摘要
浅层地温能开发利用方式适宜性分区受地质条件、水文地质条件、岩石的导热性等因素控制。依据长春市地层岩性特征、含水层分布及富水性和岩石导热性,将长春市区划分为3个地层结构区:贾家洼子-八里铺-兴隆沟基岩裂隙含水带以西区(1区),贾家洼子-八里铺-兴隆沟基岩裂隙含水带及其以东到伊通河西岸阶地陡坎区(2区)和伊通河谷地区(3区)。各区的综合导热系数实测值分别是1.168、1.401和1.612。对影响适宜性分区的相关因素进行分析,建立了地源热泵和地下水源热泵适宜区的评价指标体系,并提出了适宜区、较适宜区和不适宜区的划分标准。采用模糊综合评判法对3个地层结构区进行了适宜性评价。评价结果是1区适宜采用地源热泵开采浅层地热资源,2区和3区均适宜采用地下水源热泵开采浅层地热资源。
The conditions of shallow geothermal energy is controlled by geological conditions, hydrogeological conditions and the thermal conductivity of rocks. According to geological and hydrogeological conditions, and analysis of rock thermal conductivity , Changchun urban area can be divided into three stratum structure areas and the No. 1 is bedrock fissure water belt in the west of Jiajiawazi- Balipu- Xinglonggou,the No. 2 is from bedrock fissure water belt in the east of Jiajiawazi- Balipu-Xinglonggou to terrace scarp zone of Yitong River and the No. 3 is the Yitong River valley region. The measured thermal conductivity are 1. 168, 1. 401 and 1. 612 respectively. According to analysis of relevant factors, we establish the evaluation index system of ground-source heat pump andgroundwater source heat pump suitable areas and put forward the optimum area, more appropriate area and unsuitable zone. We use the fuzzy comprehensive evaluation method to evaluate the three stratum structure areas. The results of evaluation is that the No. 1 area is not suitable for groundwater source heat pump and the No. 2,No. 3 area are suitable.
