【摘要】 根据顺义地区的土壤分布状况，选择典型小区，利用排水沟进行了地下水回补的入渗试验，分析了不同处理对入渗效果的影响。试验结果表明，该地区地下水回补效果明显。用最小二乘法拟合渗透系数，同时对某一处理的渗透系数进行回归显著性检验，效果显著，表明所得渗透系数值具有可靠性。更多还原

【Abstract】 According to the distribution of soil in Shunyi area, the typical small region is choosen. The infiltration experiment of ground water recharge is carried out,and the influence factors of infiltration is analysed. Experiment results show that recharge of ground water is obvious in this area. The value of hydraulic conductivity is estimated with least square method and is compared. The value of hydraulic conductivity derived from some treatment is tested and the results is reliable.更多还原
