Research Review of Karst Mountain Eco-environmental Geological Problems and Sustainable Development in Yunnan

Karst area accounted for 28.14 percent of the province's area in Yunnan, and environmental geological problems come out frequently, such as rocky, Karst drought, Karst collapse, Karst water pollution the like. Predecessors made indepth explorations and researches from different perspectives in different areas, and achieved fruitful results. But the study of geological environmental carrying capacity, evaluation system of environmental geological problems, Karst water pollution, Karst mountain ecological environment mode need to be deepened. This paper is about the environmental geological problems in Karst mountains and study on sustainable development in Yunnan, with a focus on the contradictions of human activities and Karst geological environment, based on people-ground system, and make a comprehensive survey of environmental geology, which combined with the evaluation of ecological carrying capacity, and proposes solutions to environmental and geological problems, and explores the reconstruction programs about karst mountains ecological and geological environment and the sustainable development model from the perspective of environmental geology.
