MORPHOMETRY AND EVOLUTION OF FENGLIN KARST IN THE SHUICHENG AREA, WESTERN GUIZHOU, CHINA
Abstract:
Four areas with different styles of fenglin (tower and cone karst) are investigated using morphometric techniques in the Shuicheng area of Guizhou Province. The karsts were formed in the Neogene and were uplifted during the Quaternary, to present elevations of about 1800 m. Measurements were made of the characteristics of 745 cones using maps and aerial photographs supplemented by field investigations. The karst cones are found to be of almost constant slope angle (45-degrees to 47-degrees) regardless of structure, but with a tendency for slightly lower slopes to occur where the carbonates have impure interbeds. Although generally symmetrical in plan, elongation of both cones and intervening depressions appears controlled by major elements of the structure and the general slope of the topography. Spatial analysis shows the cones to be relatively uniformly distributed in three of the four cases studied. Morphometric evidence points strongly to parallel slope evolution of cones. A model is offered of landscape evolution in which sequential development occurs through stages of karst-tableland with dolines to fencong-depression to fenglin-depression and finally to fenglin-plain. Geological control becomes less influential as this development proceeds, with the smaller and more widely spaced cones of the later stages becoming increasingly symmetrical in form
