The Dissolution Rate of Carbonate Rock in Southwest of China Based on the Influence Factor Analysis

In this paper, we based on the existing research results, the effects on dissolution rate (DR) of carbonate rock are analyzed for three factors: mineral and chemical component of carbonate rock, atmospheric temperature and rainfall. The formula is established on the relation between rainfall and DR. Considering mineral and chemical component of carbonate rock by the difference of research area. The results show that: Precipitation is positively correlated with carbonate dissolution, and the influence of temperature is of a stage. The DR of carbonate rocks in Guilin is calculated to be 79.65mm/ka, which is calculated from the mineral chemical composition of carbonate rocks in Yaoshan Scenic Area, Guilin. The average regional DR is 95.16mm/ka; the calculation formula of DR of carbonate rock proposed in this paper is suitable for the southwest of China.
