摘要

The geothermal resource type of Beijing belongs to low and middle temperature geothermal resources and the geothermal water has been used for over 40 years. After years of exploitation and utilization,problems such as declining water level,low degree of centralized utilization,lagging reinjection,unreasonable utilization methods etc. Occurred in order to set the reasonable direction of Beijing geothermal resources development and utilization,serve the urban functions as the capital,and build a livable city,the distributive characteristics were summarized in this paper by analyzing the distributive features of geotemperature,the hydrogeochemical characteristics and the characteristics of stable isotope. This paper also put forward zonation for geotemperature,geothermal resources utilization program,and potential for further exploitation and utilization. The study gets the protection zonation of geothermal resources based on the distributive characteristics and the potential zonation. The conclusion will hopefully give us the knowledge and understanding of the characteristics and the recharge areas of the geothermal resources. The results and conclusion have a guiding significance for zonation of geothermal protection and exploitation of geothermal resources.
