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.展开更多

Through analysis of the water resources in Beijing from 1980 s up to now, this paper finds the major problems in the exploitation and utilization of groundwater in Beijing lie in the over-exploitation and pollution in groundwater, which are primarily caused by the rapid growth of population, enduring imbalance between exploitation and replenishing of groundwater and the contamination of groundwater. Thus based on this, this paper puts forward proposals and opinions to exploit groundwater in a scientific and moderate way, and to comprehensively protect the groundwater resources and environment in Beijing.展开更多
