- Abstract:
-
On the basis of the summary of previous use cave indicator system surface environment theory, analysis of their application status in karst rocky desertification, the following understandings were reached: (1) δ18O value of cave sediments indicates that the temperature rainfall conditions, δ13C reaction vegetation conditions, trace and major elements such as Mg/Ca, the Mg/Sr indicators provide supplemental oxygen, carbon isotope record, argumentation, dating technical support, capable of high-resolution surface to interpret environmental changes; (2) karst rocky desertification as a fragile ecological environment in the pattern of global environmental change, can be analyzed by applying research method on pale environmental evolution, but a few scholars have done to try to obtain preliminary results; (3) the use of caves indicators inversion surface of rocky desertification is in its infancy, an is facing many problems.
