摘　　要：我国拥有丰富的水热型中低温地热资源,与烘干、工艺加热等工业生产过程所需的温位接近,具有较大的应用潜力。在调研国内外成熟的地热能工业应用场景的基础上,利用层次分析法,选取资源性、技术性、经济性、安全性4个方面,建立地热能工业应用品类评价指标体系。通过构造判断矩阵、层次单排序及一致性检验等步骤,明确了安全环保健康、最低需求水温、最低需求水量、年利用小时数是对地热能工业应用评价影响较大的4个重要指标,其权重分别为0.26、0.245、0.135、0.083。利用该评价指标体系对各应用场景进行综合评价,结果表明,牛奶杀菌(巴氏法)、皮革鞣制、大米干燥、蔬菜干燥这4种应用场景综合评价得分高,具有地热资源适宜性好、年利用小时数长、技术路线简单且推广性较强的优势,应作为我国拓展地热能工业应用场景的优先发展方向。China has abundant hydrothermal low-to medium-temperature geothermal resources,which have great potential for application since their temperature is close to that required for industrial production pro-cesses such as drying and process heating.Based on the investigation of the mature industrial application sce-narios of geothermal energy at home and abroad,the evaluation index system for geothermal energy category in industrial application is established by using analytic hierarchy process(AHP)and selecting resource index,technical index,economic index and safety index.Through the construction of judgment matrix,single-level ranking and consistency check,it is clear that safety,environmental protection and health,minimum required water temperature,minimum water demand,and annual utilization hours are the four important indicators that have a great impact on the evaluation of industrial application of geothermal energy,and their weights are 0.26,0.245,0.135 and 0.083,respectively.This evaluation index system is used to comprehensively evaluate the application scenarios.The results show that four application scenarios,i.e.,milk sterilization(pasteurization),leather tanning,rice drying and vegetable drying,get high scores in the comprehensive evaluation and should be taken as the priority development direction for China to expand the industrial application scenarios of geothermal energy due to the good suitability of geothermal resource,long annual utilization hours,simple technical routes and strong popularization.
