Progresses and important activities of karst research during the 11th Five-Year Plan in China

International karst research center is founded in Guilin and fruitful progresses both in theory and practice research have been got during the 11th Five-Year Plan.Theoretically,the karst dynamics is developed in light of the earth system science views and modern automatic testing measures.And the new growing point,karst ecology,not only has brought to light the fragility of the karst eco-system and the changes in soil quality as well as the speciation law of some soil nutrient elements in southwest China,but also selected a lot of special species that suit the karst environments.In the field of global change researches,the dissolved inorganic carbon of the karst hydro-cycle has been found as an important part in global carbon cycle and many climatic supersede indicators has been used to deepen the study on palaeo-environmental records of the cave stalagmites.Furthermore,new technology and software is used to study the available evaluation methods in the water quality and quantity evaluation of karst underground water.Practically,the geological survey data,including the karst water resources in southwest China and the karst rocky desertification environments as well as the soil erosion datum,has played important role in the national goal and significant society demands on one hand.And on the other hand,typical geo-model is formed in the gas and oil exploration in karst areas,the South China Karst is reported and listed successfully as the world natural heritage,and the new monitor and early warning techniques of karst collapse are successfully used to prevent and cure karst collapse in the practical engineering.
