中文摘要：
基于敏感性分析理论，以某地下水源热泵系统夏季运行为例，选取典型观测点温度值及回灌水热量影响范围作为模型输出结果，从局部和全局定性、定量地讨论了热泵系统特定水流和热源条件下地下水热量运移模拟中参数的敏感性问题。结果表明：模型输出结果对所选参数的局部敏感性程度和趋势差别明显；全局敏感性分析中其他参数不同取值对待分析参数敏感性各参数间共同作用对模型均存在影响，各参数组合全局敏感性趋势变化基本一致，模型稳定性较好。
英文摘要：
Based on the theory of sensitivity analysis, the local/global sensitivity analysis of parameters for the modeling of thermal transport in aquifer under special groundwater flow and heat source conditions was carried out with the summer running of GWHP system as a study case, by taking the temperature of typical observation points and thermal affected zone （TAZ） of injecting water at the end of summer as the model outputs. The results showed that the sensitivity of each modeling output was various for the different parameter in local analysis. The orders of local sensitivity coefficients of the nine parameters for two modeling outputs were almost coincident. In global sensitivity analysis, the sensitivity of the parameter being investigated was influenced by the different values of other parameters. The two modeling outputs almost had the same variation tendency of global sensitivity with different parameter combinations. The numerical model was stable.
