青铜峡灌区引黄用水与地下水位响应关系分析

分析青铜峡灌区引黄用水与地下水位响应关系,对于查明影响地下水位变化的关键因子并采取措施,缓解土壤盐碱化对农业生产的影响,维持灌区可持续发展及灌区生态健康和环境友好至关重要。本文通过分析灌区地下水位动态变化及与引黄用水的响应关系,得出青铜峡灌区年内地下水埋深与引黄水量存在着密切的负相关关系,说明灌区引黄水量变化是地下水位变化的主要原因之一。

Analysis of response correlation between the Yellow River water and groundwater level in Qingtongxia irrigation district

There is a colose eorrelation between the Yellow River water and the ground water level.To understand the key fuctors and take measure can relax the influence of soil salination on agriculture produetion and maintain sustainable development,ecological health and environment-friendly of irrgation regions.Through the analysis of relation between the Yellow River water and groudwater level,the paper got the result that there is a close negative correlation between them,the change of water volume from Yellow River is one of the main reasons of the change of groudwater level.
