The Relationship Between Groundwater Pollution and the Migration of Ancient Chinese Capitals
There is no scientific explanation for the frequent migration of ancient Chinese dynasties'capitals.Natural,political,military,economic,cultural and other factors do not constitute the endogenous power of capital migration.Choosing the right"Waterland"is the basic requirement of ancient capital construction.Waterland refers to a place with abundant water resources.Because the drinking water of city residents mainly depends on drilling wells to obtain shallow groundwater,groundwater pollution has become an eternal nightmare of ancient Chinese capitals,including Xi'an,Luoyang,Beijing and other famous ancient capitals in the northern China.The daily pollutants in the groundwater of ancient cities in China mainly include excrement of human and animal,domestic sewage and all kinds of garbage.Carcasses of human and animal and destroyed buildings are also the sources of pollution.The ancients solved the problem of drinking water by digging new wells,and transporting water and diverting water into the city.However,it was a forced choice for the ancient Chinese capital to abandon the city and move to another place.The duration of the ancient capital is closely related to the richness of water resources and water quality.Groundwater pollution is an endogenous power for the frequent migration of ancient Chinese capitals.Most of the ancient capitals and cities of China completed their life cycles from prosperity to decline due to groundwater pollution.
