淮北平原浅部地下水换热系统适宜性评价

摘要

安徽省淮北平原广泛分布着宜于利用的浅层地热能,具有以地下水换热方式开发利用的前景。本文利用层次分析（AHP）法,以MapGIS、Access为平台,评价安徽省淮北平原浅部（评价深度50m）地下水换热系统适宜性。参考国内外最新研究成果,结合评价区地质环境特点,在评价因素分类、等级划分和评价指数分级等方面进行了深入研究,评价结果体现了浅部孔隙水系统的基本特点,具有较强的规律性。%Shallow geothermal energy is widely distributed in the Huaibei plain in Anhui Province and is prospective to be utilized in the form of groundwater heat exchange.This paper assessed the applicability of shallow（at depth of 50m） groundwater heat exchange system in the Huibei plain using AHP method based on MapGIS and Access platforms,had a profound study on assessment factor classification,grade division and assessment index grading by reference to latest research results at home and abroad and considering geo-environmental characteristics of the assessed area.The assessment results reflected basic features of shallow pore water that shows a good regular pattern.
