基于层次分析法的沈阳市地下水地源热泵适宜性研究

为了使沈阳市地下水地源热泵系统能健康有序地发展，利用层次分析（AHP）法，以MapGIS为平台，综合考虑工作区地质水文地质条件、地下水动力场、地下水化学特征等因素，建立了地下水富水性、地下水回灌能力、地下水水位埋深、地下水径流条件、含水层渗透系数、地下水Fe含量、地下水总硬度等7项评价指标，对沈阳市辖9区范围内地下水地源热泵适宜性进行了评价。结合沈阳市已建地下水地源热泵工程调查情况表明，沈阳市已建地下水地源热泵工程大多集中在所规划的适宜区内，建立的评价指标体系合理，评价结果可以作为沈阳市浅层地温能开发利用规划的依据。

Suitability of Groundwater Source Heat Pump System Based on Analytic Hierarchy Process in Shenyang

In order to make groundwater source heat pump system rational and orderly development in Shenyang, the suitability of groundwater source heat pump system of nine districts in Shenyang is evaluated by the analytic hierarchy method （AHP）, based on McqgGIS platJbrm, cmnprehensively considering geological and hydro geological conditions, groundwater dynamic field and groundwater chemical char- ~teristics of the work area, setting up seven evaluation indexes, including the groundwater abundance, groundwater recharge ctq~abilit）, em- bedded depth of groundwater table, groundwater flow, permeability coefficient of aquifer, the Fe content and total hardness of groundwater. The evaluation results show that most existed groundwater source heat pump projects are inside the suitable planning area of Shenyang, the comprehensive evaluation index system is reasonable, evaluation results can be used as the basis of developing and utilizing shallow geother- mal ener in Shenyang.
