Based on the idea of Geo-info Tupu and digital mountain altitudinal belts(digital MABs),the objective of this paper is to construct the models of multi-scales spatial patterns in altitudinal belts and develop the digital framework that identifies the horizontal and vertical differentiation from multi-source data.

Soil formation factors and comparison among different altitudinal zonations of the soils on northern slope of the Taibai Mountains;

Fairly careful studies are made on the profiles and altitudinal zonation of the investigations in this very area, providing a good understanding on the distribution of corresponding soil resources and rather complete materials for teaching and fieldwork practices.

It has the functionalities of graphic analysis,data organization and management,real-time connections among geographic features,data and graphics of mountain altitudinal belt spectra,real-time conversion between relative and absolute altitude of MABIS,multi-format data output,and more friendly interfaces.
