摘　　要：讨论了浅层地热能这种新能源的开发前景,并将ArcGIS软件应用于浅层地热能适宜性分区评价中.根据浅层地热能开发特点和研究区资料选定评价因子,在评分系统和权重系统的基础上确定了各个评价因子的综合得分,利用ArcGIS9.3软件快速读取属性数据,并完成矢量数据的转换处理、图形处理、空间叠加等操作.评价结果显示,银川市大部分地区适合采用地下水源热泵开发利用浅层地热能,ArcGIS适用于浅层地热能适宜性分区评价,为合理开发浅层地热能提供了科学依据.The shallow geothermal energy has a good development prospect,and ArcGIS features strong function in spatial processing,therefore the paper holds that ArcGIS can be adopted to assess the suitability division of shallow geothermal energy.The research relies on the characteristics of the shallow geothermal energy exploitation and study region data to determine the assessment factors.The total score of each assessment factor is determined on the basis of assessment system and weight system.The ArcGIS9.3 can be used to quickly read attribute data,and to complete the vector data transformation,images processing and spatial superposition.The result of assessment reveals that the most part of Yinchuan city is suitable to exploit the shallow geothermal energy by using groundwater heat pump.The paper concludes that ArcGIS is appropriate for assessment on the suitability division of shallow geothermal energy,which can provide scientific grounds for the rational exploitation of the shallow geothermal energy.
