The extrusion tectonic model has been widely accepted to explain the strike-slip faults around the Tibetan Plateau. Previous studies indicate that the lower crust flow is the main drive force of the extrusion tectonics. Whether mantle extrusion process occurred during the Cenozoic uplift is a major problem to be addressed, which is significant for understanding the uplift mechanism and tectonic evolution of the Tibetan Plateau.展开更多

One is environmental and ecological effects of land, such as flood controlling, preventing soil erosion, preventing the collapse debris, water conservation and maintenance of biodiversity and conservation of wildlife. Second, it is crop residue use of land, including： treatment of organic waste, decomposing and eliminating contaminants, regulating microclimate and air purification, maintaining and revitalizing rural communities. Third, the geographical landscape effects of land, such as providing idyllic pastures and other entertainment services. In a conclusion, there is little exploration to the ecological effects of rural land. This paper attempts to analyze the environmental problems related to the land transferring in Tongren City.展开更多
