层次分析法是一种定性和定量分析相结合的多目标决策分析方法,在很多领域都得到广泛的应用。本文运用层次分析法进行银川市地下水水源热泵适宜性分区评价,确定浅层地热能适宜性分区评价体系中的各评价指标的权重。在此基础上,利用权重系统和评分系统进行适宜性分区评价,评价结果显示银川市除局部地区外,大部分地区适宜采用地下水水源热泵开采浅层地热能,评价结果与客观情况基本吻合,分区结果合理可靠,为银川市浅层地热能的合理开发利用提供借鉴和参考。
Analytic Hierarchy Process (AHP) is a multi-objective decision analysis method which is a combination of qualitative and quantitative analysis. It has been widely used in many fields. In this paper, the analytic hierarchy process (AHP) is used to evaluate the suitability of groundwater source heat pump in Yinchuan City, and the weight of each evaluation index in the evaluation system of shallow geothermal energy suitability is determined. On the basis of this, we use the weight system and the scoring system to carry on the appraisal of suitability. The appraisal results show that except for some areas in Yinchuan City, the groundwater source heat pump is suitable for the exploitation of shallow geothermal energy in most areas. The appraisal result basically agrees with the objective situation, The results are reasonable and reliable, providing a reference for the reasonable development and utilization of shallow geothermal energy in Yinchuan.
