摘　　要：为了探析引起地温空调井抽回灌效果的主要制约因素,通过单相关系数分析、主成分绝对得分的源解析模型、拟合度检验和多元线性回归的方法分析影响单井回灌效率的影响因素。结果表明:井径、滤水管孔隙率及抽回灌井数比与单井回灌效率的相关性和拟合度较好,故将井径、滤水管孔隙率及抽回灌井数比作为影响单井回灌效率的关键因子,同时分析了单井回灌效率与关键因子的之间的拟合方程及多元线性回归方程,得到了单井回灌效率与关键因子之间的定量关系。In order to search the key factors which can influence the withdraw irrigation effect of ground temperature air-conditioning, the key factors of recharge efficiency of a single well are identified by the single correlation coefficient, APCS-MLR, test of Rsquared and multiple linear regression. The resuits indicate that the relevance and R-Square between the well diameter, the porosity of filter pipe, the ratio of pumping and recharge wells and recharge efficiency of a single well are better. So the well diameter, the porosity of filter pipe, and the ratio of pumping and recharge wells are selected as the key factors. At last, the fitting equation and the corresponding multiple linear regression equation between recharge efficiency of a single well and the key factors are analyzed, and the quantitative relationship between recharge efficiency of a single well and the key factors is got.
