摘　　要：区域性中深层地热资源适宜性评价可为科学合理地开发利用地热资源提供依据。目前,适宜性评价方法多基于定性分析,定量方法较少。基于ArcGIS地理信息系统软件,采用综合指数法对江苏泰州地区进行中深层地热资源勘查适宜性评价,首先对区内地热资源勘查影响因素进行定量赋值,然后运用综合加权评价模型,利用GIS的分析功能计算得出综合评价值,最终将该区地热资源分为开发利用条件良好区、较好区、一般区,其中良好区主要分布于泰州海陵区—姜堰沈高地区以及九龙镇—姜堰俞垛—兴化戴南一线,分区直观、快速、准确。The evaluation of the suitability of middle and deep geothermal resources in the region can provide a basis for the scientific and rational development and utilization of geothermal resources.At present,the suitability evaluation method is mostly based on qualitative analysis,and in lack of quantitative methods.Based on ArcGIS,synthetical index method was used to evaluate the suitability of middle and deep geothermal resource exploration in Taizhou,Jiangsu Province.First of all,it carried out quantitative assignment of the factors influencing geothermal resource exploration in the region,and then used the synthetic weighted model to calculate the comprehensive evaluation value by using the analysis function of GIS.Finally,the geothermal resources in this area were divided into 3 areas of fair areas,moderate areas and ordinary areas,of which the fair areas are mainly distributed in Hailing District of Taizhou City-Shengao Town of Jiangyan District,and Jiulong Town-Yuduo Town of Jiangyan District-Dainan Town of Xinghua City.Zoning is straightforward,fast and accurate.
