Research on the Characteristics of Karst Tourism Geological Resources and Environmental Protection in China Southwest Region

Abstract

The eco-geological environment of the Southwest Karst area is rich in water and heat, mineral resources, and rich in tourism resources. However, it has the dual characteristics of above-ground and underground double-layer karst spatial structure, high mountains and deep water, steep terrain, and poor soil quality. It is easily disturbed by human activities. Ecological degradation has caused ecological and environmental problems such as soil erosion and rocky desertification. On the basis of fully discussing the characteristics of the eco-geological environment in the karst areas in Southwest China, through the analysis of the mechanism of the ecosystem degradation process, it is proposed that the degradation of the karst ecosystem is the cause of the fragile karst eco-geological environment and human activities. On the premise of restricting human activities within the allowable range of the karst ecological environment, develop water resources according to local conditions, rationally use land resources, develop three-dimensional ecological agriculture, tap local economic growth potential, and improve rural ecological restoration and reconstruction based on engineering measures such as energy structure and ecological migration Strategy.
