基于GIS-FAHP的石家庄市地下水源热泵适宜性分区

为探明石家庄城区地下水源热泵适宜区分布情况，基于石家庄市的地质、水文地质和环境地质条件构建了地下水源热泵适宜性评价指标体系，包括水文地质条件、水动力条件、水化学条件、环境地质条件和先决条件；利用模糊层次分析法确定了评价指标综合权重，并结合GIS空间分析功能划分了石家庄城区地下水源热泵适宜性分区。结果表明：研究区地下水水源热泵开发利用适宜区分布在靠近滹沱河地区，面积约为19.74 km²，占全区面积的5.85%；较适宜区分布于研究区大部分，面积约为251.22 km²，占全区面积的74.40%；不适宜区主要分布在研究区西北部及东部地下水超采漏斗区，面积约为66.71 km²，占全区面积的19.75%。石家庄市除地下水降落漏斗区及水文地质条件较差地区不适宜作为地下水源热泵开发的地区外，大部分地区较适合利用地下水源热泵技术。

Suitability Zoning of Groundwater Source Heat Pump in Shijiazhuang Based on GIS-FAHP

In order to find out the suitability zoning of groundwater source heat pump in Shijiazhuang City, the suitability evaluation index system of groundwater source heat pump was constructed based on the geological, hydrogeological, and environmental geological conditions, the comprehensive weights of evaluation index were determined by fuzzy AHP method, and the groundwater source heat pump suitability zoning in Shijiazhuang City was divided combining with the spatial analysis function of GIS. The results show that the suitable areas for the development and utilization of the groundwater source heat pumps in the research area are distributed in the Hutuo River area covering about 19.74 km², accounting for 5.85% of the whole area. The relatively suitable areas are distributed in most of the study area, covering an area of about 251.22 km², and accounting for 74.40% of the total area. The suitability zoning is mainly distributed in the area with poor hydrogeological conditions in the northwest and the over-exploitation funnel area in the east of the study area, with an area of about 66.71 km², accounting for 19.75% of the whole area. Except for the underground water funnel area and the areas with poor hydrogeological conditions, which are not suitable for the development of groundwater source heat pumps, most areas in Shijiazhuang are suitable for the utilization of groundwater source heat pump technology.
