基于科里奥利力对河流影响下水土流失防治的研究

Prevention of Soil Erosion Under the Influence of Rivers Based on Coriolis Force

随着经济的快速发展,国民为了对美好生活的追求而破坏生态环境,使地表土壤裸露,逐渐沙化,易受外力侵蚀,加剧水土流失。地球上还存在着一种无形的力量不断地改变着人类所生存的地理环境,它就是科里奥利力。中国地势西高东低,多数河流自西向东流,在科里奥利力的作用下受到偏南的地转偏向力,使得河流对南岸冲刷的力度较北岸来说更强。随着地理环境变化在不同的地区所造成的影响各有不同。同时科里奥利力也对中国季风、洋流的方向有影响,从而一定程度上影响中国降水的形成。降水的强度随之又影响水土流失的强度。在土质疏松地区,应加大对水土流失的保护,加强当地的生态文明建设,提高当地的经济发展。

With the rapid development of economy,the people,in pursuit of a better life,have destroyed the ecological environment,exposing the surface soil,gradual desertification,being vulnerable to external erosion,and aggravating water and soil loss.There is also an invisible force on the earth that constantly changes the geographical environment where human beings live.It is the Coriolis force.The terrain of China is high in the west and low in the east.Most rivers flow from west to east.Under the action of Coriolis force,they are subject to the geostrophic deflection force to the south,making the river scouring the south bank stronger than the north bank.With the change of geographical environment,the impacts in different regions are different.At the same time,the Coriolis force also affects the direction of China's monsoon and ocean current,thus affecting the formation of precipitation in China to a certain extent.The intensity of precipitation then affects the intensity of water and soil loss.In areas with loose soil,the protection of water and soil loss should be strengthened,the construction of local ecological civilization should be strengthened,and the local economic development should be improved.
