Abstract:
The scientific term of Karst in Europe and Yanrong in China is originated from the cognitive history and different orientation of the same objective entity (carbonate topography). The progress of Yanrong research in China has shifted from focusing on the deconstructive engineering properties and resource utilization by karst dissolution dynamics to the systematic construction of karst dynamics, karst biogeochemistry and karst ecosystem productivity. In the process of serving the needs of social and economic development, Chinese karst studies have discovered and improved the contradictory movement mechanism of "deconstruction" and "construction" of karst system and its space-time scale and effect changed by human activities, which have been transformed into the theory and technology serving for regional resource environmental management and sustainable development, including controlling karst rocky desertification. In-depth research on the movement law of opposition and unity between erosion base level evolution that controls the deconstruction of karst ecosystem in small watershed and vegetation succession that improves the construction of karst ecosystem will contribute to the construction of ecological community of karst mountain, water, fields, forests, lakes and grass and serve for sustainable development and coping with global change.
