摘  要:在分析镇江市的区域地质、水文地质与环境地质条件与岩土热物理、热响应特征等基础上,根据层次分析法的原理,从目标层、亚目标层与指标层分别建立了地下水地源热泵与地埋管地源热泵系统的适宜分区指标体系.利用ArcGIS空间分析功能,对镇江市3847 km^(2)区域进行1 km×1 km的网格化空间离散,集成层次分析评价模型,计算各单元格的适宜性指数,并对栅格结构适宜性指数分区图进行矢量化,从而得出浅层地温能的开发利用方式适宜性分区.综合分区在两者的基础上利用ArcGIS的图层叠加空间分析功能得出.该研究成果可为镇江市浅层地温能开发利用方式的选择提供科学依据.Based on the conditions of regional geology,hydrogeology and environmental geology in Zhenjiang City,the characteristics of rock and soil thermophysics and thermal response are analyzed.According to the principle of analytic hierarchy process,the suitable zoning index system of groundwater ground source heat pump system and buried pipe ground source heat pump system is established from the target layer,sub-target layer and index layer,respectively.By using the spatial analysis function of ArcGIS,the spatial discretization of 1 km×1 km grid was conducted in the area of 3847 km^(2) in Zhenjiang City.Then,the suitability index of each cell is calculated by integrating the analytic hierarchy process evaluation model.The grid structure suitability index zoning map is vectorized,and the suitability zoning of shallow geothermal energy development and usage mode is obtained.The final comprehensive zoning is obtained using the spatial analysis function of ArcGIS layer overlay on the basis of the two.The research results can provide a scientific basis for selecting shallow geothermal energy development and usage mode in Zhenjiang City.
