| Abstract:A karst ecological research team from the Institute of Karst Geology, Chinese Academy of Geological Sciences in Guilin has been going in for the creative study of the leakage of water and soil in the karst mountain areas of Southwest China since the beginning of the 21th century. A series of progresses in the study of leakage of water and soil were achieved in 2013. The concept, processes and mathematic model of the leakage of water and soil were expounded. By using the site monitoring and advanced isotopic techniques, the team firstly and systemically revealed the quantitative differences and causes of the leakage of water and soil in different geomorphologic positions and different ecological environments of the karst peak cluster depression, built the grade classification standards and the regression model of the soil erosion in the karst areas, created some new water and soil preservation models which combined the biological methods with the engineering and technological rules, and formed the pitaya ecological production industry with good ecological and economic benefits in the karst rocky desertification environment. All these research results can provide technological support and demonstration examples for the treatment of the rocky desertification and the conservation of water and soil in the karst areas of Southwest China. |
