摘要: 为提高水源热泵适宜性评价结果的合理性,利用富水性、回灌率、渗透系数、含水层厚度等13个参评因子构建了西安地区浅层承压水水源热泵适宜性评价指标体系。通过层次分析法、基尼系数赋权法确定评价指标的权重,在GIS技术支持下,建立适宜性二级评价模型,将适宜性划分为4个等级,并分析了浅层承压水水源热泵适宜性分布状况。结果表明:浅层承压水水源热泵适宜区面积为1 144.32 km2,较适宜区面积为1 393.57 km2,一般适宜区面积为762.48 km2,不适宜区面积为6 807.63 km2。适宜区总面积达3 300.36 km2,占人类主要活动区面积的76.98%,浅层承压水水源热泵技术有较好的应用前景。

Abstract: A suitability evaluation system for shallow confined water source heat pump in Xi’an is constructed in consideration of thirteen factors including water abundance, reinjection efficiency, hydraulic conductivity, and aquifer thickness. The weight of each factor is determined by using analytic hierarchy process method and Gini coefficient method. In addition, GIS technology is employed to build up a two-level evaluation model for spatial analysis, and the suitability of the study area is divided into four levels. Results reveal that the area of favorable region for constructing water source heat pump system in the study area is 1144.32 km2,the area of suitable region is 1393.57 km2, the area of moderately suitable region is 762.48 km2, and the area of unsuitable region is 6807.63 km2. The total area of suitable region is 3300.36 km2, accounting for 76.98% of the human activity area, indicating that shallow confined water source heat pump has a good prospect in Xi’an city.
