地理学是一门研究各种地理要素的时空分布、演化过程,以及相互作用机制的综合性学科.随着现实世界从二元空间向三元世界的演进,对地理信息内涵的理解、表达和挖掘亟待进一步加深与扩展.现有以“位置+几何+属性”的地理信息表达模式难以支撑各种地理要素及其规律的表达.本文从地理学视角出发,立足三元世界理念,梳理了信息要素及其转变成地理信息的过程,形成了以时间、地点、人物、事物、事件、现象和场景“七要素”的信息表达体系,并从地理语义、空间位置、几何形态、属性特性、要素关系、演化过程、作用机制7个地理维度上对其进行解读.实现了地理学视角下对地理信息内涵的全方位分类和描述,为面向地理学综合集成研究的地理信息多维描述与计算分析提供理论支撑.

The Niangzhong diabase dikes, dated at 138.1 ± 0.4 Ma, are located within the outcrop area of the Comei large igneous province (LIP). These diabase samples can be divided into two groups:samples in Group 1 show varying MgO (1.50 wt.%-10.25 wt.%) and TiO2
The loess depositions in Shandong Province are important parts of loess records in east- ern China, but their origin and genetic linkage between the Yellow River and the Chinese Loess Plateau are still unclear. This paper presents the detrital-zircon evid
Emeishan large igneous province (ELIP), one of the largest continental volcanic provinc-es worldwide (e. g., Karoo), is extensively distributed along the western margin of the Yangtze Block. Even though the consensus that the ELIP is of a plume-related or
It has been suggested that the carbonated mantle reflected by Mg-Zn isotopic anomalies of Cenozoic intraplate basalts from East Asia coincides with the stagnant West Pacific slab in the man- tle transition zone. However, the northern boundary of such carb
A preliminary survey of silver isotopic composition in four polymetallic ores in eastern China shows a larger variation in δ109Ag from-0.014‰to+0.983‰, which is within the total ranges for the entire respective ore deposit types worldwide. The diversity o
The Huayangchuan ore belt is located in the western segment of Xiaoqinling Orogen in the southern margin of the North China Craton (NCC), and hosts voluminous magmatism and signifi- cant U-REE-Mo-Cu-Fe polymetallic mineralization. However, geochronologica
Many studies focus on mineralization of huge magnetite ore deposits and petrogenesis of their large-volume host rocks. However, magma generation of those small-scale intrusions with enrich- ment of magnetite is poorly reported and paid attention to. We he
We present detailed geochronological, geochemical, and zircon Hf isotopic data for Late Paleozoic granitic rocks from Handagai and Zhonghe plutons in the Xing\'an Block, NE China, aiming to provide constraints on their origin and tectonic implications.
With comprehensive two-dimensional gas chromatography linked to time-of-flight mass spectrometry (GC × GC-TOFMS), ten light hydrocarbon (LH) compounds were qualitatively and quantitatively studied in light hydrocarbons (LHs) components of crude oils. For
Located in Luoning County, western Henan Province, Central China, the Zhonghe Ag- Pb-Zn ore field, is a newly discovered deposit in the Xiaoshan District. Ore bodies controlled by NNW Faults occur as veins within the Paleoproterozoic Xiong \' er Group o
