Groundwater Quality Affected by Yellow River Irrigated Agriculture in Northern Suburb of Yinchuan, China
Abstract:
Groundwater quality is affected by agricultural irrigation easily. Northern suburb of Yinchuan is a part of Yellow River irrigation area. Shallow buried depth of groundwater and sandy aeration bring about high vulnerability which is adverse to prevent pollution. As source of drinking water, the quality of groundwater needs to be assessed eagerly. The analysis indicated primary pollution comes from agriculture activities. Pollution loss ratio was adopted to determine the level of pollution. The results show that pollution caused by high salinity is more prominent than nitrogen pollution. The pollution is considerable and a few pieces of advice were proposed in order to improve groundwater quality.
