频谱分析法在宁夏扬黄灌区地下水位预报中的应用

Application of the Method of Frequency Pedigreed to Forecast Ground Water Level on the Irrigation Areas Pumping Water From the Yellow River at the Guhai in Ningxia Region

摘要: 应用频谱分析法对宁夏扬黄灌区的地下水位进行了预测，根据灌区地下水位的变化趋势，提出土壤产生次生盐渍化的潜在危险性，为保证未来时刻该灌区不发生次生盐渍化，提出了一系列切实可行的建议。

Abstract: This paper applied method of frequency pedigreed to forecast ground water level on the irrigation area pumping water from the Yellow River. On the basis of water level varying tendency, the latent danger of secondary salinized soil was presented.
