江苏丹阳市滨江新城浅层地温能开发利用适宜性分区研究

摘要

To realize the shallow geothermal energy effective exploitation and sustainable utilization in the Binjiang new residential quarter,Danyang City,based on foundation geological condition and rock-soil mass thermophysical property features comprehensive analysis in the area,combined with shallow geothermal energy exploitation and utilization status quo,through the AHP carried out groundwater GSHP and closed-loop GSHP system exploitation and utilization suitability analysis.And then have completed the general GSHP system exploitation and utilization suitability zoning.The quarter has 139km2 of floor space;the groundwater GSHP suitable and rather suitable area total is 101.93km2.Superimposing groundwater and closed-loop GSHP suitability partitioning maps together have found that the overlapping area is 36.27km2 and distributed mainly on the Yangtze River fossil flood plain and stream channel,in which,total closed-loop GSHP suitable and rather suitable area 29.73km2 is included and distributed on slope wash plain.The result can provide a reference for shallow geothermal energy exploitation and utilization in Binjiang new residential quarter.%为了实现丹阳市滨江新城浅层地温能的有效开发和可持续利用,在丹阳市演江新城基础地质条件和岩土体热物性特征综合分析的基础上,结合浅层地温能资源开发利用现状,采用层次分析法进行地下水地源热泵和地埋管地源热泵系统开发利用适宜性分区.在此基础上完成了地源热泵系统开发利用总适宜性分区.丹阳市滨江新城面积139km2,地下水地源热泵的适宜区、较适宜区的总面积为101.93km2;将地下水和地埋管所得出的适宜性分区图叠加到一起,从而得出地下水地源热泵适宜区和较适宜区均为地埋管地源热泵的适宜区,二者均适宜的区域面积为36.27km2,主要分布在长江古漫滩、古河道平原区;仅地埋管地源热泵适宜的区域面积约为29.73km2,主要分布在长江坡积平原地区.成果可为丹阳市滨江新城浅层地温能资源合理开发利用提供借鉴.
