Abstract

The parameters of alkalization including SAR, SDR, SSP, RSC, pH and total alkalinity of groundwater are calculated in order to accelerate deteriorated grassland improvement and sustainable utilization of groundwater. The equations of linear regression in these parameters of alkalization are analysed. The results show that: (1) sodium adsorption ratio (SAR) is linearly related to SSP, SDR and total alkalinity, the regression equations between SAR and SSP, SDR and total alkalinity are significant (p < 0.0001), (2) shallow groundwater takes on a obvious characteristics of alkalization, and the harm of alkalization is from moderate to very high, deep groundwater has a slight characteristics of alkalization, and extent of harm is very small, and (3) based on the irrigation water quality evaluation criterions by FAO (1994), the soil permeability could be deteriorated when the groundwater is used for irrigation, and the degree of deterioration on irrigated use is from slight to moderate.
