Influence of the Uplift of Tibetan Plateau on China's Human Geography Environment:Hu Line and Its Responding
China has a vast territory,and its population,land,arable land,and level of development are very uneven.The famous Hu Huanyong Line(Hu Line)has been found by well-known Geographer Hu Huanyong in 1935.The Chinese Mainland is divided into eastern and western parts by Hu Line,which reveals the significant spatial relationship between human activity and natural environment.There is a significant difference between the eastern and western sides of Hu Line.The reasons for this difference are multifaceted,and the natural environment near the surface and the exchange of material and energy within the earth play an important role.Research and exploration have shown that the collision and compression of the Indian subcontinent and Eurasian continental plates driving the uplift of the Himalayan orogenic belt on the southern edge of the plateau is the fundamental reason.The protrusion of the Himalayan orogenic belt obstructs the northward movement of the warm and humid climate from the south of the Indian Ocean,and influences the westerly belt,causing drought and desertification in the northwest region of China.Under the influence of force systems,the crustal and mantle materials undergo re-differentiation and adjustment,resulting in crustal shortening and thickening,and overall plateau uplift.This not only leads to significant changes in precipitation,temperature,population,arable land,and ecological environment in the eastern and western regions,but also leads to strong variations and uneven distribution of geophysical fields.The key to the development of the western region lies in water.If water enters,people will enter,culture will enter,technology will enter,and technology will develop rapidly.The living and living environment of the people in the western region is constantly optimized,and society will be more peaceful.The eastern region is continuously strengthening the development and utilization of underground space,while the western region is looking forward to the implementation of the Hongqi River Project,maintaining the ecological environment,and building billions of acres of modern farmland,pastures,and oases.The joint development and construction of the eastern and western regions of China is very important,and the rice bowl must always be in one's own hands.
