( 3 ) sensitivity analyses were conducted for parameters in unsaturated soil conductivity model which was derived from redistribution process . the results calculated from measured data indicate that the sensitivities of conductivity to parameter b and n are higher than the other parameters ( 3 )对由再分布过程推求的土壤非饱和导水率模型中的参数进行了敏感性分析，根据实测资料的计算表明，非饱和导水率对参数b和n的敏感性均大于其它参数。
