| 摘要: |
| A Study on Modern Karstification Intensity of Typical Corrosional Hill System in South China |
| The typical corrosional hill system is mainly distributed in Lianyuan-Xinhua County,around Xuefeng mountain area.There are four karst landform types,namely clustered-hill valley,ridged-hill valley,peak-cluster depression and gentle-hill valley,which have quite different karst development histories and complex features.;Based on the discussion of hydrochemical features of karst water in various geomorphological systems and its corrosion capacity,the author calculated the corrosion velocity by using hydrochemical equilibrium method and analysed varied causes of modern karstification intensity.The average corrosion velocity in corrosional hill is 25.19 m 3·km -2 ·a -1 ,ranging form 10.26 to 30.04 m 3·km -2 ·a -1 , which led the semi-karst formation to the prominent macro-geomorphologhical pattern in the study area. |
