THE CLASSIFICATION OF TOPOGRAPHIC EVOLUTION IN THE DRAINAGE BASIN AROUND THE TAIDE PLATEAU AND THE ERODING TREND UPON THE TOP OF THE PLATEAU |
| |
| Abstract: | According to the theory of topographic evolution, the article contains
mainly two points as follows.
1, Counting the value of the erosion integration and the density of the
drainages of the basin, then, classifing the basins according to the di-
fference of the two variations by the method of the hierarchical cluster. 7
kinds of types have been distinguished.
2, In the foundation of the types above, two variations are caculated,
which are the areas of the plateau top in each basin and its slope. So 5 ki-
nds of types about intensity of eroding upon the top have been recognized
finally. |
