西藏自治区地热供暖现状和前景分析

Current Situation and Prospect of Geothermal Heating in Tibet

目前,我国地热资源直接利用以采暖为主,地源热泵作为全球地热直接利用主要方式,其效率高、节能环保,既可供热又可制冷,且技术成熟。西藏自治区作为国内地热资源最丰富的地区,蕴藏极其丰富的浅层中低温地热资源且冬季漫长寒冷,农牧民室内采暖以柴薪和牛粪为主。因此,在西藏自治区地热资源品位相对较低的地区,以浅层地热能和水热型地热资源为主,发挥地源热泵技术的优势进行供暖,可减少人们对森林的砍伐、草场的破坏,促进环境的修复,对改善农牧民的生活居住条件,提高西藏自治区人民生活质量,促进当地经济发展,具有重大意义。

At present,the direct utilization of geothermal resources in China is mainly based on heating.As the main way of direct utilization of geothermal resources in the world,ground source heat pump has high efficiency,energy saving and environmental protection.It can provide both heat and cooling,and the technology is mature.As the region with the most abundant geothermal resources in China,Tibet is rich in shallow and low temperature geothermal resources.Winter in Tibet is long and cold.Farmers and herdsmen use firewood and cow dung for indoor heating.Therefore,in the areas with relatively low geothermal resources grade in Tibet,shallow geothermal energy and hydrothermal geothermal resources are mainly used,and the advantages of ground source heat pump technology are taken to provide heating,which can reduce people's deforestation and grassland destruction and promote environmental restoration.It is of great significance to improving the living conditions of farmers and herdsmen,improving the quality of life of the people in Tibet,and promoting the economic development of Tibet.
