TuPu, and its typologic grades include landscape zone, landscape second zone,landscape genre According to the composing elements of natural landscape, natural landscape informatic TuPu can be divided into single element informatic TuPu of natural landscape and complex informatic TuPu of natural landscape The method of “from top to bottom” is used to study complex informatic TuPu of natural landscape in China, that is, the complex informatic TuPu in China is dealt with level by level from landscape zone to landscape second zone and then to landscape genre As Chinese complex informatic Tupu of natural landscape is a kind of macroscopic landscape informatic TuPu and the outlines of TuPu are changed very slowly with time, the focus of research is put on the changes of the graphic outline but the macroscopic change of geographical spatial distribution rules The technological flow of retrieval for complex informatic TuPu of natural landscape in China includes design for the representation of TuPu, type partition and outline determining of natural landscape, building of index system, design for database structure, and development of TuPu information system This paper introduces the basic concept of informatic TuPu of natural landscape firstly; then, discusses the way of studying complex informatic TuPu of natural landscape in China; thirdly, provides the way of retrieval for complex informatic TuPu and single element informatic TuPu by taking Chinese natural landscape as a case; lastly, introduces simply the development of TuPu information system
