中国陆地边界地形剖面谱研究初探

Terrain Profile Spectrum of China Land Border

以根据DEM绘制的中国陆地边界地形剖面作为底图,分别叠加气候区划、土壤区划、植被区划和民族分布,构建了中国陆地边界地形剖面谱。在此基础上,结合4个地形剖面谱及统计结果,分析了各地理要素沿陆地边界的分布格局及其与地形的关系,并阐释了各图谱之间的关联关系。中国陆地边界地形剖面谱具有直观性、简洁性、可量测性、可对比性、图谱性五大特征,为研究线状地理对象地形和其他要素的空间分布特征及相互作用机理提供了新的切入点。

As a base map drawn according to DEM, terrain profile of China land border was overlay the climatic zone, soil zone, vegetation zone and ethnic distribution separately to build terrain profile spectrum of China land border. Based on this, combined with the four terrain profile spectrums and the statistical results, this paper analyzed the distribution pattern of geographic ele- ments along China land border and relationship between them and terrain. It also illustrated the relationship between different spectrums. Terrain profile spectrum of China land border has five characteristics of explicitness, simplicity, scalahility, compara- bility and nature of spectrum. It provides a new entry point to study the spatial distribution of terrain and other elements as well as the interaction mechanism of them along a linear geographic object.
