基于层次分析法的关中盆地主要城市浅层地热能适宜性分区特征研究

Research on suitability evaluation of shallow geothermal energy of major cities in Guanzhong basin

浅层地热能是一种可用于建筑节能的新型能源,它具有无污染、可再生、分布广、能量大以及可就近利用等诸多优势,开发利用前景广阔。根据关中盆地主要城市的工程地质、水文地质、环境地质条件等因素,分别建立了每个城市地下水热泵和地埋管热泵系统的适宜分区评价体系,运用层次分析法对关中盆地主要城市的浅层地热能适宜性分区进行综合评价。将各个城市地下水热泵和地埋管热泵适宜性分区划分为适宜区、较适宜区及不适宜区,综合分区在两者的基础上进行,并优先选择地下水热泵。旨在有效地丰富浅层地温能勘察评价与开发利用的理论、奠定浅层地温能可利用资源量的计算基础,为构建我国环境友好型社会服务。

Shallow geothermal energy that has many advantages of nonpolluting,renewable,widely distributed,energy is an advanced technology and it has broad prospects for development and utilization. According factors of regional engineering geological conditions,environmental geological conditions and hydro geological conditions and,We have established zoning suitability evaluation system of groundwater heat pumps and ground heat pump,and then get a comprehensive evaluation of the suitability district of shallowgeothermal energy in every cities. Based on the results of the suitability assessment,Evaluate of the main city of shallowgeothermal energy resources,including heat capacity calculation,heat power calculation and thermal potential is calculated. in order to Increase with the theories of the development and utilization of shallow ground temperature can survey and evaluation effectively,Lay the foundation of exploitation and utilization of shallowground temperature. This method is designed to provide a scientific basis and support for the development and utilization of guanzhong basin of shallowgeothermal energy,It has a very important significance to build a resource-saving and environment-friendly society,protect national energy security,improve our existing energy structure,promote the realization of the goal of national energy strategy.
