地热水资源开发与环境保护

Exploitation and Environmental Protection of the Geothermal Water Resourcegeothermal water resource

作为巨大的清洁能源,地热水资源已被大量开发及利用。但是清洁能源并不清洁,其由地下深处带到地表的一些化学物质等对地面环境势必造成严重的负面影响即危害。在介绍了地热水资源概况及开发利用现状基础上,对地热水资源开发及利用所带来的环境及环境地质问题进行了简单的介绍,特别是地面沉降、热污染及地热水资源衰减等,并分析了这些环境地质问题产生的机理。对地热水资源开发利用中存在的问题做了简要总结,并为地热水资源的合理开发、科学利用及可持续发展提出加强勘查评价工作,提高利用效率等五余个建议和对策。

As a huge clean and potential energy,the geothermal water resource has been exploited and utilized a lot. However the clean energy is not clean,some chemical substances are transported from the deep underground to the surface which causes serious negative effects to the environment . On the basis of the introduction of the survey of geothermal water resource and its current situation of the exploitation and utilization, the article describes the environmental geological problem and the environ- mental issues in a brief. Especially, the land subsidence,the thermal pollution and the decay of the geo- thermal water resources etc, and analyzes the generated mechanisms of these environmental geological problems. The article also briefly summarizes existing problems in the exploitation of the geothermal water resources, also gives some suggestions and measures to the rational exploitation, the scientific utilization and the sustainable exploitation of the geothermal water resources.
