The present situation of the intensity zonation of karst development is discussed, and the regulation of the vertical zonation of karst development is proposed.

This paper deals with vertical zonation and depth limit of karstifcation.

As porphyry Cu-Mo deposit altered more strongly,it has calculated the vertical zoning of original halo of this deposit through the geochemical measuring data of drill rocks.

They occur respectively as epizone, mesozone and hypozone in space, thus forming vertical zoning of the ore-controlling orefield structures.

Research on primary haloes vertical zoning is an effective way of seeking for concealed orebody and blind orebody.

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.

Spatial distribution of runoff and sediment in the vertical belts of soil erosion chain in loess region of hilly and gully;

Temporal and spatial distribution characteristic of water-sand flow in vertical belts of soil erosion chain in loess region;
