秋浇对内蒙古义长灌域地下水动态的影响
Impact of autumn irrigation on groundwater dynamics in Yichang Irrigation Sub-district,Inner Mongolia
摘要
Abstract
Autumn irrigation is a unique scheme in Hetao Irrigation District,and it plays a vital role in the sustainable development of agricultural irrigation. However, autumn irrigation also has an impact on groundwater table and groundwater quality.In order to understand this impact better,Yichang Irrigation Sub-district in Inner Mongolia was studied.Both quantity and quality of irrigation water and discharged water were analyzed from monitoring data from 1981 to 2010.It was found that exported salt in discharged water accounted for 53.81% of the whole irrigation period.Groundwater table reached peak value after autumn irrigation, therefore irrigation,especially autumn irrigation,controlled dynamics of groundwater table.But there was no significant change in total dissolved solid (TDS)before and after autumn irrigation.A reasonable ratio of discharged to irrigation water and measures to improve water discharge efficiency need to be further studied.关键词
