| Abstract: | The study of karst Geomorphology in China has made great progresses in 20 Century, especially in 90’s. Karstology linking with modern physics, chemistry, biology, mathematics etc. and aimed with computer and advantage analysis technology, many new fields such as hydrological geomorphology, karst hydrogeochemistry, fractal karst geomorphology, karst paleo environment etc. have been developed and the development theoretical and practical karst geomorphology have been accelerated. The paper is stressed on the progress: (1) the evolution of karst landform, many evidences show that the fengcong (peak clusters) landscape will develop to the fenglin (peak forests) landscapes in the favour conditions; (2) karst corrosion intensity and rates are mainly depended on the precipitation, temperature, geomorphological features and characteristics, lithology and geological structures. The karstification is stronger in south China than in north China in the influence of the tropical and subtropical monsoon climate, hot and wet in summer, cold and dry in winter; (3) the deep karst is well developed under the effect of geological structures, the organism is decomposed to produce the organic acids and releases great amount of CO 2; (4) no doubt, karst development is very difficult if there is any bio karst function. The features produced by the microorganism form the base for the macro karst geomorphology; (5) recently, the stalagmites have been employed to study the palaeo climate and environment by the micro laminae technique. Also the prospects have been made for the studying the karst ecological system and environment restoration and improvement, karst paleo environment and groble changes, environment protection and restoration of weathered and damaged speleothem landscape in show caves, experimental and quantitative karst geomorphology etc.. It will be paid more attention to enhance and get more important results in the early of 21 century with the intensive development in the karst regions of southwestern China. |
