摘要
为了查明南宁市地下水水质是否适宜于开发利用水源热泵,在对南宁市潜水含水层地下水水化学特征调查的基础上,挑选出与水源热泵系统设计和运行相关的水质适宜性评价指标,选用层次分析法(AHP)构建层次结构模型,确定了各个评价指标的权重,并基于GIS平台的空间分析模块进行了地下水水源水质评价分区。结果显示,水源热泵开发水源水质适宜区面积为280.7km2,大多分布在中部市区和东南部良庆区,这些地区地下水多为pH值为7左右的中性水,水硬度较小,对管线和设施没有危害,适合开发地下水源热泵。
In order to identify whether the groundwater quality in Nanning is suitable for the development and utilization of water source heat pump, the water quality suitability evaluation indexes were selected which were related to the design and operation of the water source heat pump system based on the hydrochemical analysis of groundwater samples collected from the uncon- fined aquifer of Nanning city. The hierarchical structure model was developed using the Analytic Hierarchy Process （AHP） to determine the weights for each evaluation index, and the spatial analysis module of the GIS platform was used to obtain the wa- ter quality evaluation zonation of groundwater source. The results showed that the suitable area to develop water source heat pump is 280. 7 km2 located mainly in the central part of Nanning City and Liangqing District. Due to that groundwater in these areas is almost neutral water with little hardness and has no harm to the pipelines and facilities, it is suitable for the develop- ment of groundwater source heat pump.
