摘要:浅层地温(热)能是一种可再生的新型环保能源,地下水地源热泵系统是开发利用浅层地热能的一种方式。层次分析法(AHP)能够充分利用专家的知识和经验,但是无法克服主观随意性带来的偏差:摘权系数法是一种客观的评价方法,但是不能反映决策者的偏好。结合南京的地质、水文地质条件、水温场、水化学条件等,提出基于AHP和权系数法的综合评价方法,对南京市地下水地源热泵系统应用适宜性进行分区,得到适宜区、较适宜区和不适宜区的分布范围和面积,对今后的开发利用工作具有指导意义。

Abstract: Shallow geothermal energy is a kind of green and renewable energy sources. Groundwater source heat pumps are often used to exploit the new energy. It is well known that AHP can take full advantage of sub-jective views of experts, but it is also accompanied by the bias caused by human factors. On the contrary, en-tropy weight method, which is an objective evaluation method, does not reflect preferences of decision makers. Based on AHP and entropy weight method, a new method is put forward, which is the linear weighted summa-tion method. According to the geological and hydrogeological conditions, the groundwater temperature field, the groundwater chemistry conditions etc. , the suitability of groundwater source heat pumps in Nanjing is evaluated with the linear weighted summation method. The distribution areas of suitable region, sub-suitable region and unsuitable region are attained. The results provide scientific advice for rational and appropriate application of groundwater source heat pumps
