| 摘 要： | 对大安市典型碱化草原地下水体的各碱化参数与碱化特征进行了探讨。建立了各碱化参数之间的线性回归方程,并对地下水体的碱化危害程度进行了评价。结果表明:各碱化参数之间具有密切的关联性,其中SARp与SSP、SDR和总碱度均为极显著相关。各回归方程的相伴概率p均小于0.0001,具有显著的统计意义。总体上,浅层地下水体的碱化特征均较为明显,其碱化危害程度一般在中等以上;深层地下水体碱化特征较弱,碱化危害程度低。根据FAO(1994)提供的灌溉水质评价标准,各深度地下水灌溉利用均可能造成土壤渗透性的恶化,其影响程度一般为轻微至中等。为促进大安市退化草地改良和地下水的可持续利用提供科学依据。

| 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 rmderate 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 usedfor irrigation,and the degree of deterioation on irrigated use is from slight to moderate. |
